Product details
Overview
BCP68,115 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. It delivers hFE = 85–375 at VCE = 1 V, IC = 500 mA, and supports linear voltage regulation and low-side switching in battery-powered industrial modules.
For engineers reviewing the BCP68,115 datasheet, BCP68,115 pinout, BCP68,115 application, or BCP68,115 equivalent, this device is selected for medium-power analog switching where thermal performance on FR4 PCBs, DC current gain consistency across temperature, and robust pulsed current handling (ICM = 3 A) are critical design constraints.
Technical Context
The BCP68,115 operates as a silicon NPN bipolar junction transistor optimized for linear and switching applications up to 20 V. Its base-emitter junction sustains 5 V reverse bias, while collector-base breakdown reaches 32 V - enabling safe operation in inductive load switching with flyback margin.
Thermal design relies on its junction-to-ambient resistance of 93 K/W when mounted on 6 cm² copper, and its fT = 40–170 MHz supports high-speed switching up to ~100 MHz under 50 mA IC, with VCE(sat) ≤ 0.6 V at IC = 2 A / IB = 200 mA.
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 designs. |
| IC | 2 A - Continuous DC collector current rating; sets maximum steady-state load drive capability. |
| hFE | 85–375 - DC current gain range at VCE = 1 V, IC = 500 mA; determines required base drive for saturation control. |
| Ptot | 1.35 W - Max power dissipation on FR4 PCB with 6 cm² collector pad; defines thermal derating envelope. |
| fT | 40–170 MHz - Transition frequency at VCE = 5 V, IC = 50 mA; indicates usable bandwidth for small-signal amplification or fast switching. |
| VCE(sat) | ≤ 0.6 V - Collector-emitter saturation voltage at IC = 2 A, IB = 200 mA; directly impacts conduction loss in switching applications. |
| Cc | 22 pF - Collector capacitance at VCB = 10 V; influences high-frequency response and switching speed. |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads: two collector terminals (pins 2 and 4) for enhanced thermal and current handling, plus dedicated base (pin 1) and emitter (pin 3). The large collector pad enables efficient heat transfer to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input node; requires ≥200 mA base current to saturate at 2 A collector load. |
| 2 | Collector | Main high-current output terminal; electrically and thermally connected to exposed copper tab. |
| 3 | Emiter | Reference/return path for collector current; tied to system ground in low-side configurations. |
| 4 | Collector | Second collector connection; paralleled with pin 2 to reduce bond wire resistance and improve thermal path. |
Key Features
| Feature | Design Value |
|---|---|
| High power dissipation | 1.35 W on 6 cm² FR4 copper - enables operation without heatsink in space-constrained industrial PCBs. |
| Dual collector terminals | Pins 2 and 4 both connect to collector - lowers effective RDS(on)-like resistance and improves thermal spreading. |
| Two hFE variants | BCP68 (85–375) and BCP68-25 (160–375) - allows precise base drive optimization for specific gain stability requirements. |
| Robust pulsed current | ICM = 3 A (tp ≤ 1 ms) - supports motor startup surges and capacitor charging transients without failure. |
| Wide operating temperature | Tamb = −55 °C to +150 °C - suitable for extended-range industrial and outdoor electronics. |
Applications
| Linear Voltage Regulators | MOSFET Drivers |
|---|---|
|
Use Scenario: Pass transistor in adjustable LDO or series regulator circuits powering microcontrollers and sensors. IC Role / Device Role / Timing Role: NPN pass element controlling output voltage via base bias; handles 1–2 A load current with minimal dropout. Use Value: Low VCE(sat) (≤0.6 V) reduces dropout voltage and thermal load; hFE consistency ensures stable loop gain across temperature. |
Use Scenario: Gate driver stage for discrete N-channel MOSFETs in DC-DC converters and motor controllers. IC Role / Device Role / Timing Role: Medium-current switch sourcing gate charge during turn-on; sinks gate current during turn-off via complementary pair or resistor. Use Value: 2 A IC rating and 3 A ICM support fast gate charging of >10 nF MOSFETs; dual collector pins lower switching losses. |
| Low-Side Switches | Battery-Driven Devices |
|
Use Scenario: Load switch for solenoids, relays, or LED strings in PLC I/O modules and HVAC controls. IC Role / Device Role / Timing Role: Ground-referenced switching element controlled by MCU GPIO; handles inductive kickback with VCEO = 20 V margin. Use Value: V(BR)CEO = 20 V and V(BR)CBO = 32 V provide safety headroom against flyback spikes; rugged SOA supports repetitive switching. |
Use Scenario: Power management in portable test equipment, handheld meters, and wireless sensor nodes. IC Role / Device Role / Timing Role: Battery discharge switch or regulator bypass transistor; operates over full −40 °C to +85 °C ambient range. Use Value: Stable hFE down to −55 °C and low ICBO (<10 µA at 150 °C) ensure reliable cutoff and gain in cold/hot battery environments. |
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 |
|---|---|---|---|
| ZTX653 | Higher VCEO = 60 V, lower IC = 1 A, TO-92 package | Less suited for 2 A continuous loads; better for higher-voltage, lower-current signal switching | Select when voltage margin >30 V is required and thermal mass is not constrained. |
| BCP56-16 | Same SOT223 package, lower hFE = 100–250, identical VCEO/IC ratings | Narrower gain spread reduces base drive variability but limits low-current sensitivity | Choose when tighter hFE tolerance simplifies bias network design in production-critical systems. |
Compared with ZTX653 and BCP56-16, BCP68,115 offers the widest hFE range (85–375) and highest Ptot (1.35 W), making it optimal for thermally demanding, variable-load applications where gain adaptability and PCB-level heat sinking are prioritized.

FAQ
What is the maximum allowable junction temperature for BCP68,115?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of hFE, VCE(sat), and leakage currents. Thermal design must ensure Tj remains below 150 °C under worst-case ambient and power dissipation conditions, using the specified Rth(j-a) values for the chosen PCB layout.
Can BCP68,115 be used in avalanche mode?
No - BCP68,115 is not rated or characterized for avalanche energy absorption. Its V(BR)CEO = 20 V is a DC breakdown specification under controlled test conditions; sustained operation near or beyond this voltage may cause irreversible device failure. Inductive loads require external clamping (e.g., freewheeling diode) to limit VCE to ≤20 V.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 are internally connected to the same collector node and share the exposed copper pad. Both must be soldered to a common, thermally robust copper pour (minimum 6 cm² recommended for 1.35 W). Splitting or isolating these pads degrades thermal performance and increases VCE(sat) due to added bond wire resistance.
Is BCP68,115 automotive-qualified?
No - per Nexperia's revision history (Rev. 9, July 2023), the BCP68 series is explicitly marked as non-automotive qualified. It has not undergone AEC-Q101 stress testing or qualification for automotive temperature ranges, reliability, or failure mechanisms. For automotive use, consult Nexperia's -Q qualified alternatives such as the PBSS4041T.
