Product details

Dual Schottky rectifier for high-frequency power conversion

The 800 mV forward voltage at 15 A and fast recovery characteristic (≤500 ns, >200 mA) suit it for switch-mode power supply output stages, freewheeling diodes, and polarity protection in industrial and telecom power converters.

175°C junction — thermal headroom for tight enclosures

The 5 µA reverse leakage at 100 V is specified at 25°C; expect leakage to rise with junction temperature, which factors into the thermal budget at full load.

TO-220AB narrow leads — heatsink mounting note

Housed in a TO-220-3 through-hole package with narrow leads (TO-220AB variant), the STPS30H100CTN mounts to a heatsink via the metal tab. The common-cathode configuration means the tab is at cathode potential — insulator pads or thermal interface material may be needed if the heatsink is grounded. The narrow lead form fits standard TO-220 footprints but check the lead pitch against the PCB hole pattern before committing the BOM.

Frequently asked questions

What is the replacement for STPS30H100CTN?

No official replacement order code is recorded in the available lifecycle data. A pin-compatible alternative within the STPS30H100 family may exist — verify the specific suffix and electrical ratings against the original BOM requirement before substituting. For dual-sourcing options, contact a distributor with the full application parameters.

What are the specifications of STPS30H100CTN?

The STPS30H100CTN is a dual Schottky rectifier with common-cathode configuration. Key ratings: 100 V reverse voltage, 15 A average rectified current per diode, 800 mV forward voltage at 15 A, 5 µA reverse leakage at 100 V, fast recovery ≤500 ns, and -40°C to 175°C junction temperature range. Package is TO-220-3 (TO-220AB narrow leads).

Can STPS30H100CTN be used as a replacement for STPS30H100CT?

The STPS30H100CTN and STPS30H100CT share the same base product number STPS30H100, indicating they belong to the same family. The suffix 'N' typically denotes a lead-free or specific packaging variant. Verify the electrical ratings and package dimensions of the original STPS30H100CT against the STPS30H100CTN datasheet to confirm form-fit-function compatibility before substitution.
