Product details
Overview
BAS516,135 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 BAS516,135 datasheet, BAS516,135 pinout, BAS516,135 application, or BAS516,135 equivalent, key selection criteria include trr ≤ 4 ns, VR ≤ 100 V, IF = 250 mA (Tamb = 25 °C), Cd = 1 pF at 0 V, and thermal resistance Rth(j-sp) = 120 K/W - all critical for high-frequency signal integrity and thermal-limited board space.
Technical Context
The BAS516,135 employs a planar epitaxial silicon structure optimized for low charge storage and minimal minority-carrier lifetime, enabling sub-4 ns reverse recovery under IF = 10 mA / IR = 10 mA test conditions with RL = 100 Ω. Its junction capacitance remains stable at ≤1 pF up to 0 V reverse bias, supporting RF bypass and high-speed sampling applications.
Designed for surface-mount operation on FR4 PCBs with single-sided copper, the device uses cathode-tab solder-point thermal coupling (Rth(j-sp) = 120 K/W) and supports pulsed forward currents up to 4 A (tp = 1 µs) while maintaining Tj ≤ 150 °C - essential for transient surge handling in power rail conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 100 V max - defines maximum blocking capability in DC-DC flyback snubbers or input polarity protection. |
| trr (Reverse Recovery Time) | 4 ns max - enables clean switching at >100 MHz clock edges without tail current-induced crosstalk. |
| IF (Forward Current) | 250 mA continuous at Tamb = 25 °C - supports logic-level signal routing and low-power load switching. |
| Cd (Capacitance) | 1 pF at VR = 0 V, f = 1 MHz - minimizes signal distortion in RF detector and antenna tuning paths. |
| IR (Reverse Leakage) | 0.5 µA at VR = 80 V, Tamb = 25 °C - ensures low standby power loss in battery-backed sensing nodes. |
| Rth(j-sp) | 120 K/W - allows direct thermal path to PCB copper, critical for thermal management in dense SMT layouts. |
Pinout & Package
Encapsulated in the ultra-small SOD523 (SC-79) plastic SMD package (1.2 mm × 0.8 mm × 0.6 mm body), the BAS516,135 features a two-terminal configuration with defined anode and cathode terminals for unidirectional conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to PCB cathode pad; serves as primary thermal interface (solder point) and negative reference for forward conduction. |
| 2 | Anode (A) | Input terminal for forward-biased current flow; requires trace routing compatible with 250 mA steady-state current density. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns enables use in >100 MHz digital signal clamping without propagation delay skew. |
| Low leakage current | IR ≤ 0.5 µA at 80 V supports microampere-level sleep-mode current budgets in portable devices. |
| Ultra-small footprint | SOD523 package (1.2 × 0.8 mm) fits within 1.5 mm² board area - ideal for space-constrained IoT sensor modules. |
| Thermal performance | Rth(j-sp) = 120 K/W permits direct junction-to-PCB heat transfer, reducing need for thermal vias in cost-sensitive designs. |
Applications
| USB Port ESD Protection | DC-DC Converter Feedback Path |
|---|---|
Use Scenario: Clamps transient overvoltage on USB D+ and D− lines during hot-plug events or ESD strikes. IC Role / Device Role / Timing Role: Fast-switching clamp diode placed between data line and ground, activated within nanoseconds of overvoltage onset. Use Value: 4 ns trr and 1 pF capacitance prevent signal edge degradation while limiting clamping voltage to <12 V at 8 kV HBM. | Use Scenario: Provides precise voltage reference path from output to feedback pin in isolated flyback converters. IC Role / Device Role / Timing Role: High-speed rectifier in optocoupler-based feedback loop, isolating secondary-side error signal. Use Value: Low IR (0.5 µA) avoids feedback current error; 100 V VR rating accommodates reflected output transients up to 80 V. |
| Logic-Level Signal Clamping | RF Detector Input Stage |
Use Scenario: Limits TTL/CMOS signal swing to safe levels before entering sensitive ADC or microcontroller inputs. IC Role / Device Role / Timing Role: Bidirectional clamping pair (anode-to-VCC, cathode-to-GND) protecting I/O pins against overvoltage. Use Value: 4 ns trr prevents latch-up during fast-rising ESD pulses; VF = 715 mV at 1 mA ensures minimal forward drop in low-current clamping. | Use Scenario: Rectifies RF envelope signals in 2.4 GHz ISM-band receiver front-ends for RSSI measurement. IC Role / Device Role / Timing Role: Zero-bias detector diode operating near zero-volt junction potential with minimal parasitic capacitance. Use Value: 1 pF Cd at 0 V reverse bias preserves Q-factor of matching network; low trr avoids harmonic distortion in envelope detection. |
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 |
|---|---|---|---|
| BAS16,115 | Same SOD523 package; trr = 4 ns but VR = 80 V (vs. 100 V); IF = 215 mA (vs. 250 mA) | Limited to ≤80 V rail applications; lower forward current margin in sustained pulse duty cycles | Select when 80 V VR suffices and legacy design reuse is prioritized over voltage headroom |
| 1N4148W,115 | SOD-123 package (larger: 3.7 × 1.6 mm); trr = 4 ns; VR = 100 V; IF = 300 mA; Cd = 4 pF | Higher capacitance degrades RF performance; larger footprint consumes 3× board area | Choose only if higher IF rating is required and layout space permits larger package |
Compared with BAS16,115 and 1N4148W,115, the BAS516,135 delivers superior voltage margin (100 V vs. 80 V), higher continuous forward current (250 mA vs. 215 mA), and smallest board footprint (1.2 × 0.8 mm), making it optimal for miniaturized, high-reliability signal-path switching where thermal and space constraints dominate.

FAQ
What is the maximum allowable junction temperature for BAS516,135?
The absolute maximum junction temperature (Tj) is 150 °C per Nexperia's Product Data Sheet. Operation above this limit risks permanent parametric shift or metallization failure. Derating is required above Tamb = 90 °C, as total power dissipation drops from 500 mW at Tsp ≤ 90 °C to lower values governed by Rth(j-sp) = 120 K/W and ambient thermal conditions.
Can BAS516,135 be used in place of BAS16 in existing designs?
Yes, with verification of voltage margin: BAS516,135 shares the same SOD523 package and 4 ns trr, but offers higher VR (100 V vs. 80 V) and IF (250 mA vs. 215 mA). Layout is identical, but system-level testing must confirm that increased reverse voltage rating does not affect clamping behavior in bidirectional configurations.
Is BAS516,135 suitable for automotive applications?
No - the datasheet explicitly states this is a non-automotive qualified product. It lacks AEC-Q101 qualification, automotive-grade reliability testing, and guaranteed operation across -40 °C to +125 °C extended temperature range. Automotive designs require Nexperia's automotive-grade equivalents such as PNE20010EP or BAS40-04W.
What reflow profile should be used for BAS516,135 soldering?
Follow JEDEC J-STD-020D for SOD523 packages: peak temperature 260 °C (≤10 s), ramp-up rate ≤3 °C/s, time above 217 °C = 60–150 s. The recommended footprint (Fig. 8) uses 0.5 mm × 0.4 mm solder pads with 0.6 mm spacing; avoid excessive solder paste volume to prevent bridging or tombstoning due to asymmetric thermal mass.
