Product details
Overview
BCP55-16F from Nexperia is an NPN medium power bipolar junction transistor in SOT223 (SC-73) package, rated for 60 V VCEO, 1 A continuous collector current, and 2 A peak pulse current. It delivers DC current gain (hFE) of 100–250 at VCE = 2 V and IC = 150 mA, with low VCE(sat) ≤ 0.5 V at IC = 500 mA / IB = 50 mA - optimized for low-side switching in battery-powered linear regulators and MOSFET gate drive circuits.
For engineers reviewing the BCP55-16F datasheet, BCP55-16F pinout, BCP55-16F application, or BCP55-16F equivalent, key selection criteria include its 100–250 hFE binning, 1.35 W power dissipation on 6 cm² copper pad, thermal resistance Rth(j-sp) = 16 K/W, and SOT223 pin-compatible layout for thermal reliability in compact power management designs.
Technical Context
This transistor operates as a medium-power NPN switch or linear amplifier with fixed-emitter bias topology. Its 60 V VCEO and 5 V VEBO support operation across 12–48 V rail systems, while pulsed ICM = 2 A enables robust transient handling in driver stages.
Thermal design relies on the SOT223's exposed collector tab: Rth(j-a) drops from 192 K/W (standard footprint) to 93 K/W (6 cm² pad), and Rth(j-sp) = 16 K/W confirms direct thermal path to PCB solder point - critical for sustained 1 A conduction without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - supports 48 V industrial bus and automotive 24 V systems with margin |
| IC (continuous) | 1 A - sufficient for driving logic-level MOSFET gates or regulating 500 mA loads |
| hFE | 100–250 @ VCE=2 V, IC=150 mA - ensures stable base drive with low IB variation across temperature |
| VCE(sat) | ≤ 0.5 V @ IC=500 mA, IB=50 mA - minimizes conduction loss in low-side switch applications |
| Ptot | 1.35 W @ 6 cm² copper pad - enables high-current operation without heatsink in space-constrained PCBs |
| fT | 100–180 MHz - supports fast switching in PWM drivers up to ~10 MHz practical frequency |
| Rth(j-sp) | 16 K/W - confirms efficient heat transfer from die to solder joint for thermal stability |
Pinout & Package
SOT223 (SC-73) surface-mount plastic package with 4 leads: pins 1 (base), 2 (collector), 3 (emitter), and 4 (collector). The dual-collector configuration enhances thermal dissipation and current handling via the exposed metal tab connected to pins 2 and 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base | Control input; requires current-limited drive (max IB = 0.3 A) to avoid saturation delay |
| 2 | Collector | Main current path input; electrically tied to pin 4 and thermal pad for power dissipation |
| 3 | Emitter | Reference node for biasing; connects to ground or low-side return path in switch configurations |
| 4 | Collector | Redundant collector terminal; shares internal connection with pin 2 to improve thermal and current capacity |
Key Features
| Feature | Design Value |
|---|---|
| Three hFE bins | BCP55-16 offers 100–250 hFE, enabling precise base resistor selection for consistent switching thresholds |
| High Ptot capability | 1.35 W with 6 cm² copper pad - eliminates need for external heatsink in 1 A load switching |
| Dual-collector SOT223 | Pins 2 + 4 and thermal tab provide parallel current paths and low Rth(j-sp) = 16 K/W |
| Robust voltage ratings | 60 V VCEO/VCBO and 5 V VEBO support 24/48 V systems with ESD-safe bias margins |
Applications
| Linear Voltage Regulators | Power Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN medium power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP54-16 | Lower VCEO = 45 V; identical hFE bin (100–250) and SOT223 package | Not suitable for 48 V bus systems; limited to ≤36 V applications | Select when operating voltage stays below 40 V and cost optimization is prioritized |
| ZTX653 | Higher VCEO = 100 V; hFE = 100–300; TO-92 package (no thermal pad) | Lacks SOT223 thermal performance; unsuitable for >500 mA continuous conduction | Choose only for low-current, high-voltage bias networks where PCB space permits through-hole mounting |
Compared with BCP54-16 and ZTX653, BCP55-16F uniquely balances 60 V rating, 1 A continuous current, and SOT223 thermal efficiency - making it the optimal choice for compact, high-reliability 24–48 V low-side switches requiring minimal board area and no external heatsinking.

FAQ
What is the maximum safe operating temperature for BCP55-16F?
The absolute maximum junction temperature is 150 °C, and storage temperature ranges from –65 °C to 150 °C. Operation at full 1 A current requires a minimum 6 cm² copper pad to maintain Tj ≤ 150 °C at 70 °C ambient - verified by Rth(j-a) = 93 K/W under those conditions.
Does BCP55-16F support pulse-width modulation (PWM) switching?
Yes - with fT = 100–180 MHz and ICM = 2 A (tp ≤ 1 ms), BCP55-16F supports PWM frequencies up to 10 MHz in gate-driving roles. Its VCE(sat) ≤ 0.5 V and low Cc = 6 pF minimize switching losses and propagation delay in totem-pole configurations.
How does the dual-collector SOT223 configuration improve performance?
Pins 2 and 4 are internally shorted to the same collector node and connected to the exposed thermal pad. This doubles current-carrying capacity per lead and reduces thermal resistance to the PCB - achieving Rth(j-sp) = 16 K/W and enabling 1.35 W dissipation without a heatsink.
Is BCP55-16F qualified for automotive applications?
No - this part is non-automotive qualified per Nexperia's revision history (v.9, July 2022). It lacks AEC-Q101 stress testing and automotive-specific screening. For automotive use, Nexperia recommends the BCP55-16Q variant, which carries full AEC-Q101 qualification and extended temperature validation.
