Product details

Overview

BAV20WS-7-F from Diodes Incorporated is a surface-mount high-voltage fast-switching diode in SOD323 package, rated for 200 V repetitive peak reverse voltage (V_RRM), 250 mA forward continuous current (I_FM), and 50 ns reverse recovery time (t_RR). It serves as a general-purpose switching diode in power supply clamp, signal routing, and protection circuits across industrial and consumer electronics.

For engineers reviewing the BAV20WS-7-F datasheet, BAV20WS-7-F pinout, BAV20WS-7-F application, or BAV20WS-7-F equivalent, key selection criteria include its 200 V V_RRM, 1.25 V max forward voltage at 200 mA, 100 nA max reverse leakage at 150 V, 5.0 pF junction capacitance, and SOD323 footprint compatibility with automated assembly.

Technical Context

This diode employs a planar epitaxial silicon structure optimized for fast recovery and high-voltage blocking. Its 50 ns t_RR enables use in medium-frequency switching (up to ~1 MHz) without excessive switching loss, while the 200 V V_RRM supports operation in 12–48 V system rails with margin.

The device operates across –55 °C to +150 °C and dissipates up to 200 mW at 25 °C ambient, derating linearly above 25 °C per the 625 °C/W R_θJA. Its cathode-band-marked SOD323 package ensures unambiguous polarity identification during placement and inspection.

Key Specifications

Applications

Power Supply Clamp

Signal-Level Protection

Use Scenario: Clamping inductive kickback from relay coils or solenoids in 24 V industrial control modules.

IC Role / Device Role / Timing Role: Fast-recovery diode providing low-loss freewheeling path during switch-off.

Use Value: 50 ns t_RR minimizes voltage overshoot; 200 V V_RRM accommodates 2× nominal rail voltage spikes.

Use Scenario: ESD and transient protection on analog sensor inputs (e.g., thermistor or RTD lines).

IC Role / Device Role / Timing Role: Passive clamping diode limiting input voltage to safe levels relative to supply rails.

Use Value: 100 nA I_R at 150 V prevents loading of high-impedance sensor outputs.

DC-DC Converter Snubber

Logic-Level Signal Steering

Use Scenario: RC-snubber network across MOSFET drain-source in flyback converter primary side.

IC Role / Device Role / Timing Role: Fast-recovery diode absorbing high-dV/dt ringing during switching transitions.

Use Value: 5.0 pF C_T limits capacitive coupling into snubber resistor, preserving damping effectiveness.

Use Scenario: OR-ing logic for dual-supply redundancy in embedded microcontroller power domains.

IC Role / Device Role / Timing Role: Low-forward-drop diode enabling automatic source selection without active control.

Use Value: 1.25 V V_F max at 200 mA ensures <250 mW dissipation under full load, avoiding thermal runaway.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage fast-switching diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAV21WS-7-F	250 V V_RRM, 1.7 A I_FSM, same SOD323 package and t_RR	Higher voltage margin; lower surge rating than BAV20WS	Select when system transients exceed 200 V but average current remains ≤200 mA
1N4148WS-7-F	100 V V_RRM, 4 A I_FSM, identical SOD323 footprint	Lower voltage rating; higher surge tolerance	Choose for ≤75 V rails where robustness against short pulses is prioritized over blocking capability

Compared with BAV21WS-7-F and 1N4148WS-7-F, the BAV20WS-7-F offers optimal balance of 200 V blocking, 50 ns speed, and 250 mA current handling-making it ideal for 24–48 V industrial power interfaces where both voltage margin and switching fidelity matter.

FAQ

What is the maximum operating temperature for BAV20WS-7-F?

The BAV20WS-7-F is rated for junction and storage temperatures from –55 °C to +150 °C. Its thermal resistance junction-to-ambient is 625 °C/W on standard FR-4 with 1-inch² copper pad, meaning derating begins above 25 °C ambient to maintain safe junction temperature under load.

Is BAV20WS-7-F suitable for automotive applications?

BAV20WS-7-F is not AEC-Q200 qualified. For automotive use, Diodes offers the Q-suffix variant BAV20WSQ-7-F, which is PPAP-capable and manufactured in IATF 16949-certified facilities-required for safety-critical or mission-critical vehicle subsystems.

How does the SOD323 package affect PCB layout?

The SOD323 footprint requires precise pad geometry: 0.30 mm wide × 1.20 mm long lands with 0.70 mm center-to-center spacing. Its 0.95 mm height allows stacking under connectors or shields, and the cathode band must align with silkscreen polarity indicators to prevent assembly errors.

What is the typical reverse recovery behavior under pulsed conditions?

At I_F = I_R = 30 mA, I_RR = 0.1 × I_R, and R_L = 100 Ω, the BAV20WS-7-F exhibits ≤50 ns reverse recovery time. This value holds across –40 °C to +125 °C, with minor increase (<10%) at elevated temperature due to carrier lifetime effects.
