Product details

Overview

PBHV9115X-QX from Nexperia is a PNP high-voltage low-V_CEsat bipolar junction transistor 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 operates in automotive-grade SOT89 package and serves as a high-efficiency switching element in LED chain drivers and automotive motor control circuits.

For engineers reviewing the PBHV9115X-QX datasheet, PBHV9115X-QX pinout, PBHV9115X-QX application, or PBHV9115X-QX equivalent, key selection criteria include its AEC-Q101 qualification, −150 V blocking capability, low saturation voltage under high-current drive, and thermal performance on FR4 PCB with 6 cm² collector pad.

Technical Context

This PNP transistor uses epitaxial base technology to achieve high h_FE (100–220 at I_C = −50 mA) while maintaining robust high-voltage operation up to −200 V peak. Its low V_CEsat enables reduced conduction loss in high-side switch configurations where emitter is tied to supply rail.

Switching performance is characterized by 290 ns turn-on time and 730 ns turn-off time under specified test conditions (V_CC = −6 V, I_C = −0.5 A), with transient thermal impedance optimized for pulsed loads in automotive lighting and power management.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−150 V - Maximum DC collector-emitter voltage with base open; defines safe operating range in high-side switch topologies
I_C	−1 A - Continuous collector current rating; supports sustained load driving in LED backlight and motor control
V_CEsat	−200 to −300 mV - Low saturation voltage at I_C = −500 mA / I_B = −50 mA; minimizes power dissipation in linear/switching modes
h_FE	100–220 - DC current gain at V_CE = −10 V, I_C = −50 mA; ensures reliable base drive margin across temperature
R_th(j-sp)	20 K/W - Junction-to-solder-point thermal resistance with 6 cm² collector pad; enables 1.5 W power dissipation at T_amb ≤ 25 °C
f_T	115 MHz - Transition frequency at V_CE = −10 V, I_C = −10 mA; supports fast switching in SMPS and telecom hook-switch applications
AEC-Q101	Qualified - Certified for automotive use per stress test standard; validated for temperature cycling, HTRB, and ESD robustness

Pinout & Package

Package: SOT89 (SC-62), surface-mounted plastic package, 4.5 mm × 2.5 mm × 1.5 mm body, 1.5 mm lead pitch, collector tab thermally enhanced for PCB mounting.

Pin/Terminal	Circuit Role	Design Meaning
1 - E	Emitter	High-side reference node; connected to positive rail in common-emitter switch configuration
2 - C	Collector	Main current output terminal; electrically and thermally coupled to PCB copper pad for heat dissipation
3 - B	Base	Current-controlled input; requires −50 mA drive for full saturation at −500 mA load

Key Features

Feature	Design Value
High-voltage blocking	−200 V V_CESM peak rating enables use in 100 V+ automotive battery systems with surge margin
Low V_CEsat	−200 mV typ. at I_C/I_B = 10 reduces conduction loss by >40% vs. standard PNP transistors at same current
High h_FE at high I_C	30 min. at I_C = −1 A ensures stable gain under full-load switching without excessive base drive
Thermal optimization	R_th(j-sp) = 20 K/W with 6 cm² pad allows 1.5 W dissipation - critical for space-constrained LED driver modules
AEC-Q101 qualification	Validated for automotive ambient range (−55 °C to +150 °C) and lifetime reliability in engine bay and cabin electronics

Applications

LED Chain Driver

LCD Backlighting

Use Scenario: Driving series-connected white LEDs from 24 V or 48 V automotive supply rails with PWM dimming.

IC Role / Device Role / Timing Role: High-side PNP switch controlling current path to LED string; operates in saturated switching mode.

Use Value: −200 mV V_CEsat limits power loss to <100 mW at 500 mA, enabling compact thermal design without heatsink.

Use Scenario: Providing regulated current to CCFL or edge-lit LED arrays in automotive instrument clusters and infotainment displays.

IC Role / Device Role / Timing Role: Constant-current sink switch in boost-derived current source topology; handles repetitive 100–500 Hz dimming pulses.

Use Value: 730 ns t_off and 290 ns t_on support clean PWM edges without ghosting or brightness droop.

Automotive Motor Management

Hook Switch for Wired Telecom

Use Scenario: Controlling small DC motors (e.g., HVAC flaps, seat adjusters) in 12 V/24 V vehicle networks with reverse-polarity protection.

IC Role / Device Role / Timing Role: High-side driver in half-bridge or standalone configuration; interfaces with microcontroller GPIO via base resistor network.

Use Value: −150 V V_CEO withstands load-dump transients up to ISO 7637-2 Pulse 5a (−150 V), eliminating need for external clamping.

Use Scenario: Implementing line interface hook-switch function in VoIP gateways and analog telephone adapters compliant with GR-909 and ITU-T Q.551.

IC Role / Device Role / Timing Role: Polarity-insensitive loop closure device; switches between on-hook (open) and off-hook (closed) states.

Use Value: −200 V V_CB rating supports 120 V RMS ring signal handling with safety margin; low leakage (<100 nA I_CES) prevents false off-hook detection.

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
PHPT60105XQ	Same SOT89 package, −100 V V_CEO, −1.5 A I_C, −180 mV V_CEsat; lower voltage rating but higher current and lower saturation voltage	Not suitable for 150 V automotive load-dump environments; better for 48 V telecom or industrial SMPS where current density is priority	Select when system max V_CE stays below −100 V and lower conduction loss at >1 A is required
BCP53-16Q	SOT89 package, −45 V V_CEO, −1 A I_C, −500 mV V_CEsat; significantly higher saturation voltage and lower voltage rating	Only appropriate for 12 V automotive accessories or consumer electronics; lacks AEC-Q101 qualification	Choose only for cost-sensitive non-automotive designs where −45 V rating suffices and thermal budget permits higher V_CEsat

Compared with PHPT60105XQ and BCP53-16Q, PBHV9115X-QX uniquely balances −150 V ruggedness, −200 mV V_CEsat, and AEC-Q101 compliance-making it the sole option for automotive LED drivers requiring both high-voltage transient immunity and low-loss switching.

FAQ

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −400 mA per datasheet Table 5, but continuous operation must be limited to ensure junction temperature remains ≤150 °C. At I_C = −1 A and typical h_FE = 30, I_B ≈ −33 mA is sufficient for saturation; sustained base currents above −100 mA require thermal derating based on R_th(j-a) = 240 K/W on standard FR4.

Can PBHV9115X-QX replace BC807-40 in an existing design?

No - BC807-40 is a −45 V, −500 mA general-purpose PNP in SOT23. PBHV9115X-QX has triple the voltage rating and double the current, but its SOT89 footprint, thermal pad requirements, and higher base drive needs make it mechanically and electrically incompatible without PCB and drive circuit redesign.

Is the collector tab electrically isolated from the die?

No - the collector is internally connected to the metal tab of the SOT89 package. The tab must be soldered to a dedicated PCB copper area serving as both electrical connection and thermal path; isolation requires insulating thermal interface material and careful layout to avoid shorting to adjacent traces.

Does the AEC-Q101 qualification cover PPAP submission support?

Yes - Nexperia provides full PPAP documentation (including PSW, ISIR, test reports, and process flow diagrams) for PBHV9115X-QX upon request. Aetrix Electronics can coordinate direct access to Nexperia's certified PPAP package for Tier 1 automotive customers requiring AIAG-compliant release materials.
