Product details

Overview

PBHV8118T-QR from Nexperia is an AEC-Q101-qualified NPN high-voltage low-V_CEsat transistor in SOT23 package, rated for 180 V V_CEO, 1 A continuous collector current, and 40 mV typical V_CEsat at I_C = 100 mA / I_B = 20 mA. It serves as a robust switching element in automotive LED drivers and SMPS primary-side control circuits.

For engineers reviewing the PBHV8118T-QR datasheet, PBHV8118T-QR pinout, PBHV8118T-QR application, or PBHV8118T-QR equivalent, this device is selected for high-voltage linear/switching operation where low saturation loss, thermal stability up to 150 °C junction temperature, and automotive-grade reliability are required.

Technical Context

This discrete NPN transistor operates with open-base V_CEO = 180 V and V_CBO = 400 V, enabling use in 100–150 V DC bus switching applications. Its h_FE ranges from 50–250 (I_C = 50 mA to 0.5 A), supporting both analog gain and saturated-switch biasing modes.

Thermal resistance R_th(j-a) = 417 K/W on FR4 PCB defines its power handling limit: P_tot = 300 mW at T_amb ≤ 25 °C, derating linearly above 25 °C per Fig. 1. Switching performance includes t_on = 572 ns and t_off = 2060 ns under specified test conditions (V_CC = 6 V, I_C = 0.5 A).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	180 V - Maximum safe collector-emitter voltage with base open; enables use in 120–150 V DC supply rails.
I_C (continuous)	1 A - Continuous collector current rating; supports LED chain drivers up to ~10 W at 100 V.
V_CEsat @ I_C=100 mA	40 mV typ - Low conduction loss reduces heat generation and improves efficiency in PWM-driven loads.
h_FE @ I_C=0.5 A	50–100 - Sufficient DC gain to drive with modest base current (e.g., 5–10 mA) in saturated switch mode.
R_th(j-a)	417 K/W - Thermal resistance on standard FR4 PCB; limits usable power to ~150 mW at 75 °C ambient.
f_T	30 MHz - Transition frequency confirms suitability for medium-speed switching (≤500 kHz SMPS).
C_c	5.7 pF - Collector capacitance impacts high-frequency turn-off behavior and EMI in fast-switching nodes.

Pinout & Package

3	Collector (C)	High-voltage output node; handles up to 180 V and 1 A load current in switching mode.

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
ZXTN2012ZTA	V_CEO = 120 V, V_CEsat = 120 mV @ I_C=1 A - Lower voltage rating, higher saturation loss.	Suitable only for ≤100 V DC bus; less efficient in high-voltage LED drivers.	Select when cost sensitivity outweighs voltage margin and efficiency needs.
BCX56-16Q	V_CEO = 80 V, h_FE = 100–250 @ I_C=150 mA - Not rated for automotive temp range; no AEC-Q101 qualification.	Restricted to non-automotive industrial or consumer applications.	Choose only for non-automotive designs where qualification is not required.

Compared with ZXTN2012ZTA and BCX56-16Q, PBHV8118T-QR delivers superior high-voltage capability (180 V), lower conduction loss (40 mV), and guaranteed automotive qualification-making it the sole option for AEC-compliant 100+ V switching in harsh environments.

FAQ

Is PBHV8118T-QR pin-compatible with standard SOT23 NPN transistors?

Yes - PBHV8118T-QR uses standard SOT23 pinout (1=Base, 2=Emitter, 3=Collector), matching industry-standard layout footprints including JEDEC TO-236AB. No PCB redesign is needed when upgrading from legacy SOT23 NPN switches with identical pin assignment.

What is the maximum allowable base current for continuous operation?

The peak base current rating is 400 mA (single pulse, t_p ≤ 1 ms), but continuous base current must be limited to ensure junction temperature stays within 150 °C. At I_C = 1 A and h_FE = 50, I_B ≈ 20 mA is sufficient for saturation; sustained I_B > 50 mA risks thermal overload without forced cooling.

Can PBHV8118T-QR replace MOSFETs in 100 V switching applications?

It can serve as a cost-effective alternative in low-frequency (<100 kHz), moderate-current (<1 A) linear or saturated switching roles where gate drive complexity and MOSFET threshold variation are concerns. However, it lacks the zero-gate-drive advantage and has higher drive current demand than MOSFETs.

Does PBHV8118T-QR require external snubber circuitry in inductive load switching?

Yes - while its 400 V V_CBO provides margin against inductive kickback, fast-switching inductive loads (e.g., relays, solenoids) should include a reverse-biased flyback diode across the load. A small RC snubber may further reduce voltage overshoot during turn-off in high-dI/dt scenarios.
