Product details

Overview

PBHV9115Z-QX from Nexperia is a PNP high-voltage low-V_CEsat bipolar transistor in SOT223 (SC-73) package, rated for −150 V V_CEO, −1 A continuous I_C, and −150 mV typical V_CEsat at I_C = −500 mA / I_B = −100 mA. It delivers high h_FE (100–220 at −50 mA) and AEC-Q101 qualification, enabling robust switching in automotive LED drivers and HID front lighting.

For engineers reviewing the PBHV9115Z-QX datasheet, PBHV9115Z-QX pinout, PBHV9115Z-QX application, or PBHV9115Z-QX equivalent, key selection criteria include verified −150 V blocking capability, low saturation voltage under high-current drive, thermal resistance to solder point (20 K/W), and AEC-Q101 compliance for automotive-grade reliability.

Technical Context

This PNP BISS transistor uses a breakthrough in small-signal (BISS) structure to achieve both high voltage tolerance and low saturation loss-uncommon in medium-power discrete transistors. Its design targets high-efficiency linear and switching operation where base drive efficiency and thermal management are critical.

It operates with open-base V_CEO = −150 V and supports peak I_CM = −2 A pulses, while maintaining h_FE ≥ 10 at −1 A (pulsed), enabling stable current gain across wide load ranges. The dual-collector pin configuration (Pins 2 & 4) enhances heatsinking in FR4 PCB layouts.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−150 V: Maximum safe collector-emitter reverse bias before breakdown in open-base condition.
I_C (continuous)	−1 A: Continuous DC collector current rating at T_amb ≤ 25 °C with proper PCB heatsinking.
V_CEsat	−150 to −300 mV @ I_C = −500 mA / I_B = −100 mA: Low conduction loss enables high-efficiency switching in LED/HID drivers.
h_FE	100–220 @ V_CE = −10 V, I_C = −50 mA: High DC current gain reduces required base drive current.
R_th(j-sp)	20 K/W: Thermal resistance from junction to solder point on 6 cm² collector pad-critical for thermal design in automotive modules.
AEC-Q101	Qualified: Meets stress test requirements for discrete semiconductors in automotive applications.

Pinout & Package

SOT223 (SC-73) medium-power surface-mount plastic package with 4 leads, 2.3 mm pitch, and integrated heatsink pad (Pin 2 & Pin 4 both connected to collector). Dimensions: 6.5 × 3.5 × 1.65 mm body; mounting pad for collector recommended at 6 cm² for full 1.4 W power dissipation.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control terminal; accepts negative base current to turn on PNP conduction path.
2	Collector (C)	Main high-voltage current sink; electrically tied to Pin 4 for enhanced thermal and current handling.
3	Emitter (E)	High-side reference node; connects to supply rail in high-side switch configurations.
4	Collector (C)	Duplicate collector terminal-used for thermal relief and parallel current routing to PCB copper.

Key Features

Feature	Design Value
High-voltage blocking	−150 V V_CEO enables direct interface with 12–48 V automotive bus systems without external clamping.
Low V_CEsat	−150 mV typical at 500 mA reduces power loss by >50% vs. standard PNP transistors in LED current regulation.
Dual-collector thermal path	Pins 2 & 4 both connect to collector, allowing dual thermal vias and 6 cm² copper pad for 1.4 W dissipation at T_amb = 25 °C.
AEC-Q101 qualification	Validated for automotive temperature range (−55 to +150 °C) and mechanical stress, supporting under-hood deployment.

Applications

Use Scenario: Constant-current switching for multi-LED strings in automotive cabin lighting or instrument clusters.

IC Role / Device Role / Timing Role: High-side PNP switch controlling cathode-side current flow with fast turn-on/turn-off (<730 ns off-time).

Use Value: −150 mV V_CEsat minimizes heat generation per string, enabling compact thermal design without active cooling.

Use Scenario: PWM-controlled backlight dimming in automotive infotainment displays.

IC Role / Device Role / Timing Role: Linear or switching current source regulating white LED current up to 1 A peak.

Use Value: Stable h_FE (≥100 at −50 mA) ensures consistent brightness control across temperature and unit variance.

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
PBHV9115Z	Same die, non-AEC-Q101 qualified; identical electrical specs and package.	Not certified for automotive use; suitable for industrial/commercial LED drivers only.	Select when AEC-Q101 compliance is not required and cost sensitivity is higher.
PN2907A	Lower V_CEO (−60 V), lower I_C (−600 mA), no dual-collector thermal path.	Unsuitable for 48 V automotive bus or HID ignition; limited to low-voltage linear regulators.	Choose only for legacy designs below 40 V and <500 mA loads where thermal margin is ample.

Compared with PBHV9115Z-QX, PBHV9115Z lacks automotive qualification but matches all electrical performance, while PN2907A falls short in voltage, current, and thermal capability-making it unsuitable for modern automotive LED/HID systems requiring −150 V and −1 A operation.

FAQ

What is the maximum allowable junction temperature for PBHV9115Z-QX?

The absolute maximum junction temperature (T_j) is 150 °C, as defined in the limiting values table. Operation above this threshold risks permanent device degradation. Derating is required above 25 °C ambient-e.g., at 100 °C ambient, maximum continuous power drops to ~0.4 W when mounted on standard FR4 with 6 cm² collector pad.

Can PBHV9115Z-QX be used in high-frequency switching applications?

Yes-it achieves f_T = 115 MHz at V_CE = −10 V, I_C = −10 mA, making it suitable for PWM dimming up to several hundred kHz. However, its 730 ns turn-off time limits use in >500 kHz SMPS; best suited for LED drivers and motor control where switching frequency is ≤200 kHz.

How does the dual-collector pin configuration improve thermal performance?

Pins 2 and 4 are internally connected to the collector and designed for separate soldering to large copper areas. This doubles thermal conduction paths to the PCB, reducing R_th(j-sp) to 20 K/W (vs. ~89 K/W with single-pin mounting), enabling 1.4 W dissipation at 25 °C ambient-critical for automotive under-hood reliability.

Is PBHV9115Z-QX pin-compatible with NPN complements like PBHV8115Z-Q?

No-PBHV9115Z-QX (PNP) and PBHV8115Z-Q (NPN) share the same SOT223 package outline and pin numbering, but polarity reversal means base and emitter roles are inverted. Direct substitution requires circuit topology changes; they are functional complements, not drop-in replacements.
