Product details
Overview
BAS316/DG/B3,115 from Nexperia is a high-speed switching diode in SOD323 (SC-76) package, configured as a single discrete silicon diode with cathode-anode polarity. It delivers trr ≤ 4 ns reverse recovery time, VR = 100 V maximum reverse voltage, and IF = 250 mA forward current rating at Tamb ≤ 25 °C - enabling use in compact DC-DC converter flyback snubbers and high-frequency signal routing circuits.
For engineers reviewing the BAS316/DG/B3,115 datasheet, BAS316/DG/B3,115 pinout, BAS316/DG/B3,115 application, or BAS316/DG/B3,115 equivalent, key selection criteria include verified 4 ns trr performance under IF = 10 mA / IR = 10 mA test conditions, low 1.5 pF capacitance at 1 MHz / 0 V, and AEC-Q101 qualification for automotive-grade reliability in space-constrained PCB layouts.
Technical Context
This diode employs planar epitaxial construction optimized for fast minority-carrier recombination, achieving sub-4 ns reverse recovery without soft-recovery tail. Its junction design minimizes stored charge (Qrr), supporting clean turn-off in PWM-controlled power stages up to 100 MHz.
The SOD323 package features a 2-terminal configuration with cathode marked by a bar on the top surface, enabling unambiguous orientation during automated placement. Thermal resistance Rth(j-sp) is 55 K/W to solder point, allowing sustained 250 mA operation with minimal thermal derating on standard FR4 boards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | 4 ns max - enables clean switching in >10 MHz DC-DC controllers without voltage overshoot |
| Repetitive Peak Reverse Voltage (VRRM) | 100 V - supports input-stage clamping in 48 V automotive systems and industrial 24–48 V rails |
| Forward Current (IF) | 250 mA - sufficient for signal-level switching and low-power snubber duty in SMT designs |
| Diode Capacitance (Cd) | 1.5 pF at 1 MHz / 0 V - preserves signal integrity in RF detector and high-speed logic interface paths |
| Reverse Leakage (IR) | 0.5 µA at VR = 80 V - ensures minimal standby power loss in battery-backed monitoring circuits |
| Forward Voltage (VF) | 855 mV typ at IF = 10 mA - balances conduction loss and thermal rise in compact footprint applications |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood automotive environments without forced cooling |
Pinout & Package
The BAS316/DG/B3,115 is housed in a SOD323 (SC-76) plastic surface-mounted package measuring 1.7 mm × 1.3 mm × 0.9 mm, with two terminals and cathode polarity indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to circuit ground or negative rail; marked by bar on package top; carries reverse-biased voltage stress |
| 2 | Anode | Connected to switched node or positive rail; source of forward current path during conduction phase |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade temperature cycling (−65 °C to +150 °C), vibration, and humidity exposure |
| Ultra-small SOD323 footprint | 1.7 × 1.3 mm body size - saves >60% board area vs. SOT23 while maintaining 250 mA current capability |
| Low Qrr charge | Enables zero-voltage switching (ZVS) assist in resonant converters without external gate drive compensation |
| Low thermal resistance Rth(j-sp) | 55 K/W to solder point - permits full 250 mA rating without heatsinking on standard 1-oz copper FR4 |
| High VR/VRRM rating | 100 V blocking - eliminates need for series stacking in 48 V bus protection and ESD clamp networks |
Applications

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 |
|---|---|---|---|
| BAS516,115 | Smaller SOD523 package (1.25 × 0.85 mm); identical trr (4 ns), but lower IF = 150 mA and Cd = 1.0 pF | Better suited for ultra-dense RF front-end bias networks where capacitance dominates layout constraints | Select when board space is <1.0 mm² per diode and peak current stays below 150 mA |
| BAS16,215 | SOT23-3 package with NC pin; same electrical specs but larger footprint (2.9 × 1.3 mm) and higher Rth(j-a) = 500 K/W | Preferred for manual prototyping or legacy designs requiring through-hole-compatible pick-and-place tooling | Choose when thermal margin is available and compatibility with existing SOT23 footprints is required |
Compared with BAS316/DG/B3,115, BAS516 offers tighter capacitance control at the expense of current handling, while BAS16 trades miniaturization for mechanical robustness and broader assembly compatibility - making BAS316 the optimal balance of speed, size, and power in new automotive and industrial SMT designs.

FAQ
What is the cathode marking convention for BAS316/DG/B3,115?
The cathode is identified by a visible bar marking on the top surface of the SOD323 package. Pin 1 is the cathode terminal, and Pin 2 is the anode - consistent with Table 3 and Figure 15 in the Nexperia BAS16_SER Rev. 6 datasheet. This orientation is confirmed by the device's schematic symbol and physical package outline.
Does BAS316/DG/B3,115 support reflow soldering per JEDEC J-STD-020?
Yes - the SOD323 package is qualified for standard lead-free reflow profiles (peak 260 °C, 10 s max). Figure 28 in the datasheet provides the recommended reflow footprint (0.5 mm × 0.6 mm solder pads, 0.95 mm pitch), and thermal resistance data confirms reliable operation post-reflow with Rth(j-sp) = 55 K/W.
Can BAS316/DG/B3,115 replace 1N4148 in high-frequency applications?
Yes - with trr ≤ 4 ns (vs. 1N4148's 4–8 ns), VF = 855 mV at 10 mA (vs. ~900 mV), and 1.5 pF capacitance (vs. ~2 pF), BAS316 delivers measurably faster switching and lower parasitics. Its AEC-Q101 qualification further extends reliability beyond commercial-grade 1N4148 in automotive and industrial use cases.
Is there a halogen-free version of BAS316/DG/B3,115?
Yes - Nexperia specifies all BAS16-series devices, including BAS316/DG/B3,115, as halogen-free per IEC 61249-2-21. The material composition complies with Nexperia's "Green" product definition (no brominated flame retardants, no chlorine above 900 ppm), documented in their environmental compliance statements.
