Product details

Overview

PBHV8115TLHR 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 ≤ 350 mV at I_C = 1 A / I_B = 200 mA, h_FE = 70–300 at I_C = 50 mA, and supports peak current up to 2 A - used in LED chain drivers and SMPS primary-side switching.

For engineers reviewing the PBHV8115TLHR datasheet, PBHV8115TLHR pinout, PBHV8115TLHR application, or PBHV8115TLHR equivalent, key selection criteria include verified V_CEO = 150 V rating, low saturation voltage under high-current pulsed conditions, thermal resistance R_th(j-sp) = 70 K/W, and SOT23 footprint compatibility with automated assembly.

Technical Context

This NPN bipolar junction transistor operates as a high-voltage saturated switch with guaranteed V_CEO = 150 V and V_CBO = 400 V, enabling use in 100–120 V DC bus or flyback clamp circuits. Its low V_CEsat (≤350 mV) and high h_FE (min 70 at 50 mA) reduce drive current demand and conduction losses in continuous and pulsed switching.

Thermal performance is defined for FR4 PCB mounting: R_th(j-a) = 417 K/W (free air), R_th(j-sp) = 70 K/W (solder point), supporting 300 mW P_tot at T_amb ≤ 25 °C. Switching parameters include t_on = 575 ns and t_off = 2230 ns under specified test conditions (V_CC = 6 V, I_C = 0.5 A).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	150 V - enables direct switching of 100–120 V DC rails without external snubbers
I_C (continuous)	1 A - supports sustained load current in LED backlight and power management stages
V_CEsat @ I_C/I_B = 1 A/200 mA	≤350 mV - reduces power dissipation to ≤350 mW during saturation, easing thermal design
h_FE @ I_C = 50 mA	70–300 - ensures reliable base drive margin across temperature and process variation
R_th(j-sp)	70 K/W - allows 2.1 °C rise per 30 mW at solder point, critical for compact SOT23 thermal layout
f_T	30 MHz - sufficient for <1 MHz SMPS switching and LED dimming control bandwidth
t_off	2230 ns - defines minimum off-time in high-frequency PWM operation with fixed dead time

Pinout & Package

SOT23 plastic surface-mounted package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, single-sided copper FR4 mounting. Thermal pad not present; standard footprint per Fig. 14 (reflow) and Fig. 15 (wave).

Pin/Terminal	Circuit Role	Design Meaning
1 - B	Base	Control input requiring ≥200 mA peak drive for full saturation at 1 A collector current
2 - E	Emitter	Reference node for base drive and current return path; connected to ground or low-side return
3 - C	Collector	High-voltage switched output node; rated for 150 V DC and 200 V peak transient (V_CESM)

Key Features

Feature	Design Value
High-voltage blocking	V_CBO = 400 V provides margin against voltage spikes in inductive switching circuits
Low saturation voltage	V_CEsat ≤ 350 mV at I_C = 1 A reduces conduction loss by >40% vs. standard 1 A transistors
Robust thermal interface	R_th(j-sp) = 70 K/W enables direct thermal coupling to PCB copper, avoiding heatsinks in space-constrained designs
Wide operating temperature	T_amb = −55 °C to +150 °C supports industrial and outdoor LED driver deployments
Fast turn-off capability	t_off = 2230 ns allows stable operation up to ~200 kHz PWM with controlled dead time

Applications

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
ZTX653STZ	V_CEO = 120 V, V_CEsat = 400 mV @ 1 A, h_FE = 100–300, SOT23	Lower voltage rating limits use to ≤100 V systems; higher V_CEsat increases conduction loss by ~14%	Select when 120 V max is sufficient and tighter h_FE distribution is required
BCX56-16,115	V_CEO = 80 V, V_CEsat = 500 mV @ 1 A, h_FE = 100–250, SOT89	Lower voltage and higher saturation voltage; larger SOT89 package increases board area and thermal resistance	Choose only if legacy SOT89 footprint must be retained and voltage requirements are ≤80 V

Compared with ZTX653STZ and BCX56-16,115, PBHV8115TLHR uniquely combines 150 V blocking, sub-350 mV saturation, and SOT23 size - enabling higher-voltage operation without package or thermal trade-offs.

FAQ

What is the maximum allowable base current for PBHV8115TLHR?

The absolute maximum peak base current is 400 mA (single pulse, t_p ≤ 1 ms), per Table 5. For continuous operation, base current must be limited to ensure junction temperature remains ≤150 °C - typical design uses I_B = 200 mA to achieve full saturation at I_C = 1 A while maintaining safe thermal margin on FR4 PCB.

Can PBHV8115TLHR replace a MOSFET in low-frequency switching applications?

Yes, but only where gate drive simplicity and cost outweigh efficiency needs. PBHV8115TLHR requires significant base current (200 mA) versus MOSFET gate charge, increasing driver complexity. Its 350 mV V_CEsat yields lower conduction loss than many small-signal MOSFETs above 10 V V_DS, but switching loss is higher due to slower t_off (2230 ns).

Is PBHV8115TLHR qualified for automotive applications?

No. Per Revision History (Table 8), PBHV8115TLHR v.3 explicitly states "non-automotive qualification." It lacks AEC-Q101 stress testing and automotive-grade screening. For automotive use, Nexperia offers the -Q qualified variant PBHV8115TLHQ, which undergoes extended temperature cycling and humidity testing.

How does thermal derating affect power handling on standard FR4?

Per Figure 1, P_tot drops linearly above 25 °C ambient: at 75 °C, derated power is ~150 mW; at 125 °C, it falls to ~30 mW. This reflects R_th(j-a) = 417 K/W. For sustained 1 A operation, PCB copper area and airflow must be optimized - or use pulsed operation below 2 A peak with duty cycle <2% to stay within thermal limits.
