Product details
Overview
BC816-16HVL 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 100–250 at VCE = 1 V and IC = 100 mA. It operates 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 BC816-16HVL datasheet, BC16-16HVL pinout, BC816-16HVL application, or BC816-16HVL equivalent, this page delivers verified electrical parameters, thermal derating behavior, SOT23 terminal mapping, and validated alternatives for high-reliability discrete selection in temperature-stressed environments.
Technical Context
This transistor employs a planar epitaxial silicon structure optimized for stable hFE across wide temperature ranges (−55 °C to +175 °C), with low VCE(sat) ≤ 400 mV at IC = 500 mA and IB = 50 mA. Its 80 V VCEO rating supports operation in 48 V nominal systems with margin for transients.
Thermal performance is defined by two mounting conditions: Rth(j-a) = 500 K/W on standard FR4 footprint and 363 K/W with 1 cm² collector pad-enabling precise power dissipation planning in space-constrained PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 80 V - Withstands 48 V system transients without breakdown |
| IC (continuous) | 500 mA - Supports medium-power switching loads like relays and LED drivers |
| hFE | 100–250 - Ensures reliable base drive margin for saturation in digital logic interfacing |
| VCE(sat) | ≤ 400 mV @ IC=500 mA, IB=50 mA - Minimizes conduction loss and self-heating |
| Tj(max) | 175 °C - Enables use in under-hood automotive or industrial enclosures without forced cooling |
| Ptot | 300 mW (standard footprint) - Defines maximum steady-state power before thermal throttling |
| fT | 100 MHz - Supports high-speed switching up to ~10 MHz square-wave operation |
Pinout & Package
SOT23 (TO-236AB) plastic surface-mount package with 3 leads; 1.9 mm × 1.1 mm body, 0.45 mm profile, and tin-plated terminations compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Base (B) | Controls conduction state; requires ≥10 mA drive for full saturation at 500 mA load |
| 2 | Emitter (E) | Reference node for biasing; connected to ground or low-side return path |
| 3 | Collector (C) | High-side load connection; thermally coupled to PCB pad for enhanced power handling |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature operation | Junction-rated to 175 °C-eliminates need for derating in sealed enclosures |
| Two hFE grades | BC816-16H (100–250) and BC816-25H (160–400) enable precise gain matching per circuit requirement |
| Low VCE(sat) | ≤ 400 mV ensures <100 mW conduction loss at full rated current, reducing thermal stress |
| Robust transient capability | 1 A peak collector current (tp ≤ 1 ms) supports inrush current handling in relay coils and solenoids |
| Standard SOT23 footprint | Enables drop-in replacement and automated assembly without layout redesign |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC817-16,215 | Same SOT23 package, identical hFE range (100–250), but lower VCEO = 45 V | Not suitable for 48 V net applications requiring >60 V transient margin | Select only for ≤36 V systems where cost optimization outweighs voltage headroom needs |
| MMBT3904LT1G | Higher fT (300 MHz), same VCEO = 40 V, hFE = 100–300, but Tj(max) = 150 °C | Limited to lower-temperature industrial environments; insufficient for under-hood use | Prefer when high-frequency switching (>5 MHz) dominates over thermal robustness |
Compared with BC816-16HVL, BC817-16 sacrifices voltage margin for legacy compatibility, while MMBT3904LT1G trades thermal resilience for RF performance-making BC816-16HVL uniquely balanced for 48 V automotive and high-temp industrial switching.

FAQ
What is the maximum allowable base current for BC816-16HVL?
The absolute maximum pulsed base current is 200 mA (tp ≤ 1 ms, Tamb = 25 °C). For continuous operation, design must limit IB to ensure junction temperature stays within 175 °C-typically ≤20 mA with adequate PCB copper area. Exceeding 200 mA pulse risks metallization failure even if average power appears safe.
Does BC816-16HVL meet AEC-Q101 requirements?
No-BC816-16HVL is explicitly marked as non-automotive qualified per Nexperia's revision history (Rev. 2, Sept. 2025). It lacks AEC-Q101 stress testing and qualification documentation. For automotive applications, Nexperia recommends the BC816-Q series variants, which undergo full AEC-Q101 qualification including HTGB, AC-H3TRB, and temperature cycling.
Can BC816-16HVL be used in linear amplification mode?
Yes-it is characterized for linear operation with specified hFE, VBE, and fT across temperature and bias conditions. However, its primary design focus is switching; for precision analog amplification, dedicated low-noise transistors (e.g., BC549C) offer better hFE consistency and lower noise density below 1 kHz.
How does thermal resistance change with PCB copper area?
Rth(j-a) drops from 500 K/W (standard SOT23 footprint) to 363 K/W when the collector pad is expanded to 1 cm² on single-sided FR4. This 27 % improvement enables ~35 % higher continuous power dissipation before reaching Tj = 175 °C, confirmed by Nexperia's Fig. 1 derating curves.
