Nexperia USA Inc. PBHV9050Z-QF

Overview

PBHV9050Z-QF from Nexperia is a PNP high-voltage low-V_CEsat transistor in SOT223 (SC-73) package, rated for −500 V V_CEO, −250 mA I_C, and −140 mV typical V_CEsat at I_C = −100 mA / I_B = −20 mA. It delivers high h_FE (80–300) at high current and is AEC-Q101 qualified for automotive motor management and flyback converters.

For engineers reviewing the PBHV9050Z-QF datasheet, PBHV9050Z-QF pinout, PBHV9050Z-QF application, or PBHV9050Z-QF equivalent, this device serves as a robust high-voltage switching element where low saturation loss, thermal stability on FR4 PCBs, and automotive-grade reliability are critical in LED driver, SMPS, and telecom hook-switch designs.

Technical Context

This PNP bipolar junction transistor operates with open-base V_CEO = −500 V and supports pulsed I_C up to −500 mA. Its low V_CEsat enables reduced conduction loss in high-voltage switching nodes, while h_FE remains stable across −55 °C to +150 °C ambient range.

Thermal performance is defined by R_th(j-sp) = 20 K/W (with 6 cm² collector pad), enabling sustained operation under moderate power dissipation. Switching times-t_on = 1675 ns, t_off = 1750 ns-are optimized for <1 MHz SMPS topologies requiring fast turn-off with minimal storage delay.

FAQ

What is the maximum safe operating voltage for PBHV9050Z-QF in continuous DC conditions?

The absolute maximum V_CEO is −500 V with open base, verified per IEC 60134 limiting values. For reliable long-term operation, design should maintain ≤ 80 % of this rating (≤ −400 V) under worst-case transients and temperature extremes, especially in automotive environments where load-dump spikes may exceed nominal bus voltage.

Can PBHV9050Z-QF be used in surface-mount reflow processes without thermal damage?

Yes-PBHV9050Z-QF is qualified for standard lead-free reflow per J-STD-020. Its SC-73 package supports peak temperatures up to 260 °C for ≤ 30 seconds. The recommended footprint uses a 6.15 mm × 3.85 mm solder land for the collector pad to ensure mechanical integrity and thermal transfer during reflow and operational life.

How does the dual-collector configuration (pins 2 and 4) affect PCB layout?

Pins 2 and 4 are internally shorted to the same collector node and must be connected to identical copper pour areas on the PCB. This configuration halves effective thermal resistance to solder point (R_th(j-sp) = 20 K/W) and increases current-handling capacity-but requires symmetric thermal vias and equal trace width to avoid current imbalance or localized heating.

Is PBHV9050Z-QF suitable for linear regulation applications?

It can operate in linear mode, but its P_tot = 1400 mW at T_amb = 25 °C (derates to zero at 150 °C) limits usable power dissipation. For example, at −200 mA and −2 V V_CE, dissipation reaches 400 mW-well within safe range with adequate copper area. However, switching-mode use is preferred to minimize heat generation and maximize efficiency.
