Product details

2.4 V rail clamp or reference — AEC-Q101 qualified

The PDZVTFTR2.4B is a 2.4 V Zener diode from ROHM's automotive-grade series, rated for 1 W continuous power dissipation in a SOD-128 surface-mount package. The ±6.25% tolerance on the nominal Zener voltage means the actual clamp point sits between 2.25 V and 2.55 V — tight enough for a low-voltage supply rail clamp or a simple shunt reference in an automotive ECU or sensor module.

1 W in SOD-128 — thermal reality for continuous use

At 1 W max power, the junction temperature is rated to 150 °C. In a continuous shunt regulator, the power dissipated is Vz × Iz; at 2.4 V that means about 400 mA Zener current before hitting the 1 W ceiling. The SOD-128 package has a small footprint — the copper pad area under the cathode tab sets the effective thermal resistance, so a solid ground-plane connection is needed to keep junction temperature below the 150 °C limit in a hot under-hood environment.

Active production — no obsolescence concern

For volume production or a BOM line that needs an automotive-grade 2.4 V Zener, this part is a current-catalog choice — no supply-risk flag from the manufacturer.

Frequently asked questions

Is PDZVTFTR2.4B equivalent to other 2.4 V Zener diodes?

The PDZVTFTR2.4B is a 2.4 V Zener with 1 W power rating, ±6.25% tolerance, and AEC-Q101 automotive qualification in a SOD-128 package. A standard commercial-grade 2.4 V Zener in a different package (e.g., SOD-123 or MELF) may have a different thermal footprint and lack the automotive stress-tested qualification. For a direct functional cross, the ROHM PTZTFTE253.0B is a 3.0 V Zener in the same series and package — not a voltage-equivalent substitute.
