Product details
Overview
BCP68-25,115 from Nexperia is an NPN medium power transistor in SOT223 (SC-73) package, rated for 20 V VCEO, 2 A continuous collector current, and 1.35 W total power dissipation on 6 cm² copper pad - used as low-side switch in linear voltage regulators and MOSFET drivers.
For engineers reviewing the BCP68-25,115 datasheet, BCP68-25,115 pinout, BCP68-25,115 application, or BCP68-25,115 equivalent, key selection factors include hFE binning (160–375 at IC = 500 mA), thermal resistance (93 K/W with 6 cm² pad), saturation voltage (≤0.6 V at IC = 2 A / IB = 200 mA), and SOT223 dual-collector thermal design.
Technical Context
The BCP68-25,115 is a silicon NPN bipolar junction transistor optimized for medium-power switching and amplification. Its dual-collector (pins 2 and 4) configuration enhances thermal conduction to PCB copper, supporting sustained 2 A DC operation when mounted on ≥6 cm² tin-plated FR4.
It features a guaranteed DC current gain (hFE) range of 160–375 at VCE = 1 V and IC = 500 mA under pulsed conditions (tp ≤ 300 μs, duty cycle ≤ 0.02), with VCE(sat) ≤ 0.6 V at IC = 2 A / IB = 200 mA - enabling efficient low-side drive in battery-powered power management circuits.
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 (continuous) | 2 A - Continuous collector current rating; supports load switching up to ~24 W at 12 V with adequate heatsinking. |
| hFE (min/typ/max) | 160–375 at VCE = 1 V, IC = 500 mA - Tight gain bin ensures predictable base drive requirements in linear regulators and driver stages. |
| VCE(sat) | ≤0.6 V at IC = 2 A, IB = 200 mA - Low saturation voltage minimizes conduction loss and self-heating during high-current switching. |
| Ptot | 1.35 W at Tamb ≤ 25 °C with 6 cm² collector pad - Enables stable operation without external heatsink in space-constrained industrial PCBs. |
| Rth(j-a) | 93 K/W - Thermal resistance from junction to ambient with 6 cm² copper pad; enables ~14 °C/W effective cooling above ambient. |
| fT | 40–170 MHz - Transition frequency supports audio-frequency amplification and fast-switching (<100 ns rise time) in PWM-driven loads. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with four leads: pins 2 and 4 are internally connected collectors for enhanced thermal transfer to PCB copper; pin 1 is base; pin 3 is emitter. The package footprint requires 6 cm² copper area under collector pads for full 1.35 W power rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input terminal; requires ≥200 mA base drive for full 2 A collector conduction with guaranteed VCE(sat). |
| 2 | Collector | Primary high-current output terminal; electrically tied to pin 4; must be soldered to ≥6 cm² copper for rated power dissipation. |
| 3 | Emiter | Reference/return path for collector current; common connection point for emitter resistors in amplifier or current-sense configurations. |
| 4 | Collector | Secondary collector terminal; internally bonded to pin 2; provides redundant thermal path and mechanical stability in high-vibration environments. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-collector SOT223 thermal design | Enables 1.35 W power dissipation without external heatsink when mounted on 6 cm² FR4 copper pad. |
| High-current gain bin (BCP68-25) | hFE = 160–375 at IC = 500 mA ensures consistent base drive sizing across production lots. |
| Low VCE(sat) at high current | ≤0.6 V at IC = 2 A / IB = 200 mA reduces conduction loss by >30% vs. standard medium-power transistors. |
| Robust absolute maximum ratings | VCBO = 32 V, VEBO = 5 V, and Tj(max) = 150 °C support operation in noisy 24 V industrial rails. |
| Pulsed current capability | ICM = 3 A (1 ms pulse) allows brief surge handling in motor start-up or capacitor charging circuits. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |
|---|---|
|
Use Scenario: Pass transistor in adjustable 3-terminal linear regulators delivering up to 2 A output current. IC Role / Device Role / Timing Role: NPN series pass element controlling output voltage via base bias from error amplifier. Use Value: Low VCE(sat) (≤0.6 V) maintains <1.2 V dropout at 2 A, enabling regulation from 5 V input to 3.3 V output. |
Use Scenario: Gate driver stage for N-channel power MOSFETs in DC-DC converters and motor controllers. IC Role / Device Role / Timing Role: Medium-power NPN switch sourcing gate current during MOSFET turn-on. Use Value: 2 A IC rating supports fast gate charging of MOSFETs with Qg ≤ 50 nC at 100 kHz switching frequencies. |
| Low-Side Switches | Battery-Driven Devices |
|
Use Scenario: High-current load switch for solenoids, relays, or LED arrays in industrial control panels. IC Role / Device Role / Timing Role: Ground-referenced NPN switch controlled by microcontroller GPIO or logic-level signal. Use Value: Dual-collector thermal design sustains 2 A continuous current without derating in enclosed 60 °C ambient enclosures. |
Use Scenario: Power path control and battery discharge protection in portable medical monitors and handheld test equipment. IC Role / Device Role / Timing Role: Load switch isolating main battery from system during sleep mode or fault conditions. Use Value: VEBO = 5 V and low leakage (IEBO ≤ 100 nA) prevent unintended discharge through base-emitter junction during storage. |
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 |
|---|---|---|---|
| BCP56-10,115 | Lower hFE (63–160), same VCEO/IC, higher Rth(j-a) (125 K/W) | Less suitable for low-base-drive designs; requires larger copper area for same power handling | Select when cost sensitivity outweighs gain consistency and thermal performance. |
| ZTX653STZ | Higher VCEO (60 V), lower IC (1 A), TO-92 package | Not SMT-compatible; limited to <1 A continuous loads; unsuitable for 2 A regulator pass devices | Choose only for legacy through-hole designs requiring higher voltage margin and accepting reduced current capacity. |
Compared with BCP68-25,115, BCP56-10,115 trades gain and thermal performance for cost, while ZTX653STZ sacrifices SMT compatibility and current rating for higher breakdown voltage - making BCP68-25,115 optimal for modern 2 A SMT low-side switching where gain consistency and board-level thermal management are critical.

FAQ
What is the guaranteed hFE range for BCP68-25,115 at IC = 500 mA?
The BCP68-25,115 is binned to guarantee hFE = 160–375 at VCE = 1 V and IC = 500 mA under pulsed conditions (tp ≤ 300 μs, duty cycle ≤ 0.02), as confirmed in Table 4 of the Rev. 9 datasheet. This bin ensures predictable base current requirements across manufacturing lots.
Can BCP68-25,115 replace BCP68-16,115 in existing designs?
Yes - both share identical package, voltage/current ratings, and thermal characteristics, differing only in hFE bin (BCP68-16: 85–175). Designs using BCP68-16 may require increased base drive current to maintain saturation, but layout and thermal design remain fully compatible.
What PCB copper area is required to achieve the 1.35 W power rating?
A 6 cm² tin-plated copper pad connected to pins 2 and 4 (collectors) on FR4 PCB is required to achieve the full 1.35 W Ptot rating at Tamb ≤ 25 °C, per Table 5 footnote [3] and Figure 1 curve (3). Using smaller pads reduces allowable power linearly per the derating curves.
Is BCP68-25,115 qualified for automotive applications?
No - the Rev. 9 datasheet explicitly states this device is non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia offers the -Q qualified variants (e.g., BCP68-25Q,115), which undergo extended temperature cycling and humidity testing.
