Product details
Overview
BAV20W-7-F from Diodes Incorporated is a surface-mount fast-switching silicon switching diode in SOD-123 package, rated for 200 V peak repetitive reverse voltage (VRRM), 400 mA forward current (IF), and 50 ns reverse recovery time (tRR), used in general-purpose switching, clamp, and protection circuits in power supplies and signal routing.
For engineers reviewing the BAV20W-7-F datasheet, BAV20W-7-F pinout, BAV20W-7-F application, or BAV20W-7-F equivalent, key selection criteria include reverse breakdown voltage margin, switching speed under 30 mA test conditions, thermal resistance (500 °C/W), cathode-band polarity marking, and lead-free SOD-123 footprint compatibility with automated assembly.
Technical Context
This diode operates as a unidirectional voltage-controlled switch with low forward voltage drop (≤1.25 V at 200 mA) and high DC blocking capability up to 150 V (VR). Its 50 ns tRR enables use in moderate-frequency (<1 MHz) switching applications where charge storage and minority-carrier lifetime are critical.
The device features a molded plastic SOD-123 case rated UL 94V-0, moisture sensitivity level 1, and matte tin-plated alloy 42 leads. It is fully RoHS-compliant, halogen- and antimony-free ("Green"), and designed for commercial-grade operation from –55 °C to +150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - supports DC blocking in 12–48 V power rails with ≥33 % safety margin |
| IF | 400 mA continuous - suitable for low-power signal switching and logic-level clamping |
| tRR | 50 ns - enables reliable operation in 100 kHz–1 MHz flyback snubbers and pulse shaping |
| VF | 1.25 V @ 200 mA - limits conduction loss to ≤250 mW in typical forward-biased configurations |
| CT | 5.0 pF @ 0 V - minimizes capacitive loading in high-impedance signal paths and RF detector inputs |
| RθJA | 500 °C/W - requires minimal copper area on FR-4 PCB for thermal management at full IF |
Pinout & Package
Package: SOD-123 - surface-mount plastic case (1.55 mm × 2.65 mm × 0.95 mm), cathode band marked, moisture sensitivity level 1, UL 94V-0 rated.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node in forward bias; must be routed with low-inductance trace for fast switching |
| Cathode (marked) | Forward current exit / reverse-blocking terminal | Cathode band identifies polarity; ties to higher-potential node or ground return in clamp configurations |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching speed | 50 ns reverse recovery time ensures minimal tail current and reduced switching loss in 100 kHz–1 MHz circuits |
| High reverse breakdown voltage | 200 V VRRM provides robust surge immunity in 24 V industrial control and telecom line interfaces |
| Surface-mount SOD-123 package | Standardized footprint compatible with high-speed pick-and-place and reflow profiles (J-STD-020 Level 1) |
| Lead-free & Green compliance | Halogen- and antimony-free construction meets automotive and industrial environmental mandates without derating |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148W-7-F | VRRM = 100 V, tRR = 4 ns, IF = 300 mA | Better speed but lower voltage rating; unsuitable for >100 V clamping | Select when sub-10 ns recovery is required and system voltage stays ≤75 V. |
| BAV21W-7-F | VRRM = 250 V, tRR = 50 ns, same package and thermal specs | Higher voltage margin with identical layout and thermal behavior | Choose for 48 V+ systems needing extra reverse standoff without footprint change. |
Compared with BAV20W-7-F, the 1N4148W-7-F trades voltage headroom for ultrafast recovery, while the BAV21W-7-F extends blocking capability without altering board space or thermal design-making it a direct upgrade for higher-voltage reliability.

FAQ
What is the maximum operating temperature for BAV20W-7-F?
The BAV20W-7-F is rated for junction and storage temperatures from –55 °C to +150 °C. Its thermal resistance of 500 °C/W means that at 400 mA forward current and ambient temperature of 70 °C, junction temperature remains within safe limits when mounted per recommended pad layout on FR-4 PCB.
Is BAV20W-7-F suitable for automotive applications?
No-BAV20W-7-F is a commercial-grade part. For automotive use, Diodes offers the AEC-Q101 qualified BAV20WQ-7-F variant, which undergoes additional stress testing, PPAP documentation, and is manufactured in IATF 16949 certified facilities.
How does the SOD-123 package affect PCB layout?
The SOD-123 footprint requires precise pad dimensions (X = 0.90 mm, Y = 0.95 mm, X1 = 4.05 mm) and 7° chamfered edges per Diodes' outline drawing. Its small size allows dense placement but demands controlled reflow profiles to prevent tombstoning due to asymmetric thermal mass.
What is the reverse leakage current at elevated temperature?
At rated DC blocking voltage (150 V) and TJ = +100 °C, the peak reverse current (IRM) is specified at ≤15 µA. This value reflects worst-case leakage under thermal stress and is critical for low-power standby circuits where quiescent current must remain below 100 µA.
