Product details
Overview
BC816-25HVL from Nexperia is an NPN general-purpose transistor in SOT23 (TO-236AB) package, rated for 80 V VCEO, 500 mA continuous collector current, and DC current gain (hFE) of 160–400 at VCE = 1 V and IC = 100 mA. It operates reliably up to 175 °C junction temperature and serves as a robust switching or amplification device in 48 V automotive board nets and industrial control interfaces.
For engineers reviewing the BC816-25HVL datasheet, BC816-25HVL pinout, BC816-25HVL application, or BC816-25HVL equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated alternative transistors for high-voltage, medium-current discrete design scenarios.
Technical Context
This transistor features a planar epitaxial silicon structure optimized for stable hFE across temperature (−55 °C to +175 °C) and low VCE(sat) (≤400 mV at IC = 500 mA, IB = 50 mA). Its 80 V VCEO rating supports operation in 48 V systems with margin against load-dump transients.
Thermal resistance Rth(j-a) is 500 K/W on standard FR4 PCB and improves to 363 K/W with 1 cm² collector pad - enabling sustained 500 mA operation under controlled board layout conditions without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Withstands 48 V automotive supply rails plus transient spikes without breakdown. |
| IC (continuous) | 500 mA - Supports medium-power switching loads such as relays, LED drivers, and logic-level interface buffers. |
| hFE | 160–400 @ VCE=1 V, IC=100 mA - Enables predictable base drive sizing for saturation in linear or switch-mode operation. |
| VCE(sat) | ≤400 mV @ IC=500 mA, IB=50 mA - Limits conduction loss to ≤200 mW at full rated current. |
| Tj(max) | 175 °C - Allows deployment in under-hood automotive modules and industrial enclosures without forced air cooling. |
| Cc | 2 pF @ VCB=10 V - Low collector capacitance preserves high-frequency response up to 100 MHz fT. |
| Ptot | 300 mW @ Tamb ≤25 °C (standard footprint) - Defines maximum steady-state power dissipation before thermal derating applies. |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads, 1.3 mm profile, and standard reflow-compatible footprint per Figure 29 in the datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Control input requiring ~50 mA base current to saturate at 500 mA collector load. |
| 2 | Emitter (E) | Common reference node; tied to ground or low-side return path in switching configurations. |
| 3 | Collector (C) | High-side output node; connects to load (e.g., relay coil, LED string) and supply rail. |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage capability | 80 V VCEO enables use in 48 V battery systems with safety margin against ISO 7637-2 pulse 5a (load dump). |
| High-temperature operation | Rated to 175 °C junction temperature - suitable for engine control units and power distribution modules. |
| Two hFE grades | BC816-25H offers 160–400 hFE, providing tighter gain control than BC816-16H (100–250) for consistent biasing. |
| Low saturation voltage | VCE(sat) ≤400 mV ensures <200 mW conduction loss at full 500 mA load, reducing thermal stress on PCB. |
| Standard SOT23 footprint | Compatible with automated placement and reflow processes using IPC-7351B-compliant land patterns. |
Applications
| Automotive 48 V Board Net | Industrial Relay Driver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC817-25 | Same SOT23 package, but VCEO = 45 V and hFE = 160–400 - lower voltage rating limits use in 48 V systems. | Restricted to ≤36 V industrial control; unsuitable for automotive 48 V board net applications. | Select only when operating voltage stays below 40 V and thermal margin is sufficient. |
| MMBT5551 | VCEO = 160 V, hFE = 80–250, but Ptot = 310 mW and Tj(max) = 150 °C - higher voltage, lower gain, and reduced thermal capability. | Better for high-voltage analog amplification; less suitable for high-duty-cycle 500 mA switching at elevated ambient temperatures. | Prefer when >100 V breakdown is required, but avoid where 175 °C operation or tight hFE tolerance is critical. |
Compared with BC816-25HVL, BC817-25 trades voltage headroom for identical gain range in lower-voltage systems, while MMBT5551 provides higher breakdown at the cost of thermal resilience and gain consistency - making BC816-25HVL optimal for 48 V, high-temperature, medium-current switching.

FAQ
Is BC816-25HVL qualified for automotive applications?
No - BC816-25HVL is explicitly marked as non-automotive qualified per Section 13 revision history. It lacks AEC-Q101 qualification and is not tested to automotive reliability standards. For automotive use, Nexperia recommends the Q-qualified BC816Q series variants.
What is the maximum safe continuous collector current at 100 °C ambient?
At Tamb = 100 °C, derating begins at 500 mW total power dissipation. Using Rth(j-a) = 500 K/W (standard footprint), junction temperature rise is 50 K per 100 mW. At 100 °C ambient, max allowable ΔTj-a is 75 K → max Ptot ≈ 150 mW. With VCE(sat) ≈ 300 mV, max IC ≈ 500 mA × (150 mW / 300 mW) = 250 mA.
Does BC816-25HVL have a built-in base-emitter resistor?
No - BC816-25HVL is a bare NPN transistor with no integrated resistors. It requires external base drive circuitry (e.g., current-limiting resistor or active driver) to establish proper bias and prevent thermal runaway during saturation.
How does BC816-25HVL compare to BC816-16H in practical circuit design?
BC816-25HVL offers higher minimum hFE (160 vs. 100), yielding more consistent base current requirements across production lots. This reduces need for gain-bin sorting and simplifies drive-stage design in high-volume manufacturing where predictable saturation is critical.
