Product details
Overview
BCP55-16,115 from Nexperia is a medium-power NPN bipolar junction transistor in SOT223 (SC-73) package, rated for 60 V VCEO, 1 A continuous collector current, and DC current gain (hFE) of 100–250 at VCE = 2 V and IC = 150 mA. It delivers 1.35 W total power dissipation with 6 cm² copper pad, and serves as a low-side switch or MOSFET driver in battery-powered linear regulators and power management circuits.
For engineers reviewing the BCP55-16,115 datasheet, BCP55-16,115 pinout, BCP55-16,115 application, or BCP55-16,115 equivalent, key selection criteria include verified hFE binning (100–250), thermal resistance to solder point (16 K/W), peak pulse current capability (2 A), and SOT223 footprint compatibility with high-current PCB heatsinking.
Technical Context
This transistor operates as a saturated-switch or linear amplifier with guaranteed hFE ≥100 at IC = 150 mA and VCE = 2 V, supporting stable biasing in feedback-controlled voltage regulators. Its 60 V VCEO and 5 V VEBO enable use in 24 V industrial rails and battery systems up to 48 V nominal.
Thermal design relies on its low Rth(j-sp) of 16 K/W and scalable Rth(j-a) (93–192 K/W depending on copper area), allowing predictable derating from 1.35 W down to 0.65 W on standard FR4. The dual-collector pin (pins 2 and 4) provides enhanced current handling and thermal path redundancy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Supports operation in 24 V/48 V systems with margin against transients and ripple. |
| IC (continuous) | 1 A - Enables direct drive of loads such as relays, LEDs, or gate resistors in MOSFET drivers. |
| hFE | 100–250 @ VCE=2 V, IC=150 mA - Ensures reliable base drive sizing for saturation in switching applications. |
| Ptot | 1.35 W @ 6 cm² collector pad - Delivers >2× power handling vs. standard SOT223 footprints without forced cooling. |
| Rth(j-sp) | 16 K/W - Enables rapid heat transfer to PCB copper, critical for sustained 1 A conduction in compact layouts. |
| VCE(sat) | ≤0.5 V @ IC=500 mA, IB=50 mA - Limits switching losses and self-heating during active conduction. |
| fT | 100–180 MHz - Supports moderate-speed switching (e.g., <500 kHz PWM) and small-signal amplification. |
Pinout & Package
The BCP55-16,115 is housed in a SOT223 (SC-73) surface-mount plastic package with four leads and an integrated heatsink tab (pin 2 and pin 4 both connected to collector). The package measures 6.7 × 3.7 × 1.8 mm and requires a 6 cm² copper pour on the collector pad for full 1.35 W rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; accepts ~50 mA base current for full 1 A collector saturation. |
| 2 | Collector | Main power output terminal; electrically and thermally tied to exposed metal tab for heatsinking. |
| 3 | Emitter | Reference node for bias network; connects directly to ground or low-side return path. |
| 4 | Collector | Second collector connection; paralleled with pin 2 to reduce bond wire inductance and improve thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE bins | BCP55-16 offers 100–250 hFE, enabling precise base resistor selection without overdesign or marginal turn-on. |
| Dual-collector SOT223 | Pins 2 and 4 both connect to collector, reducing effective thermal resistance and improving current sharing under pulse loads. |
| High Ptot scalability | Power rating scales from 0.65 W (standard footprint) to 1.35 W (6 cm² pad), supporting flexible thermal design across cost/performance tiers. |
| Low VCE(sat) | ≤0.5 V at IC/IB = 10 ensures minimal conduction loss and stable thermal behavior in linear regulator pass elements. |
| Robust breakdown ratings | 60 V VCEO and VCBO, plus 5 V VEBO, support operation in noisy 24 V industrial environments with ESD coupling. |
Applications
| Linear Voltage Regulators | Power Management |
|---|---|
|
Use Scenario: Pass transistor in adjustable 3-terminal linear regulators delivering up to 1 A at 5–24 V output. IC Role / Device Role / Timing Role: Primary current-handling element regulating output by varying VBE-controlled conduction. Use Value: Low VCE(sat) minimizes dropout voltage; high hFE reduces base drive burden on error amplifier. |
Use Scenario: Load switch or OR-ing diode replacement in multi-rail power domains (e.g., USB-C PD adapters). IC Role / Device Role / Timing Role: Controlled low-side switch enabling/disabling downstream 12 V or 24 V subsystems. Use Value: 1 A continuous rating and 2 A pulse capability support inrush-limited hot-swap sequencing without external current limiting. |
| Low-Side Switches | MOSFET Drivers |
|

IC Role / Device Role / Timing Role: Saturated switch turning on/off load between ground and supply rail. Use Value: Dual-collector construction improves reliability under repetitive 1 A switching with minimal thermal cycling stress. |
Use Scenario: Gate driver stage for N-channel power MOSFETs in DC-DC converters or motor H-bridges. IC Role / Device Role / Timing Role: Current-amplifying buffer between logic-level controller and MOSFET gate capacitance. Use Value: 180 MHz fT enables fast gate charging; high hFE allows microcontroller GPIO direct drive without external base resistors. |
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 |
|---|---|---|---|
| BCP55-10,115 | hFE = 63–160 (lower mid-range gain bin); identical VCEO, IC, package, and thermal specs. | Suitable where lower gain tolerance is acceptable and base drive current can be increased slightly. | Select when designing for worst-case hFE margin above 63 and board space is constrained to SOT223. |
| BCP52-16,115 | PNP complement; same VCEO, IC, hFE range, and SOT223 package but opposite polarity. | Required for high-side switching, complementary push-pull stages, or inverted logic interfaces. | Choose only when circuit topology demands PNP configuration-no functional substitution in NPN positions. |
Compared with BCP55-10,115, the BCP55-16,115 provides higher minimum hFE (100 vs. 63), reducing base current sensitivity and improving stability in precision current mirrors or low-noise preamps; versus BCP52-16,115, it is not interchangeable due to polarity reversal, requiring full schematic revalidation.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134. For reliable long-term operation, maintain Tj ≤125 °C using derated power based on ambient temperature and PCB copper area. At 25 °C ambient with 6 cm² collector pad, full 1.35 W is permitted; above 75 °C ambient, power must be reduced per Fig. 1 in the datasheet.
Can BCP55-16,115 be used in avalanche mode?
No. The BCP55-16,115 is not rated or characterized for avalanche energy handling. Its absolute maximum ratings specify only VCEO = 60 V under open-base conditions; operation beyond this voltage risks irreversible breakdown. Use TVS clamping or snubbers for inductive load protection.
Is the SOT223 footprint compatible with automated optical inspection (AOI)?
Yes. The SOT223 package has defined solder land dimensions (Fig. 10), clear fiducials, and symmetric lead geometry that supports standard AOI algorithms. The exposed collector pad provides strong contrast for thermal pad inspection, and the 0.6–0.8 mm lead pitch meets typical AOI resolution requirements for Class II/III assembly.
How does the dual-collector configuration affect PCB layout?
Pins 2 and 4 are internally shorted to the collector and the exposed metal tab. Layout must connect both pins-and the tab-to the same large copper pour. Splitting or isolating either pin degrades thermal performance and may cause current imbalance, localized heating, or premature failure under sustained 1 A load.
