Product details

Overview

PBHV9050ZF 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) and low thermal resistance (90 K/W to solder point), enabling efficient switching in high-voltage flyback and LED driver stages.

For engineers reviewing the PBHV9050ZF datasheet, PBHV9050ZF pinout, PBHV9050ZF application, or PBHV9050ZF equivalent, key selection criteria include verified −500 V blocking capability, sub-200 mV saturation voltage under pulsed 100 mA load, SOT223 thermal performance with 6 cm² collector pad, and compatibility with wired telecom hook-switch and LCD backlighting topologies.

Technical Context

This device operates as a medium-power PNP bipolar junction transistor optimized for high-voltage switching with minimal conduction loss. Its architecture supports stable DC current gain (h_FE) across −55 °C to +150 °C and maintains low V_CEsat even at elevated junction temperatures due to robust emitter-base doping and optimized base width.

Designed for unidirectional high-side switching, it features symmetrical dual-collector terminals (Pins 2 & 4) to enhance current handling and thermal spreading on FR4 PCBs. The −6 V V_EBO rating and <100 nA I_CBO at 25 °C ensure reliable turn-off integrity in high-impedance bias networks.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−500 V - Enables direct use in 400 V AC rectified bus and telecom −48 V/−75 V systems without series stacking.
I_C	−0.25 A continuous - Supports sustained LED chain current or electronic ballast lamp drive without derating at T_amb ≤ 75 °C.
V_CEsat	−140 mV typ. @ I_C = −100 mA / I_B = −20 mA - Reduces conduction loss to <14 mW, critical for thermally constrained SMPS primary-side switches.
h_FE	80–300 @ V_CE = −10 V, I_C = −50 mA - Allows low-base-drive-current operation, easing bias network design in isolated feedback loops.
R_th(j-sp)	20 K/W - Achieves 1.4 W power dissipation with only 28 °C rise above solder point, supporting compact layout in space-limited LED modules.
f_T	50 MHz - Sufficient for flyback converter switching up to 500 kHz with margin for gate drive propagation delay compensation.
C_c	6 pF - Limits Miller charge injection during fast turn-off, reducing risk of false triggering in high-dV/dt environments like telecom line interfaces.

Pinout & Package

SOT223 (SC-73) plastic surface-mount package with 4 leads, 2.3 mm pitch, and integrated heatsink pad (Pin 2 & Pin 4 both connected to collector). Dimensions: 6.5 mm × 3.5 mm × 1.65 mm body; mounting pad for collector requires 6 cm² copper area for full 1400 mW rating.

Pin/Terminal	Circuit Role	Design Meaning
1	Base	Control input requiring −2 mA to −20 mA drive for full saturation; low V_BEsat (−0.75 V typ.) minimizes base resistor power loss.
2	Collector	Main high-voltage output terminal; electrically tied to Pin 4 for parallel current path and improved thermal conduction to PCB copper.
3	Emitter	Reference node for load connection; must be tied to system ground or negative rail in high-side switch configurations.
4	Collector	Secondary collector terminal sharing internal die connection with Pin 2; used for enhanced thermal routing or redundant trace routing in dense layouts.

Key Features

Feature	Design Value
High-voltage blocking	−500 V V_CEO enables single-device replacement of stacked transistors in 380 V DC bus applications.
Low saturation voltage	−140 mV V_CEsat at 100 mA reduces power loss by >40% versus standard PNP transistors with >300 mV drop.
Dual-collector thermal path	Pins 2 & 4 both connect to collector, allowing doubled copper area attachment and 2× heat spreading efficiency on FR4.
Wide temperature h_FE stability	h_FE remains ≥70 at −55 °C and ≥150 at +100 °C, ensuring consistent gain across industrial ambient ranges.
Low leakage at high voltage	<100 nA I_CES at −360 V ensures reliable off-state isolation in LED string bias networks and telecom ring detection.

Applications

Electronic Ballasts

LED Chain Driver

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
PHPT60303SQ	−60 V V_CEO, −3 A I_C, SOT223; MOSFET-based, no base drive required	Lower voltage rating limits use to <100 V DC systems; higher current capacity suits motor drivers over LED chains	Select when gate-driven simplicity and zero gate charge outweigh need for 500 V blocking.
MJD44H11	−80 V V_CEO, −8 A I_C, TO-220; higher power but lower voltage and larger footprint	Requires external heatsink and voltage clamping for >100 V operation; unsuitable for SMT-only assembly	Choose only for legacy through-hole designs where 500 V capability is not required and thermal mass is available.

Compared with PHPT60303SQ and MJD44H11, PBHV9050ZF uniquely balances 500 V capability, SMT compatibility, and sub-200 mV saturation in a single medium-power package-making it the only viable option for compact, high-voltage LED drivers and telecom hook-switches without redesigning board layout or adding protection components.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current (I_BM) is −200 mA per pulse (t_p ≤ 1 ms), but continuous DC base current must be limited to ≤ −20 mA to avoid thermal runaway. At I_C = −100 mA, recommended I_B = −20 mA ensures full saturation while maintaining T_j < 125 °C on standard FR4 with 6 cm² collector pad.

Can PBHV9050ZF replace a MOSFET in high-voltage switching applications?

No-it is a bipolar transistor requiring sustained base current, unlike voltage-driven MOSFETs. However, it offers lower conduction loss than many high-voltage P-channel MOSFETs below 200 mA, especially where gate drive complexity or cost must be minimized. Use only where base drive circuitry is already present or easily added.

Is PBHV9050ZF qualified for automotive applications?

No-this part is explicitly marked non-automotive qualified per Revision History v.3 (20241009). It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia recommends the PBHV9050Z-Q variant, which shares identical electrical specs but includes full qualification documentation and traceability.

How does the dual-collector configuration affect PCB layout?

Pins 2 and 4 are internally shorted to the collector, so both must be connected to the same high-current net-ideally a large copper pour. This doubles thermal conduction area and allows symmetric trace routing to reduce inductance. Do not leave either pin floating or route them to separate nets, as this creates internal current imbalance and localized heating.
