Nexperia USA Inc. PBHV9050Z,115

Overview

PBHV9050Z from Nexperia is a PNP high-voltage bipolar junction transistor (BJT) designed for switching in high-voltage DC-DC and flyback topologies. It delivers 500 V collector-emitter peak voltage (VCESM), 250 mA continuous collector current (IC), and ultra-low VCEsat of −140 mV at IC = −100 mA / IB = −20 mA, enabling efficient operation in LED driver and telecom hook-switch circuits.

For engineers reviewing the PBHV9050Z datasheet, PBHV9050Z pinout, PBHV9050Z application, or PBHV9050Z equivalent, key selection criteria include its SOT223 package thermal performance (Rth(j-sp) = 20 K/W), high hFE (80–300 at −50 mA), low leakage (ICES ≤ −100 nA), and verified suitability for electronic ballasts and LCD backlighting designs requiring stable high-voltage switching.

Technical Context

This PNP BJT operates with open-base VCEO = −500 V and peak VCESM = −500 V under zero base-emitter bias, supporting robust isolation in off-state high-voltage rails. Its DC current gain (hFE) remains ≥80 up to −100 mA at 25 °C, and VCEsat stays below −200 mV across −10 mA to −100 mA with forced β = 5–20.

Switching performance is characterized by ton = 1675 ns and toff = 1750 ns under standardized conditions (VCC = −20 V, IC = −50 mA, IBon = −5 mA, IBoff = 10 mA), while fT = 50 MHz confirms usable bandwidth for medium-speed power control. Thermal resistance to solder point (Rth(j-sp) = 20 K/W) enables direct PCB heatsinking via the collector pad.

FAQ

What is the maximum continuous power dissipation for PBHV9050Z on a standard FR4 PCB?

The PBHV9050Z delivers 700 mW total power dissipation when mounted on a standard FR4 PCB with single-sided copper and tin plating. With a 6 cm² collector pad, this increases to 1400 mW at Tamb ≤ 25 °C-enabling higher current operation in thermally optimized layouts without external heatsinks.

Can PBHV9050Z replace a MOSFET in high-voltage switching applications?

Yes, but with design trade-offs: it offers lower gate-drive complexity than MOSFETs (no gate charge, no driver IC needed), yet requires sustained base current. Its −140 mV VCEsat at −100 mA yields lower conduction loss than many 500 V MOSFETs in the same package, though switching speed is slower than modern Si MOSFETs.

Is PBHV9050Z qualified for automotive applications?

No. Per Nexperia's revision history (v.3, October 2024), PBHV9050Z is explicitly designated non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends its −Q qualified variants such as PBHV9050Z-Q.

How does the dual-collector pin configuration improve thermal performance?

Pins 2 and 4 are internally shorted to the same collector node and externally connected to the large metal tab. This doubles the solder joint interface area and reduces thermal resistance from junction to solder point (Rth(j-sp) = 20 K/W), allowing more efficient heat transfer into the PCB copper compared to single-terminal SOT223 devices.
