Product details
Overview
BAS516 from Nexperia is a high-speed switching diode in SOD523 (SC-79) package, rated for 100 V repetitive peak reverse voltage, 4 ns reverse recovery time, and 250 mA forward current at 25 °C ambient. It serves as a fast-turn-off signal path switch in compact DC-DC converter feedback loops, USB port protection circuits, and logic-level clamping networks.
For engineers reviewing the BAS516 datasheet, BAS516 pinout, BAS516 application, or BAS516 equivalent, this page delivers verified electrical parameters, validated SC-79 terminal mapping, real-world switching use cases, and cross-manufacturer alternatives with documented functional trade-offs.
Technical Context
The BAS516 employs a planar epitaxial silicon structure optimized for low charge storage and minimal minority carrier lifetime, enabling sub-4 ns reverse recovery under IF = IR = 10 mA test conditions. Its 1 pF capacitance at 0 V reverse bias and 0.5 µA leakage at 80 V support high-frequency signal routing without parasitic loading.
Thermal resistance from junction to solder point is fixed at 120 K/W, with maximum junction temperature limited to 150 °C. The device operates across –65 °C to +150 °C ambient, maintaining stable VF (≤1.25 V at 150 mA) and IR (≤50 µA at 80 V, 150 °C) over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VRRM) | 100 V - supports input rail protection up to 80 V DC systems with 20 % safety margin |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >100 MHz clocked clamp or sample-hold circuits |
| Forward Voltage (VF) | 855 mV at 10 mA - minimizes conduction loss in low-current logic interface paths |
| Diode Capacitance (Cd) | 1 pF at 0 V - preserves signal integrity in RF detector or high-speed data line clamping |
| Reverse Leakage (IR) | 0.5 µA at 80 V, 25 °C - ensures negligible standby current in battery-powered sensor nodes |
| Thermal Resistance (Rth(j-sp)) | 120 K/W - defines thermal rise per watt dissipated at cathode solder joint on FR4 PCB |
Pinout & Package
Encapsulated in ultra-compact SOD523 (SC-79) plastic SMD package: 1.2 mm × 0.8 mm × 0.6 mm body, flat lead profile optimized for automated placement and reflow soldering on dense PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary current exit node; solder pad connects directly to thermal relief and ground plane for heat extraction |
| 2 | Anode (A) | Current entry node; routed to active circuit node requiring fast turn-on/turn-off control |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal dead-time distortion in synchronous rectifier gate drive paths |
| Low junction capacitance | 1 pF at 0 V reverse bias prevents signal attenuation above 100 MHz in RF sampling circuits |
| Low leakage current | 0.5 µA max at 80 V enables multi-year battery life in always-on IoT wake-up detectors |
| Small footprint | SOD523 outline fits within 1.2 mm × 0.8 mm area-ideal for space-constrained wearables and TWS earbud PCBs |
Applications
| USB 2.0 ESD Protection | DC-DC Converter Feedback Clamp |
|---|---|
|
Use Scenario: Bidirectional transient suppression on D+ and D− lines of USB 2.0 interfaces. IC Role / Device Role / Timing Role: Fast-clamp diode shunting ESD pulses (IEC 61000-4-2 ±8 kV contact) before they reach PHY transceiver inputs. Use Value: 4 ns trr and 1 pF capacitance prevent signal edge degradation during 480 Mbps data transmission. |
Use Scenario: Voltage clamping of optocoupler feedback signals in isolated flyback converters. IC Role / Device Role / Timing Role: High-speed switch limiting feedback voltage swing to protect error amplifier input. Use Value: 100 V VRRM withstands reflected primary-side transients; 0.5 µA IR avoids bias current error in precision regulation. |
| Logic-Level Signal Clamping | RF Detector Diode |
|
Use Scenario: Input protection for 3.3 V microcontroller GPIO pins exposed to external sensors. IC Role / Device Role / Timing Role: Low-capacitance clamp limiting voltage excursions to safe levels during hot-plug events. Use Value: 1 pF Cd avoids RC delay; 855 mV VF at 10 mA ensures accurate logic threshold referencing. |
Use Scenario: Envelope detection in 2.4 GHz ISM-band receiver front-ends. IC Role / Device Role / Timing Role: Zero-bias RF demodulator converting RF amplitude to baseband voltage. Use Value: 1 pF Cd and 4 ns trr preserve detector response up to 2.5 GHz; low IR maintains DC offset stability. |
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 NSVRBAS516MWXT5G | Same SOD523 package, identical trr (4 ns), but VF = 950 mV @ 10 mA (100 mV higher) | Higher forward drop increases power loss in high-duty-cycle clamp circuits | Select when supply chain diversification is required and 100 mV VF increase is acceptable |
| Diodes Incorporated BAV99W-7-F | Dual-series SOT-323 package, trr = 4 ns, VR = 70 V (30 V lower), Cd = 2 pF (2× higher) | Limited to ≤70 V systems; higher capacitance degrades >50 MHz signal fidelity | Choose only for dual-diode configurations where board space allows SOT-323 and voltage headroom ≥30 V exists |
Compared with NSVRBAS516MWXT5G and BAV99W-7-F, the BAS516 offers the lowest VF among SOD523-switching diodes and the only 100 V rating in this footprint-critical for industrial 48 V bus clamping and automotive infotainment power domains.

FAQ
What is the maximum continuous forward current rating for BAS516 at 70 °C ambient?
The datasheet specifies 250 mA maximum forward current at Tamb = 25 °C with derating to 150 mA at Tamb = 70 °C, based on thermal resistance of 120 K/W and maximum junction temperature of 150 °C. This assumes mounting on FR4 PCB with single-sided copper and standard SOD523 footprint.
Can BAS516 be used in place of BAS16 in existing designs?
Yes-BAS516 is a direct replacement for BAS16 with identical SOD523 package, pinout, and key parameters (trr ≤ 4 ns, VRRM = 100 V, VF ≤ 855 mV). It improves upon BAS16 with lower leakage (0.5 µA vs. 1 µA) and tighter Cd tolerance (1 pF vs. 1.5 pF), making it suitable for higher-precision applications.
Does BAS516 meet RoHS and REACH compliance requirements?
Yes-BAS516 is manufactured by Nexperia in accordance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Full compliance documentation, including substance declarations and test reports, is available via Nexperia's official product portal using part number BAS516.
What is the recommended reflow profile for BAS516's SOD523 package?
Nexperia recommends a lead-free reflow profile with peak temperature of 260 °C for ≤10 seconds, ramp-up rate ≤3 °C/s, and time above 217 °C of 60–150 seconds. The footprint must follow Figure 8 in the datasheet: 0.85 mm × 0.75 mm solder lands with 0.5 mm spacing and 0.4 mm solder resist opening.
