Product details

Overview

PBHV9115T-QR from Nexperia is a PNP high-voltage low-V_CEsat transistor in SOT23 package, rated for −150 V V_CEO, −1 A I_C, and −150 mV typical V_CEsat at I_C = −500 mA / I_B = −100 mA. It serves as a robust switching element in automotive LED drivers, HID lighting, and SMPS output stages where high breakdown voltage and low conduction loss are critical.

For engineers reviewing the PBHV9115T-QR datasheet, PBHV9115T-QR pinout, PBHV9115T-QR application, or PBHV9115T-QR equivalent, this device is selected for high-voltage PNP switching with AEC-Q101 qualification, precise saturation behavior under pulsed and DC conditions, and thermal performance validated on FR4 PCBs.

Technical Context

This PNP bipolar junction transistor features a high-voltage epitaxial base structure enabling −150 V collector-emitter blocking capability and −200 V collector-base rating. Its low saturation voltage (−150 mV typ. at I_C/I_B = 5) stems from optimized doping profiles and emitter geometry, supporting efficient switching in 12–48 V automotive systems.

It delivers h_FE = 100–220 at I_C = −50 mA and maintains usable gain (h_FE ≥ 10) even at I_C = −1 A (pulsed), with f_T = 115 MHz confirming suitability for medium-speed switching up to several hundred kHz. Thermal resistance R_th(j-a) = 417 K/W (FR4, single-sided copper) defines its power handling envelope.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−150 V - Enables direct interface with 100 V-class automotive loads and HID lamp ballasts without external snubbing.
I_C	−1 A continuous - Supports sustained current drive for high-brightness LED chains and motor control logic-level switches.
V_CEsat	−150 mV typ. @ I_C = −500 mA, I_B = −100 mA - Reduces conduction loss to ≤75 mW, minimizing self-heating in compact layouts.
h_FE	100–220 @ V_CE = −10 V, I_C = −50 mA - Ensures stable base drive design margin across temperature (−55 °C to +150 °C).
f_T	115 MHz - Validates fast switching capability for PWM frequencies up to 200 kHz with controlled rise/fall times (t_r = 282 ns, t_f = 300 ns).
R_th(j-a)	417 K/W - Defines maximum power dissipation of 300 mW at T_amb = 25 °C on standard FR4; derates linearly above 75 °C.

Pinout & Package

SOT23 (TO-263AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, tin-plated terminations compatible with standard reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control input requiring −100 mA to −200 mA base current for full saturation at I_C = −500 mA to −1 A.
2	Emiter (E)	Common reference terminal tied to higher-potential rail (e.g., battery +12 V); polarity inversion defines PNP operation.
3	Collector (C)	Switched load connection; handles −150 V reverse bias and −1 A continuous current with minimal V_CEsat drop.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive underhood applications per stress test requirements including HTOL, TC, HAST, and ESD.
Low V_CEsat	−150 mV typical at I_C/I_B = 5 ensures <1% voltage overhead in 12 V LED driver strings, improving system efficiency.
High V_CEO	−150 V rating supports direct replacement of legacy transistors in 24/48 V telecom hook-switch and industrial control circuits.
Robust thermal performance	R_th(j-sp) = 70 K/W enables localized heat transfer to PCB copper pour, allowing >200 mW dissipation in thermally enhanced layouts.

Applications

LED Chain Driver

LCD Backlighting

Use Scenario: Driving series-connected white LEDs in automotive instrument clusters with 12–24 V supply.

IC Role / Device Role / Timing Role: High-side PNP switch controlling current through constant-current LED string.

Use Value: Low V_CEsat minimizes voltage headroom loss, enabling longer LED strings within supply constraints while maintaining AEC-Q101 reliability.

Use Scenario: Providing adjustable current to CCFL or edge-lit LED arrays in automotive infotainment displays.

IC Role / Device Role / Timing Role: Linear or PWM-controlled current sink in boost-derived backlight supply path.

Use Value: Stable h_FE over temperature ensures consistent dimming linearity; −150 V rating accommodates transient spikes during cold-crank events.

HID Front Lighting

Automotive Motor Management

Use Scenario: Ignition pulse switching and ballast control in xenon HID headlamp modules.

IC Role / Device Role / Timing Role: Fast-turn-off PNP switch managing high-voltage ignition pulses (up to −100 V) and sustaining current during arc phase.

Use Value: 115 MHz f_T and sub-μs switching times (t_off = 730 ns) support precise pulse-width control for lamp warm-up and regulation.

Use Scenario: Controlling solenoid valves, fuel injectors, or small DC motors in engine control units and body electronics.

IC Role / Device Role / Timing Role: High-side driver interfacing microcontroller GPIO to inductive loads with flyback protection.

Use Value: −200 V V_CBO withstands inductive kickback without clamping diodes; AEC-Q101 qualification ensures lifetime reliability in vibration-prone environments.

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
PHPT612030T	−120 V V_CEO, −3 A I_C, SOT23 package, but higher V_CEsat (−300 mV typ.)	Lower voltage rating limits use in 48 V+ HID or telecom hook-switch; better suited for high-current 12 V motor drives.	Select when peak current >1 A is required and −120 V blocking suffices; verify thermal margin due to higher V_CEsat.
BC807-40,215	−45 V V_CEO, −500 mA I_C, same SOT23 footprint but non-automotive grade	Not AEC-Q101 qualified; unsuitable for automotive ambient temperatures or long-term reliability requirements.	Acceptable only for cost-sensitive industrial prototypes where −45 V rating and non-automotive qualification are acceptable.

Compared with PHPT612030T and BC807-40,215, PBHV9115T-QR uniquely balances −150 V blocking, −1 A current, low −150 mV V_CEsat, and AEC-Q101 compliance-making it the only choice for production automotive lighting and power switching where all four parameters are simultaneously required.

FAQ

Is PBHV9115T-QR pin-compatible with NPN complement PBHV8115T-Q?

No. PBHV9115T-QR is a PNP transistor with Base–Emitter–Collector pinout (1–2–3), while PBHV8115T-Q is an NPN device with identical SOT23 mechanical footprint but reversed polarity and complementary electrical behavior. Circuit redesign is required for substitution; they are functional complements-not pin-for-pin replacements.

What is the maximum allowable base current for continuous operation?

The absolute maximum peak base current is −400 mA (single pulse, t_p ≤ 1 ms), but for continuous DC operation, IB must be limited to ensure junction temperature remains ≤150 °C. At I_C = −1 A, recommended I_B = −200 mA (I_C/I_B = 5) yields safe V_CEsat and thermal margin on FR4 PCBs.

Does PBHV9115T-QR require external base pull-up or pull-down resistors?

Yes. As a bipolar transistor, PBHV9115T-QR requires active base drive: a current-sinking driver (e.g., MCU GPIO with open-drain or dedicated base driver) and a pull-up resistor to V_CC (typically 1–10 kΩ) to ensure fast turn-off and prevent unintended conduction during microcontroller reset or floating states.

Can PBHV9115T-QR be used in linear regulator applications?

It is not optimized for linear regulation. While it can operate in the active region, its V_CEsat-focused design, limited SOA at high V_CE, and thermal resistance (417 K/W) make it unsuitable for sustained linear pass operation. Use is restricted to switching mode (saturation/cutoff) in automotive lighting and power control.
