Product details
Overview
NXP3875GR from Nexperia is an AEC-Q101-qualified NPN general-purpose transistor in SOT23 (TO-236AB) package, rated for 50 V VCEO, 150 mA IC, and DC current gain (hFE) of 200–400 at VCE = 6 V / IC = 2 mA. It serves as a compact, thermally efficient switching and amplification device in automotive body control modules, industrial sensor interfaces, and consumer power management circuits.
For engineers reviewing the NXP3875GR datasheet, NXP3875GR pinout, NXP3875GR application, or NXP3875GR equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, automotive-grade reliability context, and real-world use cases in low-voltage discrete switching and linear amplification.
Technical Context
This NPN bipolar junction transistor operates with a maximum collector-base voltage of 60 V and emitter-base voltage of 5 V, supporting robust biasing in 5–24 V rail systems. Its 250 mV VCEsat at IC = 100 mA / IB = 10 mA enables low-loss switching in load drivers and signal-level amplification stages.
Thermal resistance Rth(j-a) is 625 K/W on FR4 PCB with standard footprint, and transition frequency fT reaches 80 MHz at VCE = 10 V / IC = 1 mA / f = 100 MHz - confirming suitability for audio-frequency and low-speed digital signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage under open-base condition; defines upper rail limit for switch operation. |
| IC | 150 mA continuous - Absolute max collector current; supports driving LEDs, relays, and small solenoids. |
| hFE | 200–400 - High DC current gain at 2 mA collector current; reduces base drive requirements in low-power logic interfacing. |
| VCEsat | 250 mV @ IC=100 mA/IB=10 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications. |
| fT | 80 MHz - Transition frequency confirms usable bandwidth up to ~10 MHz for small-signal amplification and pulse shaping. |
| Rth(j-a) | 625 K/W - Thermal resistance on standard FR4 PCB; informs derating above 25 °C ambient for sustained 150 mA operation. |
Pinout & Package
Package: SOT23 (TO-236AB), surface-mount plastic package with 3 leads, 1.9 mm × 1.1 mm footprint, 0.95 mm height, and standard 0.95 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Current-controlled input node; requires 10 mA base drive for full 100 mA collector conduction. |
| 2 | Emitter | Common reference terminal; tied to ground or low-side return path in most switching configurations. |
| 3 | Collector | Output current sink; connects to load (e.g., LED anode, relay coil) referenced to positive supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood and cabin applications per stress test standard for discrete semiconductors. |
| High hFE bin (200–400) | Reduces required base drive current by ≥2× vs. standard 120–240 hFE transistors, easing microcontroller GPIO loading. |
| Low VCEsat (250 mV) | Enables <15 mW conduction loss at 100 mA, critical for thermally constrained PCB layouts and battery-powered devices. |
| SOT23 footprint compatibility | Matches industry-standard 3-pin SMD layout; supports automated placement and reflow soldering without adapter. |
Applications
| Automotive Body Control Unit | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving 12 V incandescent dome lights and door lock actuators in vehicle interior modules. IC Role / Device Role / Timing Role: NPN switch controlling high-side grounded loads via microcontroller GPIO.

| Consumer Power Management | IoT Peripheral Interface |
Use Scenario: Enabling/disabling USB-C port power delivery paths in portable docking stations. IC Role / Device Role / Timing Role: Low-side switch controlling PMIC enable inputs or LDO bias rails.

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B,215 | Same SOT23 package; hFE = 200–450, but not AEC-Q101 qualified; VCEO = 45 V. | Limited to industrial/commercial use; unsuitable for automotive safety-critical subsystems. | Select when cost sensitivity outweighs automotive qualification requirement. |
| MMBT3904LT1G | hFE = 100–300; VCEO = 40 V; Rth(j-a) = 500 K/W; AEC-Q101 qualified. | Lower voltage rating restricts use to ≤36 V systems; higher thermal resistance demands tighter layout control. | Choose where lower hFE tolerance is acceptable and 40 V operation suffices. |
Compared with BC847B,215 and MMBT3904LT1G, NXP3875GR uniquely combines AEC-Q101 qualification, 50 V rating, and 200–400 hFE in one SOT23 device - making it the only option meeting automotive body electronics requirements without derating or redesign.

FAQ
Is NXP3875GR pin-compatible with BC847 series transistors?
Yes - NXP3875GR uses standard SOT23 pinout (1=Base, 2=Emitter, 3=Collector), matching BC847, BC848, and MMBT3904 families. Layout reuse is possible, but verify VCEO (50 V vs. 45 V/40 V) and hFE distribution before drop-in replacement in automotive designs.
What is the maximum allowable ambient temperature for continuous 150 mA operation?
At 150 mA, power dissipation reaches 22.5 mW (assuming 150 mV VCEsat). With Rth(j-a) = 625 K/W, junction temperature rise is ~14 °C - allowing full-rated current up to +136 °C ambient before hitting Tj = 150 °C limit. Derating begins above 125 °C per Figure 1.
Does NXP3875GR support pulsed operation beyond 150 mA?
Yes - peak collector current ICM is rated at 200 mA for single pulses ≤1 ms. This enables short-duration surge handling in motor commutation snubbers or LED strobe drivers, provided duty cycle and thermal mass prevent cumulative heating.
How does the 200–400 hFE bin affect circuit design?
This tight hFE range reduces base resistor tolerance sensitivity: for 100 mA IC, base current varies only from 250 µA to 500 µA - enabling simpler, more predictable bias networks versus wider-gain transistors that require feedback or trimming.
