Product details
Overview
BAV103,115 from Nexperia is a single general-purpose switching diode in a hermetically sealed glass SOD80C surface-mount package, featuring 200 V reverse voltage rating, ≤50 ns reverse recovery time, ≤5 pF capacitance, and 250 mA forward current capability-used for high-speed clamping and polarity protection in DC-DC converter feedback paths and USB port interface circuits.
For engineers reviewing the BAV103,115 datasheet, BAV103,115 pinout, BAV103,115 application, or BAV103,115 equivalent, this page delivers verified electrical parameters, validated SOD80C terminal mapping, real-world use cases in power rail protection and signal line clamping, and confirmed alternative diodes with documented voltage/recovery trade-offs.
Technical Context
This planar silicon diode operates as a unidirectional switch with fast turn-off behavior enabled by low minority-carrier lifetime design. Its 200 V VR rating supports operation across 12 V–48 V industrial bus systems, while the 50 ns trr enables reliable performance in 1–5 MHz switching node snubbing.
Thermal resistance of 375 K/W (junction-to-ambient, free air) and 400 mW total power dissipation at Tamb ≤25 °C define its derating envelope on FR4 PCBs with standard footprint. Reverse leakage remains ≤100 nA at 200 V and 25 °C, critical for low-power standby circuit integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 200 V - Maximum continuous reverse blocking voltage before breakdown; sets upper limit for clamping in 24 V/48 V power rails. |
| trr | ≤50 ns - Measured at IF = IR = 30 mA, RL = 100 Ω; ensures minimal switching loss in high-frequency rectification up to 5 MHz. |
| Cd | ≤5 pF at f = 1 MHz, VR = 0 V - Low junction capacitance preserves signal edge integrity in ESD-coupled data lines like RS-485 or CAN transceiver bias networks. |
| IF | 250 mA continuous - Rated forward current under standard FR4 PCB mounting; supports load-switching in auxiliary 3.3 V/5 V supply monitoring paths. |
| VF | 1.25 V at IF = 200 mA - Forward voltage drop determines conduction loss in reverse-polarity protection circuits; impacts thermal rise in compact layouts. |
| IR | ≤100 nA at VR = 200 V, Tj = 25 °C - Ultra-low leakage maintains accuracy in high-impedance voltage divider or reference bias networks. |
Pinout & Package
The BAV103,115 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 soldering on FR4 PCBs with standard 2.30 mm × 4.30 mm land pattern per Nexperia's footprint guide.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to higher potential during reverse bias; marking band identifies this terminal for correct orientation in clamping configurations. |
| 2 | Anode | Connected to lower potential during forward conduction; ties to ground or return path in reverse polarity protection schemes. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | 50 ns trr enables clean turn-off in 1–5 MHz DC-DC converter synchronous rectifier snubbers without ringback overshoot. |
| Low junction capacitance | 5 pF Cd minimizes capacitive loading on high-impedance analog sense nodes, preserving bandwidth in voltage monitor feedback loops. |
| Hermetic glass SMD package | SOD80C construction provides moisture resistance and long-term parameter stability in humid industrial environments (−65 °C to +175 °C Tstg). |
| Low leakage current | 100 nA IR at 200 V ensures <1 μA total leakage in series-connected protection strings, critical for battery-backed real-time clock circuits. |
Applications
| DC-DC Converter Output Clamping | USB Port Reverse Polarity Protection |
|---|---|
|
Use Scenario: Suppressing flyback voltage spikes at the output of non-isolated buck converters driving solenoid loads. IC Role / Device Role / Timing Role: Fast-recovery diode placed across output inductor to clamp inductive kickback within safe VR margin. Use Value: 50 ns trr prevents energy trapping and secondary oscillation, reducing EMI emissions by >6 dBμV in 30–100 MHz band. |
Use Scenario: Preventing damage to downstream USB controller ICs when external 5 V power is connected with reversed polarity. IC Role / Device Role / Timing Role: Series anode-to-VBUS diode that blocks reverse current while passing normal 5 V supply with minimal drop. Use Value: 1.25 V VF at 200 mA limits insertion loss to <2.5% of nominal 5 V rail, maintaining USB 2.0 signaling margin. |
| RS-485 Transceiver Bias Network | Industrial Sensor Signal Line Clamping |
|
Use Scenario: Providing fail-safe bias to RS-485 differential bus lines in open-circuit or idle states. IC Role / Device Role / Timing Role: Diode pair (anode-to-A, cathode-to-B) establishing defined logic state when no driver is active. Use Value: 5 pF Cd avoids signal distortion on 10 Mbps RS-485 links; 200 V VR withstands common-mode surges up to ±1 kV. |
Use Scenario: Protecting analog input pins of 24-bit delta-sigma ADCs in vibration sensor modules exposed to ESD events. IC Role / Device Role / Timing Role: Low-capacitance clamping diode shunting transient energy from sensor output to AVDD or AGND rails. Use Value: 100 nA IR prevents DC offset shift in 10 MΩ input impedance front-end; 50 ns trr clears transients before ADC sampling window. |
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, identical trr (≤50 ns), same SOD80C package | Not suitable for 200 V+ clamping; limited to 12 V–24 V systems | Select when system max reverse voltage ≤150 V and cost sensitivity outweighs voltage headroom needs. |
| 1N4148W,115 | 100 V VR, 4 ns trr, SOD-123 package, higher IF (300 mA) | Better speed but lower voltage rating; larger thermal resistance (420 K/W) | Prefer for <100 V, >10 MHz signal routing where ultra-fast recovery outweighs voltage margin. |
Compared with BAV103,115, BAV102,115 sacrifices 50 V reverse margin for identical speed in the same footprint, while 1N4148W,115 trades 100 V lower VR for 12× faster trr-making BAV103,115 optimal for 48 V industrial power rail clamping where voltage robustness and moderate speed are jointly essential.

FAQ
What is the maximum junction temperature for continuous operation of BAV103,115?
The absolute maximum junction temperature (Tj) is 175 °C, validated per IEC 60134 limiting values. Operation at this temperature requires strict thermal management: derated forward current to ≤120 mA at Tamb = 100 °C per Figure 5, and PCB copper area ≥40 mm² per side under the SOD80C footprint to maintain Rth(j-a) ≤375 K/W.
Can BAV103,115 be used in automotive applications?
No-BAV103,115 is not automotive-qualified. The datasheet explicitly states it is "non-automotive qualified" and lacks AEC-Q101 stress testing, PPAP documentation, or guaranteed operation across −40 °C to +125 °C extended temperature range. It is rated for −65 °C to +175 °C storage but not automotive-grade reliability or failure rate reporting.
How does the SOD80C package differ from SOD-123 in mechanical and thermal terms?
SOD80C is a smaller hermetically sealed glass package (3.3–3.7 mm × 1.45–1.60 mm) versus SOD-123's plastic body (3.7 mm × 1.6 mm). SOD80C offers superior moisture resistance and tighter parameter stability over temperature but has higher thermal resistance (375 K/W vs. ~300 K/W for SOD-123) due to glass encapsulation and smaller copper pad contact area.
Is the 50 ns reverse recovery time guaranteed across all operating conditions?
Yes-the 50 ns trr is a maximum specification measured under defined test conditions: IF = IR = 30 mA, RL = 100 Ω, and measurement at IR = 3 mA (per datasheet footnote [2]). It is not guaranteed at higher currents or elevated temperatures; at Tj = 125 °C, typical trr increases to ~75 ns, and maximum may exceed 100 ns.
