Product details

Overview

PBHV8118T,215 from Nexperia is an 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 IC = 100 mA / IB = 20 mA. It serves as a high-efficiency switching element in LED chain drivers and telecom hook switches where high breakdown voltage and minimal conduction loss are critical.

For engineers reviewing the PBHV8118T,215 datasheet, PBHV8118T,215 pinout, PBHV8118T,215 application, or PBHV8118T,215 equivalent, this device is selected for high-voltage DC-DC control stages, automotive power management subsystems, and space-constrained LED backlighting circuits requiring stable low-saturation operation up to 150 °C junction temperature.

Technical Context

This NPN transistor operates with open-base V_CEO = 180 V and V_CBO = 400 V, enabling use in off-line switch-mode power supplies and telecom line interface circuits. Its h_FE ranges from 50–250 (IC = 50 mA to 0.5 A), supporting robust base-driven switching across wide current loads.

Thermal resistance R_th(j-a) is 417 K/W on FR4 PCB, and R_th(j-sp) is 70 K/W - confirming suitability for thermally constrained SMT layouts. Switching times (t_on = 572 ns, t_off = 2060 ns) reflect optimized charge storage for medium-speed power control.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	180 V - supports direct connection to 120 VAC rectified rails without external snubbing
I_C	1 A continuous - enables single-transistor drive of multi-LED strings or telecom load switching
V_CEsat	40 mV typ. @ IC = 100 mA, IB = 20 mA - reduces conduction loss to <4 mW at rated current
h_FE	100–250 @ IC = 50 mA - ensures reliable saturation with moderate base drive in industrial controls
f_T	30 MHz - sufficient for SMPS operation up to ~500 kHz with margin for layout parasitics
R_th(j-a)	417 K/W - defines thermal derating to 150 mW at 75 °C ambient on standard FR4
t_off	2060 ns - limits minimum switching frequency to ~485 kHz for hard-switched topologies

Pinout & Package

SOT23 (TO-236AB) plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch, tin-plated terminations compatible with standard reflow profiles.

Pin/Terminal	Circuit Role	Design Meaning
1 - B	Base	Control input requiring ≥20 mA peak drive for full saturation at 100 mA collector load
2 - E	Emitter	Common reference node; connects directly to ground or low-side return path in switching configurations
3 - C	Collector	High-voltage output node; rated for 180 V blocking and 1 A continuous conduction in pulsed or DC mode

Key Features

Feature	Design Value
High-voltage capability	V_CBO = 400 V enables use in flyback primary-side switching with 2× safety margin over 180 V rail
Low V_CEsat	40 mV typ. minimizes I²R losses in battery-powered LED modules operating at 100–500 mA
High h_FE at high I_C	h_FE ≥ 50 @ IC = 0.5 A ensures stable gain in automotive power management without excessive base current
Small SOT23 footprint	2.9 mm × 1.3 mm area allows placement in dense LED driver PCBs with <1.5 mm clearance to adjacent components
150 °C max T_j	Enables operation in under-hood automotive modules without active cooling or derating below 1 A

Applications

LED Chain Driver

LCD Backlighting

Use Scenario: Driving 12–24 V LED chains in signage or architectural lighting with constant-current regulation via PWM dimming.

IC Role / Device Role / Timing Role: Low-side switch controlling LED current path; handles repetitive 1–10 kHz PWM with <2 µs turn-off delay.

Use Value: 40 mV V_CEsat limits power dissipation to ≤40 mW per LED string, reducing thermal design burden in sealed enclosures.

Use Scenario: Boost converter switching element in portable LCD TV backlight inverters operating from 3.3–5 V supply.

IC Role / Device Role / Timing Role: Primary-side NPN switch in discrete boost topology; operates at 200–500 kHz with fixed duty cycle.

Use Value: 30 MHz f_T and 2.06 µs t_off support stable regulation at 500 kHz while maintaining >85% efficiency.

Automotive Power Management

Hook Switch for Wired Telecom

Use Scenario: Load switching for 12 V accessory circuits (e.g., HVAC blower control, seat heater enable) in passenger vehicles.

IC Role / Device Role / Timing Role: High-side or low-side power switch controlled by microcontroller GPIO; withstands load dump transients up to 180 V.

Use Value: 180 V V_CEO eliminates need for external transient voltage suppressors in ISO 7637-2 compliant designs.

Use Scenario: Ringing generator switch in VoIP analog telephone adapters (ATAs) interfacing POTS lines.

IC Role / Device Role / Timing Role: High-voltage switch connecting AC ringing signal (90 V RMS, 20 Hz) to telephone line; blocks reverse polarity during on-hook state.

Use Value: 400 V V_CBO rating ensures safe operation during line fault conditions including lightning-induced surges.

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
PHB110NQ03LT	N-channel MOSFET (30 V V_DS, 110 A); gate-driven, no base current required	Lower voltage rating limits use to ≤24 V systems; unsuitable for 120 VAC-derived rails	Select only for low-voltage, high-current DC loads where gate drive is available and V_DS margin is sufficient
BCP56-10,215	NPN transistor (80 V V_CEO, 1 A, SOT223); higher V_CEsat (300 mV typ.)	Insufficient voltage headroom for LED drivers on 100 VDC bus or telecom line interfaces	Acceptable only in ≤60 V automotive or industrial control where saturation loss is non-critical

Compared with PHB110NQ03LT and BCP56-10,215, PBHV8118T,215 uniquely balances 180 V blocking, 40 mV saturation, and SOT23 size - making it the sole option among these three for compact, high-voltage, low-loss bipolar switching in LED and telecom applications.

FAQ

What is the maximum allowable base current for PBHV8118T,215?

The absolute maximum peak base current (I_BM) is 400 mA per datasheet Table 5. For reliable long-term operation, sustained base current should not exceed 100 mA, as validated in V_BEsat test conditions (IC = 0.5 A, IB = 100 mA). Exceeding 400 mA risks metallization failure or bond wire lift.

Can PBHV8118T,215 be used in automotive applications?

No - the datasheet revision history explicitly states this part was changed to non-automotive qualification in v.3 (20241008). It lacks AEC-Q101 stress testing and automotive-grade screening. For automotive use, Nexperia recommends its -Q qualified alternatives such as PBHV8118T-Q.

What is the thermal resistance from junction to solder point (R_th(j-sp)) and how is it applied?

R_th(j-sp) is 70 K/W, measured from die junction to solder joint on FR4 PCB with standard footprint. This value is used to calculate localized junction temperature rise above board temperature (T_j = T_board + P_diss × 70), critical for reliability validation in thermally isolated PCB zones.

Does PBHV8118T,215 support linear (analog) operation or only switching?

It supports both modes: h_FE is specified across IC = 50 mA to 500 mA, and V_CEsat is characterized at multiple I_C/I_B ratios. However, its low R_CEsat and fast switching make it optimized for saturated switching; linear use requires careful thermal management due to limited SOA at high V_CE.
