Product details

Overview

PBHV9115TLHR from Nexperia is a PNP high-voltage low-V_CEsat transistor in SOT23 package, rated for −150 V V_CEO, −1 A continuous collector current, and −300 mV V_CEsat at I_C = −500 mA / I_B = −100 mA. It serves as a high-efficiency switching element in LED chain drivers and SMPS high-side control stages.

For engineers reviewing the PBHV9115TLHR datasheet, PBHV9115TLHR pinout, PBHV9115TLHR application, or PBHV9115TLHR equivalent, this device is selected for high-voltage PNP switching where low saturation voltage, thermal robustness on FR4 PCBs, and compact SOT23 footprint are critical design constraints.

Technical Context

This transistor operates as a single-polarity, medium-power PNP switch with verified operation up to T_j = 150 °C and ambient range of −55 °C to +150 °C. Its DC current gain (h_FE) spans 70–300 at −50 mA, dropping to ≥10 at −1 A pulsed, supporting stable biasing across load conditions.

Switching performance is characterized by t_on = 295 ns, t_off = 730 ns, and f_T = 55 MHz under standard test conditions (V_CE = −10 V, I_C = −10 mA), enabling use in kHz-range SMPS and fast LED dimming control loops.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−150 V: Maximum safe blocking voltage with base open; enables direct interface with 100–120 VAC-derived rails.
I_C (continuous)	−1 A: Sustained collector current capability; supports LED chains drawing up to 1 A in constant-current mode.
V_CEsat	−300 mV @ I_C = −500 mA / I_B = −100 mA: Low conduction loss reduces heat generation in thermally constrained SOT23 layouts.
h_FE	70–300 @ −50 mA: Sufficient DC gain for simple resistor-biased switching without active driver circuitry.
R_th(j-a)	417 K/W on FR4: Thermal resistance defines power derating-P_tot drops to ~150 mW at 75 °C ambient.
f_T	55 MHz: Transition frequency confirms suitability for switching above 100 kHz with controlled rise/fall times.

Pinout & Package

SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, FR4-compatible footprint per Fig. 14.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Current-controlled input node; requires negative drive relative to emitter to turn on PNP device.
2	Emitter (E)	High-side reference terminal; connects to positive rail in high-side switch configurations.
3	Collector (C)	Load-switching output node; sinks current from load to ground when active.

Key Features

Feature	Design Value
High-voltage blocking	−150 V V_CEO enables direct use in 100–120 VAC-derived LED backlight supplies without cascaded devices.
Low saturation voltage	V_CEsat ≤ −300 mV at 500 mA ensures <150 mW conduction loss, critical for thermal management in sealed modules.
Robust thermal rating	150 °C max junction temperature and defined R_th(j-sp) = 70 K/W support solder-point thermal path design on industrial PCBs.
Fast switching	t_off = 730 ns allows PWM dimming up to 10 kHz with minimal dead-time overhead in LED drivers.

Applications

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
PBHV8115TLH	NPN complement; +150 V V_CEO, +1 A I_C, +300 mV V_CEsat; requires inverted drive logic.	Used in low-side switching topologies where emitter ties to ground; not drop-in for high-side PNP placement.	Select when circuit topology permits NPN configuration and ground-referenced load switching.
ZTX951	−120 V V_CEO, −1 A I_C, −500 mV V_CEsat (typ), TO-92 package; higher V_CEsat and larger footprint.	Legacy through-hole alternative; lacks SOT23 space efficiency and thermal performance on FR4.	Choose only for prototyping or legacy board rework where SMT assembly is unavailable.

Compared with PBHV8115TLH and ZTX951, PBHV9115TLHR delivers superior high-side switching efficiency due to its −150 V rating and −300 mV V_CEsat in SOT23, enabling smaller thermal pads, higher power density, and direct compatibility with 100 V-class LED and SMPS designs.

FAQ

What is the maximum safe operating voltage for PBHV9115TLHR?

The absolute maximum collector-emitter voltage (V_CEO) is −150 V with base open, and collector-base voltage (V_CB0) is −200 V. Operation beyond these values risks permanent breakdown. Designers must maintain ≥20 % voltage margin in transient-prone circuits like SMPS flybacks.

Can PBHV9115TLHR be driven directly by a 3.3 V microcontroller GPIO?

No-PBHV9115TLHR is a PNP transistor requiring negative base-emitter bias to turn on. A 3.3 V GPIO cannot sink sufficient current into the base without an external level-shifting stage (e.g., NPN pre-driver or dedicated gate driver IC) to pull the base below emitter potential.

How does thermal performance differ between FR4 and metal-core PCB mounting?

Data sheet R_th(j-a) = 417 K/W and R_th(j-sp) = 70 K/W assume standard FR4 with single-sided copper. Metal-core PCBs reduce R_th(j-a) significantly-typically to 100–200 K/W-but require validated solder pad layout and thermal vias; no official characterization is provided for non-FR4 substrates.

Is PBHV9115TLHR qualified for automotive applications?

No-per Revision History v.3 (20241009), PBHV9115TLHR is explicitly marked non-automotive qualified. Nexperia offers separate −Q automotive-grade variants (e.g., PBHV9115TLHQ); this part is intended for industrial, consumer, and commercial equipment only.
