Product details

Overview

PBHV8115T-QR from Nexperia is a 150 V, 1 A NPN high-voltage low-V_CEsat transistor in SOT23 package, designed for switching applications requiring high breakdown voltage and minimal conduction loss. It delivers V_CEsat = 225–350 mV at I_C = 100 mA / I_B = 10 mA, h_FE = 100–250 at I_C = 50 mA, and is AEC-Q101 qualified for automotive LED drivers and HID front lighting.

For engineers reviewing the PBHV8115T-QR datasheet, PBHV8115T-QR pinout, PBHV8115T-QR application, or PBHV8115T-QR equivalent, key selection criteria include verified V_CEO = 150 V rating, low saturation voltage under pulsed 1 A load, thermal resistance R_th(j-sp) = 70 K/W, and SOT23 footprint compatibility with automated SMT assembly.

Technical Context

This NPN bipolar junction transistor operates as a high-voltage saturated switch with collector-base voltage rating of 400 V and emitter-base voltage limit of 6 V. Its DC current gain remains ≥50 at I_C = 1 A (pulsed), supporting robust base drive design in automotive power control circuits.

Switching performance is characterized by t_on = 572 ns, t_off = 2230 ns, and f_T = 30 MHz - enabling use in medium-frequency SMPS and fast-response motor management circuits where low storage time (t_s = 1530 ns) reduces switching losses.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	150 V - maximum open-base collector-emitter blocking voltage; enables direct interface with 120 V DC bus or HID lamp ignition circuits
I_C	1 A continuous - supports sustained LED chain current or automotive hook-switch loads without derating at T_amb ≤ 75 °C
V_CEsat	225–350 mV at I_C = 100 mA / I_B = 10 mA - minimizes conduction loss and self-heating in high-duty-cycle switching
h_FE	100–250 at V_CE = 10 V, I_C = 50 mA - ensures stable base current design margin across temperature (−55 to +150 °C)
R_th(j-sp)	70 K/W - junction-to-solder-point thermal resistance on FR4 PCB; enables predictable thermal design without heatsink
f_T	30 MHz - transition frequency at V_CE = 10 V, I_C = 10 mA; supports stable operation up to ~5 MHz switching in practical SMPS designs
t_off	2230 ns - turn-off time under defined test conditions; determines minimum achievable PWM dead time in motor gate drivers

Pinout & Package

SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, single-sided copper FR4 mounting.

Pin/Terminal	Circuit Role	Design Meaning
1	Base (B)	Control input requiring 10–20 mA DC or pulsed drive to saturate transistor at 1 A collector current
2	Emitter (E)	Common reference node; connected to ground or low-side return path in high-side switch configurations
3	Collector (C)	High-voltage output terminal; rated for 150 V blocking and 1 A continuous conduction with <350 mV drop

Key Features

Feature	Design Value
AEC-Q101 qualification	Validated for automotive underhood environments per stress test standard; eliminates need for additional reliability screening
Low V_CEsat at high I_C	33–50 mV at I_C = 100 mA / I_B = 20 mA - reduces power dissipation by >40% vs. standard NPNs in same package
High V_CBO	400 V collector-base rating - provides margin against voltage transients in inductive load switching (e.g., solenoids, motors)
Thermal performance	R_th(j-sp) = 70 K/W - allows 300 mW total dissipation at ≤75 °C ambient without thermal derating on standard PCB
Small SMT footprint	SOT23 outline with 1.9 mm pitch - compatible with high-density layouts and standard pick-and-place equipment

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
PHV8115T-Q	Same die, non-automotive grade; lacks AEC-Q101 qualification and extended temperature validation	Restricted to industrial or consumer-grade lighting where automotive reliability not required	Select only if cost sensitivity outweighs automotive compliance needs and full lifecycle traceability is not mandated
PBHV9115T-Q	PNP complement with identical V_CEO, I_C, and V_CEsat; pinout mirrored (C/B/E → E/B/C)	Used in high-side switching or complementary push-pull stages where sourcing current is required	Choose when circuit topology demands PNP configuration or dual-transistor matched pair for balanced drive

Compared with PHV8115T-Q, PBHV8115T-QR adds AEC-Q101 validation and tighter parametric screening for automotive use; versus PBHV9115T-Q, it provides NPN polarity essential for low-side switching topologies with grounded emitter return paths.

FAQ

What is the maximum allowable junction temperature for PBHV8115T-QR?

The absolute maximum junction temperature (T_j) is 150 °C, as specified in the Limiting Values table. Operation at this temperature requires strict adherence to the power derating curve in Figure 1 - total power dissipation must be reduced linearly above 25 °C ambient, reaching zero at 75 °C ambient for continuous 300 mW rating on standard FR4 PCB.

Is PBHV8115T-QR suitable for linear (analog) amplification applications?

No - PBHV8115T-QR is optimized for saturated switching, not linear amplification. Its h_FE drops to 10–30 at I_C = 1 A, and V_CEsat is specified only under switching conditions. The device lacks guaranteed linearity, gain flatness, or noise performance required for analog signal amplification.

How does the SOT23 package affect thermal performance in high-current operation?

On standard FR4 PCB with single-sided copper, the SOT23 package delivers R_th(j-sp) = 70 K/W to solder point and R_th(j-a) = 417 K/W to ambient. At 1 A and 350 mV V_CEsat, power dissipation is 350 mW - resulting in ~25 °C junction-to-ambient rise, well within safe limits below 75 °C ambient.

Can PBHV8115T-QR replace older-generation NPN transistors like BC817 in automotive designs?

Only with circuit redesign. PBHV8115T-QR has higher V_CEO (150 V vs. 45 V), lower V_CEsat, and AEC-Q101 qualification - but its h_FE profile and switching times differ significantly. Direct substitution risks overdrive, timing mismatch, or thermal instability without validation of base drive network and layout.
