Product details

Overview

PBHV9050T-QR from Nexperia is a PNP high-voltage low-V_CEsat transistor in SOT23 package, rated for −500 V V_CEO, −150 mA I_C, and −95 mV typical V_CEsat at I_C = −50 mA / I_B = −10 mA. It serves as a high-efficiency switching element in flyback converters and automotive motor management circuits where high breakdown voltage and low conduction loss are critical.

For engineers reviewing the PBHV9050T-QR datasheet, PBHV9050T-QR pinout, PBHV9050T-QR application, or PBHV9050T-QR equivalent, this device is selected for high-voltage PNP switching roles requiring AEC-Q101 qualification, stable h_FE > 100 at −10 mA, and thermal resistance R_th(j-sp) = 70 K/W on FR4 PCB.

Technical Context

This transistor operates as a saturated-switching PNP device with verified −500 V collector-emitter blocking capability under open-base conditions and −6 V emitter-base rating. Its design supports pulsed I_C up to −500 mA and maintains h_FE ≥ 80 at −50 mA (pulsed), enabling robust drive in telecom hook-switch and LED chain driver topologies.

V_CEsat remains ≤ −200 mV across −20 mA to −100 mA at T_amb = 25 °C with I_C/I_B = 5, and its f_T = 50 MHz ensures adequate bandwidth for SMPS control loop integration. C_c = 6 pF and C_e = 170 pF define its small-signal capacitance profile for switching transient optimization.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−500 V - Enables direct use in 400 V AC rectified bus and flyback primary-side switching without cascading.
I_C	−150 mA continuous - Supports LED chain drivers with up to 12 series LEDs at 15 mA per string.
V_CEsat	−95 mV typ. @ −50 mA/−10 mA - Reduces conduction loss to < 4.75 mW, critical for thermally constrained SOT23 layouts.
h_FE	100–300 @ −10 mA - Ensures reliable base drive margin with standard logic-level current sources.
R_th(j-sp)	70 K/W - Allows 215 mW dissipation before junction exceeds 125 °C when solder-point cooled on FR4.
f_T	50 MHz - Supports gate-drive signal integrity in 1–2 MHz SMPS auxiliary bias supplies.
C_e	170 pF - Dominates input capacitance; sets Miller-effect-limited turn-on speed in high-dV/dt environments.

Pinout & Package

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
PHPT60303SQ	−60 V V_CEO, −3 A I_C, SOT223 package - lower voltage, higher current, larger footprint.	Not suitable for >100 V bus applications; used in 24 V industrial motor drivers.	Select only if system voltage < 48 V and thermal budget allows SOT223 mounting.
BCX56-16	−80 V V_CEO, −1 A I_C, −500 mV V_CEsat - lower voltage, higher saturation loss, same SOT23.	Used in non-automotive 24 V relay drivers; lacks AEC-Q101 qualification.	Acceptable for cost-sensitive consumer lighting where −500 V rating is unnecessary.

Compared with PHPT60303SQ and BCX56-16, PBHV9050T-QR uniquely delivers −500 V blocking in SOT23 while maintaining sub-100 mV V_CEsat, making it irreplaceable in space-constrained, high-voltage automotive and industrial flyback designs.

FAQ

What is the maximum safe operating voltage for PBHV9050T-QR in continuous DC mode?

The absolute maximum V_CEO is −500 V with open base, verified per IEC 60134 limiting values. Operation above −450 V DC is permitted only with derated power dissipation and confirmed board layout clearance per IPC-2221B Class B requirements for 500 V working voltage.

Does PBHV9050T-QR require a base resistor in all switching applications?

Yes - a base resistor is mandatory to limit I_B and ensure saturation. For −50 mA I_C, a 4.7 kΩ resistor from −5 V logic source provides −1.06 mA I_B, achieving I_C/I_B ≈ 47, well within the 5–20 range where V_CEsat remains ≤ −200 mV.

Can PBHV9050T-QR be used in linear regulator configurations?

No - its design targets saturated switching, not linear operation. The −500 V V_CEO and low V_CEsat reflect optimization for on/off states; sustained linear-mode operation risks thermal runaway due to limited SOA at high V_CE and moderate I_C.

Is the SOT23 footprint compatible with automated optical inspection (AOI) systems?

Yes - the standardized SOT23 outline (Figure 12) and marking code "LL%" (Table 4) meet IPC-A-610 Class 2 solder joint acceptance criteria. Reflow footprint dimensions in Figure 13 support 100% AOI coverage of pad wetting and lateral offset.
