Product details
Overview
BAV102,135 from Nexperia is a single general-purpose switching diode in a hermetically sealed glass SOD80C surface-mount package, rated for 150 V reverse voltage, ≤50 ns reverse recovery time, and 250 mA forward current. It serves as a high-speed clamping and polarity protection device in DC-DC converter feedback paths and low-voltage power rail switching circuits.
For engineers reviewing the BAV102,135 datasheet, BAV102,135 pinout, BAV102,135 application, or BAV102,135 equivalent, this diode is selected for fast transient response in compact power management designs where low capacitance (≤5 pF) and minimal leakage (<100 nA at 150 V) are critical to signal integrity and standby efficiency.
Technical Context
The BAV102,135 employs planar silicon technology optimized for rapid carrier recombination, enabling trr ≤50 ns under IF = 30 mA to IR = 30 mA switching with RL = 100 Ω. Its junction-to-ambient thermal resistance is 375 K/W on FR4 PCB, supporting operation up to 175 °C junction temperature.
Designed for unidirectional conduction, it exhibits VF = 1.0 V at IF = 100 mA and Cd = 5 pF at f = 1 MHz / VR = 0 V - parameters directly validated under IEC 60134 limiting value conditions and pulse-tested per tp ≤300 μs, δ ≤0.02.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 150 V - maximum continuous blocking capability in DC bias applications like reverse polarity protection. |
| Reverse Recovery Time (trr) | ≤50 ns - enables reliable operation in 1–5 MHz switching converters without tail current-induced losses. |
| Forward Voltage (VF) | 1.0 V @ 100 mA - low conduction loss supports efficiency in low-power rail clamping and signal routing. |
| Diode Capacitance (Cd) | ≤5 pF @ 1 MHz / 0 V - minimizes capacitive loading in high-frequency signal path and RF detector circuits. |
| Leakage Current (IR) | ≤100 nA @ 150 V - ensures stable biasing in high-impedance sensing nodes and battery-backed circuits. |
| Power Dissipation (Ptot) | 400 mW @ Tamb ≤25 °C - defines thermal derating envelope for SOD80C footprint on standard FR4 PCB. |
Pinout & Package
BAV102,135 uses the SOD80C hermetically sealed glass surface-mount package (3.3–3.7 mm length × 1.45–1.60 mm width × 0.3 mm height), with cathode identified by a marking band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to negative reference or return path; polarity-sensitive terminal for unidirectional current flow. |
| 2 | Anode | Connected to positive supply or signal source; forward conduction initiates when anode > cathode by ≥VF. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤50 ns enables use in 1–5 MHz DC-DC converters without compromising efficiency or EMI profile. |
| Low junction capacitance | Cd ≤5 pF preserves signal rise/fall times in RF detector and high-frequency clamp applications. |
| Hermetic glass SMD package | SOD80C construction provides moisture resistance and long-term reliability in industrial ambient conditions. |
| Low leakage at high temperature | IR ≤100 μA @ VR = 150 V / Tj = 150 °C maintains functionality in thermally stressed power rails. |
Applications
| DC-DC Converter Feedback Clamping | USB Port Reverse Polarity Protection |
|---|---|
Use Scenario: Clamp feedback node voltage during startup transients in isolated flyback or buck-boost converters. IC Role / Device Role: Fast-switching clamping diode placed between optocoupler input and auxiliary winding. Use Value: ≤50 ns trr prevents false triggering of regulation loop; 150 V VR rating covers reflected surge peaks up to 120 V. |
Use Scenario: Block reverse current from miswired USB cables in embedded host controllers. IC Role / Device Role: Series-connected polarity guard on VBUS line before LDO or USB switch IC. Use Value: ≤100 nA IR at 5 V ensures <1 μW standby loss; SOD80C footprint fits tight board space near connector. |
| Low-Voltage Signal Routing | EMI Filter Snubber Network |
Use Scenario: Isolate analog sensor outputs from shared microcontroller ADC inputs in multi-channel systems. IC Role / Device Role: Passive OR-ing diode in multiplexed signal path with minimal forward drop. Use Value: VF = 1.0 V @ 100 mA avoids ADC reference shift; 5 pF Cd prevents high-frequency crosstalk. |
Use Scenario: Dampen ringing in LC filter sections of motor drive gate driver supplies. IC Role / Device Role: Snubber diode paired with RC network across inductive choke. Use Value: 250 mA IF rating handles transient energy; 375 K/W Rth(j-a) allows self-cooling without heatsink. |
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 |
|---|---|---|---|
| BAV103,135 | Higher VR = 200 V; identical trr, Cd, and package | Required where system surge tolerance exceeds 150 V (e.g., 24 V industrial bus with ±100 V transients) | Select BAV103,135 only if reverse voltage margin >50 V is mandated; otherwise BAV102,135 offers tighter cost and inventory control. |
| 1N4148W,115 | Same SOD-123 package; VR = 100 V; trr = 4 ns (faster); Cd = 4 pF | Better for <1 MHz digital logic clamping but insufficient for 150 V rail protection | Choose 1N4148W,115 only for low-voltage, ultra-fast signal steering; not suitable as drop-in replacement for 150 V blocking. |
Compared with BAV102,135, the BAV103,135 extends reverse voltage headroom without trade-offs in speed or size, while the 1N4148W,115 sacrifices blocking capability for nanosecond-level switching - making each alternative optimal only within distinct voltage/speed design constraints.

FAQ
What is the maximum junction temperature for continuous operation of BAV102,135?
The absolute maximum junction temperature is 175 °C, validated per IEC 60134 limiting values. Operation at this temperature requires strict thermal design: Ptot must be derated to zero above Tamb = 25 °C using Rth(j-a) = 375 K/W, and sustained 175 °C operation is only permissible with verified PCB copper area and airflow.
Is BAV102,135 suitable for automotive applications?
No - BAV102,135 is not automotive-qualified. The datasheet explicitly states it is "non-automotive qualified" and lacks AEC-Q101 stress testing, PPAP documentation, or guaranteed operation over −40 °C to +125 °C extended temperature range required for automotive ECUs or infotainment systems.
How does the SOD80C package differ from SOD-123 in mechanical and thermal performance?
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 has higher thermal resistance (Rth(j-a) = 375 K/W vs. ~250 K/W for SOD-123) but superior moisture resistance and long-term stability due to glass encapsulation.
Can BAV102,135 replace BAT54 series Schottky diodes in low-VF applications?
No - BAV102,135 is a PN junction diode with VF ≈ 1.0 V at 100 mA, whereas BAT54 Schottkys achieve VF ≈ 0.3 V. Substituting would increase conduction loss by >2× and raise junction temperature; BAV102,135 is not a Schottky and lacks its low-forward-drop advantage.
