Product details
Overview
BAS516,115 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 BAS516,115 datasheet, BAS516,115 pinout, BAS516,115 application, or BAS516,115 equivalent, key selection criteria include trr ≤ 4 ns, VR ≤ 100 V, IF = 250 mA (Tamb = 25 °C), Cd = 1 pF at 0 V, and ultra-small SOD523 footprint compatibility with high-density PCB layouts.
Technical Context
The BAS516,115 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. Its junction design yields low leakage (IR ≤ 0.5 µA at VR = 80 V, Tamb = 25 °C) and stable VF characteristics across temperature.
Thermal resistance from junction to solder point is 120 K/W, with maximum junction temperature rated at 150 °C. The device operates within –65 °C to +150 °C ambient and storage ranges, and its SOD523 package supports reflow soldering per JEDEC J-STD-020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking range in flyback snubbers and level-shift clamps. |
| trr | 4 ns - Measured at IF = 10 mA, IR = 10 mA, RL = 100 Ω; enables >100 MHz switching in RF detector and pulse shaping circuits. |
| VF | 855 mV at IF = 10 mA - Low forward drop minimizes conduction loss in low-voltage signal routing and bias networks. |
| Cd | 1 pF at VR = 0 V, f = 1 MHz - Ultra-low capacitance preserves signal integrity in high-frequency sampling gates and ESD protection paths. |
| IR | 0.5 µA at VR = 80 V, Tamb = 25 °C - Ensures negligible leakage in battery-backed hold-up and precision reference divider applications. |
| Ptot | 500 mW at Tsp ≤ 90 °C - Power dissipation limit governs thermal derating on FR4 PCBs with single-sided copper and standard footprint. |
Pinout & Package
Encapsulated in SOD523 (SC-79) plastic surface-mount package: 1.2 mm × 0.8 mm × 0.6 mm body, 2-terminal configuration, cathode tab solder point.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to internal P-region; must be held at lower potential than anode during forward conduction; solder point serves as primary thermal path. |
| 2 | Anode (A) | Connected to internal N-region; supplies forward current path; electrically isolated from cathode tab in layout. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal tail current in PWM edge detection and synchronous rectifier control timing. |
| Low junction capacitance | Cd = 1 pF at 0 V enables use in >500 MHz RF envelope detectors without signal attenuation. |
| Ultra-compact SMD package | SOD523 footprint (1.2 × 0.8 mm) allows placement adjacent to QFN ICs without trace stubs or routing congestion. |
| Low leakage at high reverse bias | IR ≤ 0.5 µA at VR = 80 V maintains accuracy in high-impedance voltage monitoring and analog sample-hold circuits. |
Applications
| USB 2.0 Data Line Protection | DC-DC Converter Feedback Clamp |
|---|---|
Use Scenario: Bidirectional ESD and overvoltage transient suppression on D+ and D− lines of USB 2.0 ports without degrading 480 Mbps signal integrity. IC Role / Device Role / Timing Role: Signal-path clamping diode placed between data line and VBUS or GND, operating in reverse-biased blocking mode until transient exceeds VR. Use Value: 1 pF capacitance prevents rise-time degradation; 4 ns trr avoids latch-up during fast transients; 100 V VRRM withstands common-mode surges. | Use Scenario: Fast clamping of optocoupler feedback signals in isolated 500 kHz flyback converters to prevent regulation overshoot during load steps. IC Role / Device Role / Timing Role: High-speed shunt clamp across optocoupler output to limit voltage excursion during transient events. Use Value: Sub-4 ns recovery ensures accurate duty-cycle capture; low VF (855 mV) minimizes offset in error amplifier input stage. |
| Logic-Level Signal Translation | RF Detector Input Stage |
Use Scenario: Level shifting between 3.3 V microcontroller GPIO and 5 V peripheral interface, using diode-resistor pull-up topology. IC Role / Device Role / Timing Role: Forward-conducting voltage translator that drops ~0.85 V to shift logic thresholds while maintaining nanosecond edge fidelity. Use Value: 4 ns trr preserves clean transitions up to 100 MHz; low IR ensures no DC loading on high-Z inputs. | Use Scenario: Envelope detection of 900 MHz ISM-band signals in wireless sensor node receivers. IC Role / Device Role / Timing Role: Zero-bias RF detector diode converting RF amplitude to baseband voltage via square-law conduction. Use Value: 1 pF Cd maximizes RF coupling efficiency; low series resistance enables sensitivity down to –20 dBm input. |
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 | VRRM = 80 V; trr = 4 ns; Cd = 2 pF; SOD-123 package (2.7 × 1.6 mm) | Larger footprint; higher capacitance limits use above 200 MHz | Select when board space permits larger package and 80 V rating suffices. |
| 1N4148W,115 | VRRM = 100 V; trr = 4 ns; Cd = 4 pF; SOD-123 package | Higher capacitance reduces bandwidth in RF and high-speed digital paths | Prefer only where cost sensitivity outweighs RF performance requirements. |
Compared with BAS16,115 and 1N4148W,115, the BAS516,115 delivers identical trr but achieves 1 pF capacitance and SOD523 size-critical for miniaturized USB, wearables, and mmWave front-end designs where parasitic capacitance and board area constrain performance.

FAQ
What is the maximum continuous forward current rating for BAS516,115?
The BAS516,115 is rated for 250 mA continuous forward current at Tamb = 25 °C when mounted on an FR4 PCB with single-sided copper and standard SOD523 footprint. Derating applies above 25 °C ambient, reaching zero at 150 °C junction temperature per thermal resistance of 120 K/W.
Does BAS516,115 support lead-free reflow soldering?
Yes, the BAS516,115 is qualified for lead-free reflow soldering per JEDEC J-STD-020. Its SOD523 package withstands peak temperatures up to 260 °C for 30 seconds, and the recommended footprint uses 0.4 mm wide solder lands with 0.5 mm spacing per Nexperia's SOD523_FR drawing.
How does the 1 pF capacitance impact high-frequency circuit design?
The 1 pF diode capacitance at 0 V reverse bias minimizes signal reflection and phase distortion in >500 MHz paths. In RF detector applications, it enables efficient coupling without external matching; in high-speed digital clamps, it avoids rounding of 1–2 ns edges typical in USB 2.0 and LVDS signaling.
Can BAS516,115 replace BAS16 in existing designs?
Direct replacement requires layout revision due to SOD523 (1.2 × 0.8 mm) vs. SOD-123 (2.7 × 1.6 mm) footprint mismatch. Electrically, BAS516,115 offers superior Cd (1 pF vs. 2 pF) and same trr, but VRRM is identical at 100 V-no electrical redesign needed if mechanical adaptation is feasible.
