Product details
Overview
BAV103/S500,115 from Nexperia is a single general-purpose switching diode in a hermetically sealed glass SOD80C surface-mount package, rated for 200 V reverse voltage, ≤50 ns reverse recovery time, and 250 mA forward current - used for high-speed clamping and polarity protection in DC power rails and signal conditioning circuits.
For engineers reviewing the BAV103/S500,115 datasheet, BAV103/S500,115 pinout, BAV103/S500,115 application, or BAV103/S500,115 equivalent, key selection criteria include verified trr ≤50 ns at IF = 30 mA → IR = 30 mA, Cd ≤5 pF at 1 MHz/0 V, and thermal resistance Rth(j-a) = 375 K/W on FR4 PCB - critical for compact power-supply snubbers and ESD-protected I/O stages.
Technical Context
The BAV103/S500,115 employs planar silicon technology to achieve fast switching with low stored charge, enabling clean turn-off in pulse-width modulated (PWM) feedback paths and flyback snubber networks. Its 200 V VR rating supports operation across 12 V–48 V industrial bus systems.
Designed for surface-mount assembly on standard FR4 PCBs with tin-plated copper, it delivers stable performance up to 175 °C junction temperature and maintains <100 nA reverse leakage at VR = 200 V and Tj = 25 °C - essential for low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 200 V maximum reverse voltage - supports 48 V nominal power rails with 4× safety margin against transients |
| trr | ≤50 ns reverse recovery time - enables reliable operation up to ~10 MHz switching frequencies in snubbers |
| Cd | ≤5 pF diode capacitance at 1 MHz/0 V - minimizes signal distortion in RF-coupled detection paths |
| IF | 250 mA continuous forward current - sufficient for LED biasing and logic-level clamping in microcontroller I/O |
| IR | ≤100 nA reverse leakage at VR = 200 V and Tj = 25 °C - preserves battery life in always-on sensor nodes |
| Ptot | 400 mW total power dissipation at Tamb ≤25 °C - allows operation without heatsinking in space-constrained modules |
| Rth(j-a) | 375 K/W thermal resistance (free air) - defines derating to 150 mA at 70 °C ambient per Fig 5 |
Pinout & Package
Hermetically sealed glass SOD80C package: 3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height; cathode marked by band; optimized for reflow and wave soldering per IPC-7351B footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to negative rail or signal return; marking band identifies this terminal for correct orientation during placement |
| 2 | Anode | Connected to positive supply or signal source; forward conduction path starts here when biased above VF ≈1.0 V at 100 mA |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤50 ns ensures minimal tail current in PWM gate-drive snubbers, reducing MOSFET switching losses |
| Low junction capacitance | Cd ≤5 pF avoids loading of high-impedance analog inputs in precision comparator clamp circuits |
| Hermetic glass SMD package | SOD80C construction provides moisture resistance and long-term reliability in humid industrial environments |
| Low leakage current | IR ≤100 nA at 200 V enables use in ultra-low-power battery monitoring shunt paths |
| Wide temperature range | −65 °C to +175 °C operating/storage range supports deployment in automotive under-hood and industrial motor-control enclosures |
Applications
| DC Power Rail Clamping | Reverse Polarity Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar general-purpose switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV102/S500,115 | 150 V VR, identical trr ≤50 ns and Cd ≤5 pF; same SOD80C package and pinout | Not suitable for 200 V clamping; limited to 12–24 V systems with lower surge margins | Select when design operates below 150 V reverse stress and cost sensitivity outweighs voltage headroom needs |
| 1N4148W-7-F | 100 V VR, trr ≤4 ns (faster), Cd ≤4 pF, SOD-123 package (larger footprint, higher Rth(j-a)) | Better for <1 MHz high-frequency signal routing; unsuitable for 200 V power-rail clamping | Prefer where nanosecond-level switching dominates over voltage rating - e.g., clock line steering or sample-and-hold discharge |
Compared with BAV103/S500,115, the BAV102/S500,115 trades 50 V reverse voltage headroom for identical speed and footprint, while the 1N4148W-7-F offers superior speed in a less thermally efficient package - making BAV103/S500,115 optimal for 200 V–rated industrial snubbers requiring balanced speed, voltage, and thermal performance.

The BAV103/S500,115 has a maximum repetitive peak reverse voltage (VRRM) of 250 V and a DC reverse voltage (VR) rating of 200 V. This makes the BAV103/S500,115 suitable for clamping applications in 48 V industrial systems where transient suppression up to 200 V is required without breakdown.
Does BAV103/S500,115 have a specified reverse recovery time?
Yes, the BAV103/S500,115 has a guaranteed maximum reverse recovery time (trr) of 50 ns under conditions of IF = 30 mA switching to IR = 30 mA with RL = 100 Ω and measurement at IR = 3 mA. This parameter is confirmed in Table 2 and Table 8 of the official Nexperia datasheet for BAV103/S500,115.
What package type does BAV103/S500,115 use?
The BAV103/S500,115 uses the SOD80C package - a small hermetically sealed glass surface-mount device with 2-pin configuration, 3.3–3.7 mm body length, and cathode identified by a visible band. Its outline and soldering footprints are fully documented in Figures 8–10 of the Nexperia datasheet.
Is BAV103/S500,115 suitable for high-temperature environments?
Yes, the BAV103/S500,115 is rated for junction temperatures up to 175 °C and storage/ambient temperatures from −65 °C to +175 °C. Its thermal resistance Rth(j-a) = 375 K/W (free air) and derating curve in Figure 5 confirm reliable operation in enclosed industrial enclosures and under-hood automotive auxiliary modules.
How does BAV103/S500,115 compare to BAV102 in terms of voltage rating?
The BAV103/S500,115 is rated for 200 V reverse voltage (VR), whereas the BAV102 is rated for 150 V. Both share identical trr ≤50 ns, Cd ≤5 pF, and SOD80C packaging.
