Product details
Overview
BAS116 from Nexperia is a low-leakage epitaxial medium-speed switching diode in SOT23 package, designed for precision signal routing and voltage clamping where sub-nA reverse current is critical. It delivers 0.8 µs reverse recovery time, 75 V continuous reverse voltage, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BAS116 datasheet, BAS116 pinout, BAS116 application, or BAS116 equivalent, key selection criteria include leakage sensitivity (3 pA typ.), thermal resistance (500 K/W), junction temperature limit (150 °C), and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
The BAS116 employs an epitaxial silicon structure optimized for low IR and fast trr, enabling stable operation in sample-and-hold circuits and precision analog front-ends. Its 3-pin SOT23 configuration isolates the anode and cathode while leaving pin 2 unconnected to minimize parasitic capacitance.
Thermal performance is defined by Rth(j-a) = 500 K/W on FR4 PCB and Rth(j-sp) = 330 K/W to cathode solder point, supporting continuous operation up to 150 °C junction temperature under derated forward current (215 mA at 25 °C ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse leakage (IR) | 3 pA typical at 75 V, 25 °C - enables nanoamp-level bias stability in sensor interfaces |
| Reverse recovery time (trr) | 0.8 µs typical - supports medium-speed switching in power supply snubbers and signal clamps |
| Repetitive peak reverse voltage (VRRM) | 85 V - allows use in 48 V automotive subsystems with safety margin |
| Forward voltage (VF) | 1.1 V at 50 mA - minimizes conduction loss in low-power logic-level protection |
| Junction temperature (Tj) | 150 °C max - ensures reliability in under-hood automotive modules |
| Diode capacitance (Cd) | 2 pF at 0 V - preserves signal integrity in RF detector and timing applications |
| Power dissipation (Ptot) | 250 mW at 25 °C ambient - defines thermal layout requirements on standard FR4 |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm lead pitch), compliant with IEC 60134 absolute maximum rating system and JEDEC TO-236AB outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward current entry point; connects to positive-side signal or supply rail |
| 2 | Not connected (n.c.) | Electrically isolated terminal; no internal bond wire or die connection |
| 3 | Cathode (K) | Forward current exit and reverse voltage reference; ties to ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics per stress test standard - eliminates need for customer requalification |
| Low leakage current | 3 pA typical at 75 V reverse bias - maintains accuracy in high-impedance feedback networks |
| Medium-speed switching | 0.8 µs trr - balances speed and low-noise performance for EMI-sensitive applications |
| SOT23 footprint | Standardized 3-terminal SMD outline - enables drop-in replacement and automated assembly compatibility |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSVRBAS116WT1G | Same SOT23-3 pinout; 5 pA IR max vs. BAS116's 5 nA IR max; identical VRRM and trr | Optimized for higher-volume automotive production with different tape-and-reel packaging | Select when sourcing from ON Semi distribution channels or requiring alternate logistics traceability |
| Vishay VS-1N4148WS-E3/5BT | Higher IR (25 nA max); faster trr (4 ns); same SOT23-3 but not AEC-Q101 qualified | Preferred in non-automotive consumer timing circuits where speed outweighs leakage | Choose only for cost-sensitive non-automotive designs where 25 nA leakage is acceptable |
Compared with NSVRBAS116WT1G and VS-1N4148WS-E3/5BT, the BAS116 uniquely combines AEC-Q101 qualification, 3 pA typical leakage, and 0.8 µs trr-making it the sole option for automotive sensor conditioning requiring both ultra-low leakage and production-grade reliability.

FAQ
Is BAS116 suitable for reverse polarity protection in 12 V automotive systems?
Yes. With 85 V VRRM and AEC-Q101 qualification, BAS116 supports reverse polarity protection in 12 V systems including start-stop and load-dump conditions. Its 215 mA continuous forward current rating and 1.1 V VF at 50 mA ensure low conduction loss and thermal stability during sustained operation.
What is the significance of pin 2 being unconnected in the SOT23 package?
Pin 2 is electrically isolated with no internal die connection, reducing parasitic capacitance and crosstalk in high-frequency or high-impedance circuits. This design eliminates unintended current paths and improves signal fidelity in precision analog applications such as sensor biasing and sample-and-hold stages.
How does BAS116's thermal resistance affect PCB layout requirements?
Rth(j-a) = 500 K/W on standard FR4 requires minimum copper area around the SOT23 pads to avoid exceeding 150 °C junction temperature. For 215 mA continuous operation, a 25 mm² thermal pad connected via ≥4 thermal vias to inner ground planes is recommended to maintain safe derating margins.
Can BAS116 replace 1N4148 in existing designs?
Only in applications requiring lower leakage and automotive qualification. BAS116 offers 3 pA typical IR versus 25 nA for 1N4148 and is AEC-Q101 qualified, but has slower trr (0.8 µs vs. 4 ns). It is not a direct functional replacement in high-speed digital clamping but excels in precision analog and automotive contexts where leakage dominates performance.
