Product details
Overview
BCP68-25,135 from Nexperia is a medium-power NPN bipolar junction transistor in SOT223 (SC-73) package, rated for 20 V VCEO, 2 A continuous collector current, and 1.35 W power dissipation on 6 cm² copper pad. It delivers hFE = 160–375 at VCE = 1 V and IC = 500 mA, with low VCE(sat) ≤ 0.6 V at IC = 2 A / IB = 200 mA - used in MOSFET gate driving and linear voltage regulation circuits.
For engineers reviewing the BCP68-25,135 datasheet, BCP68-25,135 pinout, BCP68-25,135 application, or BCP68-25,135 equivalent, key selection criteria include verified DC current gain binning (hFE ≥ 160), thermal resistance Rth(j-a) = 93 K/W under optimized PCB layout, and dual-collector pin configuration enabling high-current switching in compact SMT designs.
Technical Context
The BCP68-25,135 operates as a medium-power NPN switch with open-base VCEO = 20 V and pulsed ICM = 3 A, supporting robust low-side switching in battery-powered systems. Its hFE binning (160–375) ensures predictable base drive requirements across production lots.
Thermal performance is defined by three mounting conditions: standard footprint (Rth(j-a) = 192 K/W), 1 cm² collector pad (125 K/W), and 6 cm² pad (93 K/W). The device exhibits fT = 40–170 MHz and Cc = 22 pF, confirming suitability for moderate-speed switching up to ~100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 20 V - Maximum safe collector-emitter voltage with base open; defines upper rail limit in low-side switch applications. |
| IC | 2 A - Continuous DC collector current rating; supports sustained load switching in power management blocks. |
| hFE | 160–375 at VCE = 1 V, IC = 500 mA - Confirmed current gain bin ensuring stable base drive design for MOSFET drivers. |
| VCE(sat) | ≤ 0.6 V at IC = 2 A, IB = 200 mA - Low saturation voltage minimizes conduction loss in linear regulators and switching nodes. |
| Ptot | 1.35 W at Tamb ≤ 25 °C with 6 cm² copper pad - Enables higher power handling than standard SOT223 without heatsink. |
| fT | 40–170 MHz - Transition frequency confirms usable bandwidth for PWM gate driving up to ~100 kHz with margin. |
| Rth(j-a) | 93 K/W - Thermal resistance with 6 cm² collector pad; enables thermal design for 1.35 W dissipation at ΔT = 125 °C. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with four leads: two collector terminals (pins 2 and 4), one base (pin 1), and one emitter (pin 3); integrated heatsink tab connected to collector for enhanced thermal transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input requiring IB ≤ 0.4 A; drives transistor into saturation with IC/IB ≤ 10. |
| 2 | Collector | Main current-carrying terminal; electrically tied to pin 4 and thermal pad for parallel current path and heat sinking. |
| 3 | Emitter | Reference node for output stage; connects to ground or low-side return path in switching configurations. |
| 4 | Collector | Second collector terminal; shares internal connection with pin 2 to reduce bond wire inductance and improve current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector configuration | Reduces effective on-resistance and thermal impedance by paralleling internal collector paths in SOT223 footprint. |
| High hFE bin (160–375) | Enables lower base drive current in MOSFET driver stages, reducing MCU GPIO loading and PCB trace losses. |
| 1.35 W power dissipation | Supports higher continuous current in linear regulator pass elements without external heatsink when using 6 cm² copper area. |
| Low VCE(sat) ≤ 0.6 V | Minimizes voltage drop and power loss in low-side switch applications operating near 2 A load currents. |
| FR4-compatible reflow footprint | Standardized 7.3 mm × 6.7 mm land pattern (Fig. 10) ensures manufacturable solder joint reliability in high-volume SMT assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium-power transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP56-16,115 | VCEO = 80 V, IC = 1 A, hFE = 100–250, SOT223 package | Higher voltage rating but lower current capacity; unsuitable for 2 A continuous loads | Select only if system requires >20 V blocking with reduced current demand. |
| ZTX653STZ | VCEO = 60 V, IC = 3 A, hFE = 100–300, SOT89 package | Higher current and voltage ratings but different thermal pad layout and pinout (3-pin) | Choose when board space allows SOT89 and higher VCEO/IC margins are required. |
Compared with BCP68-25,135, BCP56-16,115 trades current capability for higher voltage headroom, while ZTX653STZ offers greater current and voltage ratings but requires PCB redesign due to SOT89 footprint and single-collector configuration.

FAQ
What is the guaranteed hFE range for BCP68-25,135 at IC = 500 mA?
The BCP68-25,135 is binned to guarantee hFE = 160–375 when measured at VCE = 1 V and IC = 500 mA under pulsed conditions (tp ≤ 300 μs, duty cycle ≤ 0.02). This bin ensures predictable base current requirements for gate-driving and regulator applications without gain variation fallback.
Can BCP68-25,135 replace BCP68-16 in existing designs?
No - BCP68-25,135 and BCP68-16 differ in hFE binning: BCP68-25 guarantees minimum hFE = 160, while BCP68-16 guarantees minimum hFE = 85. Substituting may increase required base drive current by up to 2×, risking insufficient saturation in high-current switching nodes.
What is the maximum allowable PCB copper area for thermal optimization?
The 1.35 W power dissipation rating assumes a 6 cm² copper pad connected to the collector terminals (pins 2 and 4) on a single-sided FR4 board. Increasing pad area beyond 6 cm² yields diminishing thermal returns; no derating data is provided for larger pads in the official datasheet Rev. 9.
Does BCP68-25,135 support wave soldering?
Yes - Nexperia provides a dedicated wave soldering footprint (Fig. 11) for SOT223, specifying 1.9 mm lead spacing, 6.2 mm body length, and preferred transport direction aligned with pin 1–3 axis. Thermal profiling must respect peak temperature ≤ 260 °C for ≤ 5 seconds per IPC-J-STD-020.
