Package: TO-220 (13009 also TO-3P) · Pin-compatible replacements with immediate Shenzhen spot stock
The MJE13005/13007/13009 ladder is the high-voltage NPN switch line of ATX supplies, chargers, adapters and ballast circuits: 400V sustaining, 700V blocking, and 4A / 8A / 12A of collector current in the same TO-220 body - the 13007 being the half-bridge classic that every ATX repair bench has burned and replaced. Part of the repair culture treats them as MOSFETs because of where they sit; the drive reality is bipolar, through a base network that dies with them. The rating sheet hides one more misread: 400V and 700V are simultaneous numbers (VCEO and VCBO), not two competing parts.
Verified Pin-Compatible Replacements (3 verified alternatives)
The 12A Top Rung
Shenzhen Spot Stock (24-48h Dispatch)
The current ceiling of the ladder: 12A and 100W against the 8A/80W of the 13007, same B-C-E lead order, same 400V sustaining figure - the safe direction of the ladder, with the TO-3P body available where dissipation mattered.
Same 400V VCEO / 700V VCBO pair of ratings as every member.
The 4A Adapter-Class Rung
Shenzhen Spot Stock (24-48h Dispatch)
The bottom rung of the power ladder: 4A and 75W - the adapter, charger and ballast part, same pin order, same voltage pair, a third of the current.
Identical 400V/700V ratings - the ladder moves current and dissipation only.
The 450V Grade for 220-240V Mains
Shenzhen Spot Stock (24-48h Dispatch)
The suffix grades raise the dielectric: VCEO 450V and VCBO toward 800-850V where the base part carries 400V/700V - the honest choice for 220-240VAC input stages and ballast transients.
The whole point of the suffix: more sustaining and blocking headroom at the same current class.
Buyer & Quality Checklist for Sourcing Alternatives
- The two voltage numbers are simultaneous ratings, not alternatives: VCEO 400V (sustaining, used by the circuit) and VCBO 700V (blocking, a junction limit) on every member of the ladder. The "700V transistor" phrasing in repair lists is a datasheet misread.
- B-C-E lead order with the tab on the collector: unlike the small-signal E-B-C culture, a flipped insertion here puts the base drive on the heatsink - and the circuit fails in ways that look like a dead part.
- These are bipolars in MOSFET positions: ATX half-bridge and two-transistor forward stages deliver real base current through a drive transformer and network. Substituting a MOSFET, or trusting a "MOSFET equivalent" claim, fails on drive topology before it fails on parameters.
- The base network dies with the transistor. Replace the surrounding base resistors, diodes and drive-rail parts in the same repair, or the fresh 13007 inherits the fault that killed the first one.
- Ladder direction: up freely (12A/100W into an 8A socket), down only with the load re-measured (4A/75W is a third of the current). In half-bridge duty fit both sides in one generation - mixed dies unbalance current sharing.
- For 220-240VAC and ballast duty, order the A / AH suffix grades (450V VCEO, VCBO toward 800-850V) rather than the base part - repeated mains-transient failures in the same socket are a voltage-grade complaint, not a brand one.
Frequently Asked Technical Questions
Q: Can MJE13009 replace MJE13007?
A: Yes - it is the safe direction of the ladder: 12A/100W against 8A/80W, same B-C-E pin order and the same 400V/700V ratings, with TO-220 and TO-3P bodies available. The reverse substitution is legal only after the working current is re-measured.
Q: Is the MJE13007 a 400V or a 700V transistor?
A: Both at once: VCEO 400V (collector-emitter, the sustaining rating the circuit lives on) and VCBO 700V (collector-base, a junction blocking limit). They are two specifications of one part, not two parts.
Q: Can I use a MOSFET instead of an MJE13007?
A: Not without redesigning the drive: the 13007 is an NPN bipolar driven by base current through a network, and a MOSFET needs voltage drive with its own gate circuit. The TO-220 position looks the same; the drive requirement is a different kind of thing.
