Nexperia USA Inc. PBHV9115X,115

Overview

PBHV9115X,115 from Nexperia is a PNP high-voltage low-V_CEsat bipolar junction transistor in SOT89 package, rated for −150 V V_CEO, −1 A continuous collector current, and −200 mV typical V_CEsat at I_C = −500 mA / I_B = −50 mA. It serves as a high-efficiency switching element in LED chain drivers and telecom hook-switch circuits where high breakdown voltage and minimal conduction loss are critical.

For engineers reviewing the PBHV9115X,115 datasheet, PBHV9115X,115 pinout, PBHV9115X,115 application, or PBHV9115X,115 equivalent, this device is selected for high-voltage linear/switching roles requiring stable h_FE > 100 at −100 mA, thermal resistance R_th(j-sp) = 20 K/W with collector pad, and operation up to 150 °C junction temperature.

Technical Context

This PNP BJT operates with open-base V_CEO = −150 V and peak V_CESM = −200 V, supporting robust isolation in off-state telecom and SMPS primary-side control. Its h_FE remains ≥10 at −1 A (pulsed), enabling reliable base drive scaling for high-current loads without secondary gain collapse.

V_CEsat is specified at −200 mV (typ) to −300 mV (max) under I_C/I_B = 10, directly reducing power dissipation in saturated switching. The device exhibits f_T = 115 MHz and low C_c = 10 pF, supporting fast turn-on (t_on = 290 ns) and turn-off (t_off = 730 ns) in pulse-driven applications.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −400 mA per datasheet limiting values, but continuous I_B must be limited to ensure junction temperature stays within 150 °C. At I_C = −1 A and h_FE = 10 (min), required I_B is −100 mA; sustained operation above −50 mA demands thermal derating based on R_th(j-a) = 240 K/W on standard FR4.

Can PBHV9115X,115 replace a MOSFET in high-voltage switching applications?

No-it is a bipolar transistor requiring continuous base current drive, unlike voltage-controlled MOSFETs. While it achieves low V_CEsat, its gate charge and drive complexity differ fundamentally; substitution is viable only where base drive circuitry already exists and switching speed requirements align with its 730 ns t_off.

Is the SOT89 package lead-free and RoHS compliant?

Yes-PBHV9115X,115 is manufactured using lead-free solderable terminations and complies with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, with homogeneous material declarations available upon request through Nexperia's compliance portal.

Does this part support pulsed operation beyond its DC ratings?

Yes-peak collector current I_CM is rated at −2 A for single pulses ≤1 ms, and transient thermal impedance data (Fig. 2–3) confirm safe operation at 1 A for duty cycles ≤2% with pulse widths ≤100 µs, provided PCB layout maintains thermal integrity of the collector pad.
