Product details
Overview
BAV103,135 from Nexperia is a single high-speed silicon 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 in voltage clamping, reverse polarity protection, and general-purpose signal switching circuits on FR4 PCBs.
For engineers reviewing the BAV103,135 datasheet, BAV103,135 pinout, BAV103,135 application, or BAV103,135 equivalent, this page delivers verified electrical parameters, thermal limits, SOD80C footprint details, and real-world use cases for fast-switching discrete diode selection in industrial and consumer power management designs.
Technical Context
This planar-technology diode operates as a unidirectional switch with low capacitance (≤5 pF at 1 MHz, 0 V) and minimal leakage (≤100 nA at 200 V, 25 °C), enabling clean signal integrity in high-frequency clamp and flyback snubber paths. Its 50 ns trr supports operation up to ~10 MHz switching frequencies under defined pulse conditions (tp ≤300 μs, δ ≤0.02).
Thermal performance is defined for FR4 PCB mounting: junction-to-ambient thermal resistance is 375 K/W in free air, and maximum junction temperature is 175 °C. Derating curves confirm usable forward current down to 100 mA at 150 °C ambient, supporting reliable operation in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 200 V - maximum DC or repetitive peak reverse bias before breakdown; defines clamping headroom in protection circuits. |
| trr (Reverse Recovery Time) | ≤50 ns - measured at IF/IR = 30 mA, RL = 100 Ω, IR = 3 mA; enables efficient high-frequency switching without excessive switching loss. |
| Cd (Diode Capacitance) | ≤5 pF at 1 MHz, 0 V - minimizes signal coupling and timing skew in RF or fast digital signal routing. |
| IF (Forward Current) | 250 mA continuous - maximum steady-state conduction capability at Tamb ≤25 °C; derates linearly above 25 °C. |
| VF (Forward Voltage) | 1.25 V at IF = 200 mA - determines conduction loss and self-heating in series-switching applications. |
| IR (Reverse Leakage) | ≤100 nA at VR = 200 V, 25 °C - ensures low standby power in battery-backed or high-impedance sensing paths. |
| Ptot (Power Dissipation) | 400 mW at Tamb ≤25 °C - sets thermal design boundary for trace width and copper area on standard FR4. |
Pinout & Package
The BAV103,135 is housed in a hermetically sealed glass SOD80C package (3.3–3.7 mm length, 1.45–1.60 mm width, 0.3 mm height), optimized for reflow and wave soldering on standard FR4 PCBs with tin-plated copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Marked end of device; connects to higher-potential node during reverse bias; carries return current in forward conduction. |
| 2 | Anode | Unmarked end; connects to lower-potential node during forward bias; source of forward current flow. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤50 ns enables use in >5 MHz clock line clamping and SMPS snubber networks without oscillation. |
| Low junction capacitance | 5 pF at 0 V reverse bias preserves signal edge rate in high-speed data line protection (e.g., USB D+/D−). |
| Hermetic glass SMD package | SOD80C construction ensures long-term moisture resistance and stable parametric performance over 10+ year field life. |
| Low leakage current | 100 nA max at 200 V allows integration into high-impedance analog monitoring circuits without offset drift. |
Applications
| DC Power Input Protection | Digital Signal Clamping |
|---|---|
Use Scenario: Reverse polarity protection on 12 V/24 V industrial sensor inputs. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-load; blocks reverse voltage while passing forward current. Use Value: Prevents damage to downstream LDOs or microcontrollers during accidental battery reversal, with <1.25 V forward drop at 200 mA. |
Use Scenario: ESD and overvoltage clamping on UART TX/RX lines in embedded gateways. IC Role / Device Role / Timing Role: Cathode-to-rail, anode-to-signal; shunts transients >200 V to ground or supply rail. Use Value: 5 pF capacitance avoids signal degradation at 115.2 kbps baud rates; 50 ns trr ensures fast transient response. |
| SMPS Snubber Network | High-Frequency Oscillator Biasing |
Use Scenario: RC snubber across flyback transformer primary in 100 kHz–500 kHz AC/DC adapters. IC Role / Device Role / Timing Role: Fast-recovery path for leakage inductance energy; placed in series with snubber capacitor. Use Value: 50 ns trr prevents reverse conduction delay that would increase switching loss and MOSFET stress. |
Use Scenario: Bias feed and harmonic suppression in Colpitts oscillator circuits for ISM-band transmitters. IC Role / Device Role / Timing Role: DC blocking and RF isolation between active device and tank circuit. Use Value: Low 5 pF capacitance avoids pulling oscillator frequency; 200 V rating withstands RF voltage peaks. |
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 |
|---|---|---|---|
| BAV102,115 | 150 V VR rating (vs. 200 V); identical trr, Cd, and package. | Limited to ≤150 V clamping or protection; unsuitable where 200 V margin is required. | Select when system reverse voltage stays below 150 V and cost optimization is prioritized. |
| 1N4148W,115 | 100 V VR; 4 ns trr (faster); 4 pF Cd; same SOD-123 package (not SOD80C). | Better for ultra-fast logic-level clamping but lower voltage rating; different footprint requires layout change. | Choose only if speed is critical and VR ≤100 V; verify PCB land pattern compatibility. |
Compared with BAV103,135, BAV102,115 trades 50 V reverse voltage headroom for identical speed and footprint, while 1N4148W,115 offers faster recovery but demands layout revision and sacrifices 100 V clamping margin.

FAQ
What is the maximum junction temperature for BAV103,135?
The absolute maximum junction temperature is 175 °C, as specified in IEC 60134 limiting values. Operation above this threshold risks permanent parametric shift or catastrophic failure. Thermal design must ensure Tj remains within limit using the published Rth(j-a) = 375 K/W and derating curves.
Is BAV103,135 suitable for automotive applications?
No - the BAV103,135 is not automotive-qualified. The datasheet explicitly states it is "non-automotive qualified" and has not undergone AEC-Q101 testing or qualification per automotive reliability standards. Use only in industrial, consumer, or computing applications.
How does the SOD80C package differ from SOD-123?
SOD80C is a smaller, hermetically sealed glass package (3.3–3.7 mm × 1.45–1.60 mm) with tighter dimensional tolerances and superior moisture resistance; SOD-123 is a larger plastic package (3.7 mm × 1.6 mm) with different land pattern and thermal characteristics. They are not footprint-compatible.
What test conditions define the 50 ns trr specification?
The reverse recovery time is measured under defined pulse conditions: switching from IF = 30 mA to IR = 30 mA with RL = 100 Ω, and sampling at IR = 3 mA. Pulse width is ≤300 μs with duty cycle ≤0.02, per IEC 60747-2 test methodology.
