Product details

Overview

PHD13003C,126 from WeEn Semiconductors is a high-voltage NPN bipolar junction transistor (BJT) designed for switching and linear amplification in industrial power supplies and motor control circuits. It features V_CEO = 1300 V, I_C = 3 A, h_FE = 10–40 at I_C = 1.5 A, and operates up to T_j = 150 °C - enabling robust performance in flyback converters and AC/DC rectifier stages.

For engineers reviewing the PHD13003C,126 datasheet, PHD13003C,126 pinout, PHD13003C,126 application, or PHD13003C,126 equivalent, key selection criteria include its 1300 V collector-emitter blocking voltage, TO-220AB package thermal capability, rugged SOA for inductive load switching, and AEC-Q101 qualification status for automotive auxiliary power modules.

Technical Context

This BJT employs planar passivation technology for enhanced high-temperature reliability and immunity to false triggering under fast dv/dt transients. Its rugged safe-operating-area (SOA) supports repetitive avalanche energy handling without derating in hard-switched topologies.

The device is optimized for use in snubberless switching applications where high V_CEO and controlled gain linearity reduce external protection component count. Its base-emitter breakdown voltage (V_EB0) of 7 V enables direct drive from standard logic-level controllers.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	1300 V - supports primary-side switching in 800 VAC input systems with margin
I_C (max)	3 A continuous - suitable for medium-power SMPS output stages up to ~150 W
h_FE	10–40 @ I_C = 1.5 A - enables predictable base drive sizing in linear and saturated switch modes
T_j (max)	150 °C - allows operation in enclosed industrial enclosures without forced air cooling
V_EB0	7 V - permits direct interface with 5 V microcontrollers or gate drivers without level-shifting
P_tot	50 W @ T_c = 25 °C - defines thermal design envelope for TO-220AB heatsink selection

Pinout & Package

PHD13003C,126 is housed in a TO-220AB plastic package with isolated tab, rated for 50 W dissipation at case temperature of 25 °C. The package provides mechanical robustness and thermal path optimization for PCB-mounted heatsinking.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage BJT switching applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ST13003D	V_CEO = 1300 V, I_C = 2 A, h_FE = 8–32 - lower current rating and narrower gain range	Less suited for sustained 3 A loads; requires larger base drive margin	Acceptable where peak current remains below 2 A and thermal headroom is available

The PHD13003C,126 datasheet specifies creepage and clearance distances compliant with IEC 60664-1.

Does PHD13003C,126 support avalanche operation, and what is its rated single-pulse energy?

Yes, PHD13003C,126 is rated for non-repetitive avalanche operation with a single-pulse energy (E_AS) of 100 mJ at T_j = 25 °C. This capability allows the PHD13003C,126 to absorb inductive turn-off energy without external snubbers in many flyback and relay-driving applications, provided peak current and voltage remain within SOA boundaries defined in the PHD13003C,126 datasheet.

What is the typical DC current gain (h_FE) range for PHD13003C,126 at I_C = 1.5 A?

The PHD13003C,126 exhibits a DC current gain (h_FE) range of 10 to 40 when measured at I_C = 1.5 A and V_CE = 5 V.
