Product details
Overview
BAS316 from Nexperia is a high-speed switching diode in SOD323 (SC-76) surface-mount package, designed for fast signal routing and low-loss rectification in compact DC-DC converters and digital logic interfaces. Confirmed parameters include reverse voltage ≤100 V, reverse recovery time ≤4 ns, forward voltage ≤1.25 V at 150 mA, reverse leakage ≤0.5 µA at 80 V, and junction temperature up to 150 °C.
For engineers reviewing the BAS316 datasheet, BAS316 pinout, BAS316 application, or BAS316 equivalent, this page delivers verified electrical behavior, thermal limits, package dimensions, cathode/anode terminal mapping, and real-world switching performance under defined test conditions - all critical for high-frequency power management and signal integrity validation.
Technical Context
The BAS316 operates as a planar epitaxial silicon switching diode with optimized carrier lifetime control to achieve trr ≤4 ns under IF = IR = 10 mA, RL = 100 Ω, and IR(meas) = 1 mA. Its low 1.5 pF capacitance at 0 V and 1 MHz enables minimal signal distortion in RF-coupled paths and clock line clamping.
Thermal resistance from junction to solder point is 150 K/W in free air, with maximum total power dissipation of 400 mW at Tsp ≤90 °C. It supports repetitive peak forward current up to 500 mA and non-repetitive surge current up to 4 A for tp = 1 µs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse voltage (VR) | 100 V - defines maximum continuous blocking capability without breakdown in DC bias applications. |
| Reverse recovery time (trr) | 4 ns - enables operation above 50 MHz in flyback snubbers and high-speed data line protection. |
| Forward voltage (VF) | 1.25 V at 150 mA - ensures low conduction loss in low-voltage logic-level clamping circuits. |
| Reverse leakage (IR) | 0.5 µA at 80 V, 25 °C - guarantees minimal standby current in battery-powered signal conditioning stages. |
| Diode capacitance (Cd) | 1.5 pF at 0 V, 1 MHz - preserves signal edge integrity in <100 MHz digital timing paths. |
| Junction temperature (Tj) | 150 °C - allows reliable operation in thermally constrained PCB layouts near power ICs. |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 2-pin, 1.3 mm pitch, 1.7 mm × 1.25 mm × 0.95 mm body size, cathode tab solder point for thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary current exit node; connects to ground or lower-potential rail; solder point serves as thermal interface. |
| 2 | Anode (A) | Current entry node; ties to input source or higher-potential rail; no internal thermal pad connection. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤4 ns enables clean transitions in >25 MHz clock distribution networks and pulse shaping circuits. |
| Low junction-to-solder-point thermal resistance | Rth(j-sp) = 150 K/W supports sustained 250 mA forward current without derating on standard FR4 PCBs. |
| Low reverse leakage | IR ≤0.5 µA at 80 V ensures stable reference voltage hold in sample-and-hold and precision comparator inputs. |
| Small footprint compatibility | SOD323 outline fits 1.7 mm × 1.25 mm board area - ideal for space-constrained USB-C PD controllers and PMIC sequencers. |
Applications
| USB Power Delivery Clamping | Digital Logic Level Translation |
|---|---|
Use Scenario: Protecting CC and VCONN lines against ESD and overvoltage transients in USB-C receptacles. IC Role / Device Role: Fast-switching clamp diode shunting transient energy to ground before it reaches controller I/O pins. Use Value: 4 ns trr and 1.5 pF capacitance prevent signal degradation on 3 A/5 A negotiation lines operating at 300 kHz baseband. |
Use Scenario: Bidirectional level shifting between 3.3 V microcontroller GPIOs and 5 V peripheral buses. IC Role / Device Role: Passive diode-based level translator enabling open-drain communication without active circuitry. Use Value: Low VF (≤855 mV at 10 mA) minimizes voltage drop across translation path while maintaining TTL-compatible thresholds. |
| DC-DC Converter Snubber | RF Signal Path Isolation |
Use Scenario: Suppressing voltage spikes across synchronous rectifier MOSFETs in 500 kHz buck converters. IC Role / Device Role: Fast-recovery snubber diode absorbing inductive kickback during MOSFET turn-off. Use Value: 100 V VR rating and 4 ns trr ensure reliable clamping of 60–80 V transients without oscillation or secondary breakdown. |
Use Scenario: DC blocking and RF coupling in 2.4 GHz ISM band front-end modules. IC Role / Device Role: Low-capacitance series diode isolating DC bias while passing RF signals with minimal insertion loss. Use Value: 1.5 pF Cd and <0.5 µA IR maintain >30 dB isolation at 2.4 GHz while preserving impedance matching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR0230P2T5G | Lower VF (0.35 V typ. at 100 mA), but higher trr (5 ns) and smaller VR (30 V). | Limited to ≤30 V systems; better for ultra-low-loss 3.3 V logic clamping, not suitable for 100 V snubbers. | Select when forward voltage drop dominates design priority and reverse voltage stays below 30 V. |
| Vishay 1N4148WS | Same SOD323 package, but trr = 4 ns (typ.), VR = 100 V, and IR = 25 nA (lower leakage). | Superior leakage performance suits precision analog sampling; identical switching speed and voltage rating. | Prefer for low-leakage analog front-ends where sub-100 nA IR is required at elevated temperatures. |
Compared with NSR0230P2T5G and 1N4148WS, the BAS316 delivers balanced trade-offs: full 100 V blocking with 4 ns trr and 0.5 µA IR - making it optimal for mixed-signal power management where both voltage margin and speed matter.

FAQ
What is the maximum allowable forward current for continuous operation?
The BAS316 supports 250 mA continuous forward current at Tj = 25 °C when mounted on an FR4 PCB with single-side copper and standard footprint. Derating is required above 25 °C ambient; at 85 °C, maximum IF drops to approximately 150 mA based on thermal resistance and power dissipation limits.
Can BAS316 be used in automotive applications?
No - the BAS316 is explicitly marked as non-automotive qualified in its revision history. It lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing. For automotive use, Nexperia offers the BAS316-Q variant, which meets AEC-Q101 requirements and supports extended temperature operation.
How does the SOD323 package affect thermal performance?
The SOD323 package provides a direct thermal path from the die to the cathode solder point, achieving Rth(j-sp) = 150 K/W in free air. This allows effective heat transfer to the PCB copper pour, enabling 400 mW total power dissipation when the solder point is thermally anchored to ≥1 cm² of 1 oz copper.
Is the marking code 'A6' unique to BAS316?
Yes - per Nexperia's marking table, 'A6' is the official top-side laser marking for the BAS316 in SOD323 packaging. The alternate version BAS316/DG uses 'KN', confirming that 'A6' unambiguously identifies the standard commercial-grade device without additional suffixes.
