Nexperia USA Inc. PBHV9560Z-QX

Overview

PBHV9560Z-QX from Nexperia is a PNP high-voltage bipolar junction transistor in SOT223 (SC-73) package, rated for −600 V V_CEO, −0.5 A I_C, and −140 mV typical V_CEsat at I_C = −100 mA / I_B = −20 mA. It delivers high h_FE (70–130 at −50 mA) and is AEC-Q101 qualified for automotive switching applications including HID front lighting and motor management.

For engineers reviewing the PBHV9560Z-QX datasheet, PBHV9560Z-QX pinout, PBHV9560Z-QX application, or PBHV9560Z-QX equivalent, this device is selected for high-voltage PNP switching where low saturation voltage, thermal robustness on FR4 PCBs, and automotive-grade reliability are critical design requirements.

Technical Context

This PNP transistor operates as a high-side switch in off-line power stages, supporting peak collector-emitter voltages up to −600 V with guaranteed safe operation under repetitive avalanche conditions per IEC 60134 limiting values. Its low V_CEsat minimizes conduction loss in linear and quasi-saturated switching modes.

The device features dual-collector terminals (Pins 2 and 4) for enhanced thermal dissipation and current handling, and its h_FE remains stable across −55 °C to +150 °C ambient, enabling use in engine bay and industrial environments without gain collapse.

FAQ

What is the maximum allowable base current for continuous operation?

The datasheet specifies I_C = −0.5 A as the absolute maximum collector current, and base current must be sized to maintain safe operating area (SOA). At I_C = −0.5 A and h_FE ≥ 50 (min at high current), I_B ≥ −10 mA is required. However, continuous I_B should not exceed −20 mA to avoid bond wire overheating, per thermal derating curves in Figure 1.

Can PBHV9560Z-QX replace NPN transistors in existing designs?

No - PBHV9560Z-QX is a PNP device with inverted polarity: it conducts when base is driven negative relative to emitter. Replacing an NPN requires full circuit rework including reversed supply connections, inverted drive logic, and updated gate/base resistor networks. It is not a drop-in substitute.

Is the dual-collector configuration (Pins 2 and 4) mandatory to use?

No - Pins 2 and 4 are internally shorted to the same collector node, so either may be used alone. However, using both significantly improves thermal performance: R_th(j-sp) drops from 89 K/W (standard footprint) to 20 K/W (6 cm² pad), enabling 1.4 W dissipation versus 0.65 W - critical for high-duty-cycle applications.

Does the AEC-Q101 qualification cover all temperature ranges listed in the datasheet?

Yes - AEC-Q101 qualification includes temperature cycling (−40 °C to +125 °C), high-temperature operating life (1000 h at 150 °C), and unbiased high-humidity testing. The full −55 °C to +150 °C operational range is validated per Nexperia's internal automotive release process, extending beyond minimum AEC-Q101 requirements.
