Product details
Overview
BAV16W-7 from Diodes Incorporated is a surface-mount fast-switching silicon switching diode in SOD123 package, rated for 100 V peak repetitive reverse voltage, 300 mA forward current, and 4 ns reverse recovery time. It delivers low forward voltage (0.715 V at 1 mA) and low junction capacitance (2 pF), making it suitable for high-speed signal routing and clamping in digital logic interfaces and power supply flyback protection.
For engineers reviewing the BAV16W-7 datasheet, BAV16W-7 pinout, BAV16W-7 application, or BAV16W-7 equivalent, key selection criteria include reverse recovery speed, forward voltage drop at low currents, junction capacitance under zero bias, thermal resistance (315 °C/W), and RoHS-compliant green packaging with matte tin terminals.
Technical Context
The BAV16W-7 operates as a unidirectional PN-junction switching diode optimized for high-frequency transient suppression and signal-level rectification. Its 4 ns reverse recovery time enables reliable operation in 10–50 MHz clocked circuits, while its 2 pF junction capacitance minimizes signal distortion in high-impedance node clamping.
Thermally, it sustains operation from –55 °C to +150 °C with 400 mW power dissipation on FR-4 PCBs using standard 2" × 2" copper pads. The cathode band polarity marking and SOD123 mechanical outline ensure compatibility with automated pick-and-place systems and reflow profiles compliant with J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports DC blocking in 48 V industrial control rails and 3.3/5 V logic-level signal isolation without breakdown |
| tRR | 4 ns - enables clean edge transitions in >25 MHz digital signal conditioning and pulse shaping circuits |
| VF @ 1 mA | 0.715 V max - reduces voltage loss in low-current bias networks and precision reference clamping |
| CT @ 0 V | 2.0 pF max - preserves signal integrity in RF detector inputs and high-Z analog switch nodes |
| RθJA | 315 °C/W - requires minimal copper area for thermal management in space-constrained PCB layouts |
| IFM | 300 mA - handles transient surge currents in I/O line protection and small-signal power path switching |
Pinout & Package
Package: SOD123 - surface-mount plastic case with cathode band marking, 1.55 mm nominal width, 2.65 mm length, and 0.30 mm lead thickness; compatible with IPC-7351B SOIC-123 footprint and J-STD-020 Level 1 moisture handling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; accepts up to 300 mA continuous forward current |
| Cathode (marked) | Forward current exit / reverse blocking terminal | Band identifies polarity; withstands 100 V reverse bias and conducts only when anode > cathode by ≥0.7 V |
Key Features
| Feature | Design Value |
|---|---|
| Fast reverse recovery | 4 ns - enables use in 25+ MHz clock distribution networks without pulse skew or ringing |
| Low forward voltage | 0.715 V @ 1 mA - minimizes loading error in precision voltage reference clamp circuits |

| Green RoHS compliance | Halogen- and antimony-free molding compound (<900 ppm Br/Cl, <1000 ppm Sb) - meets automotive and medical regulatory requirements |
Applications
| Digital Logic Clamping | Power Supply Flyback Protection |
|---|---|
Use Scenario: Protecting CMOS input pins from ESD-induced overvoltage during hot-plug events in USB or UART interfaces. IC Role / Device Role / Timing Role: Fast-clamp diode shunting transients to ground or rail before logic gate damage occurs. Use Value: 4 ns tRR ensures clamping activation within one 100 MHz clock cycle, preventing metastability in synchronous receivers. | Use Scenario: Suppressing voltage spikes across MOSFET drains in buck converter secondary-side snubbers. IC Role / Device Role / Timing Role: Freewheeling diode conducting flyback current during switch-off phase. Use Value: Low VF (0.715 V) reduces conduction loss at light loads; 100 V VRRM accommodates 48 V system derating margins. |
| RF Signal Detection | High-Speed Data Line Protection |
Use Scenario: Demodulating AM signals in low-power IoT sensor front-ends operating at 433 MHz or 2.4 GHz ISM bands. IC Role / Device Role / Timing Role: Envelope detector diode converting RF carrier amplitude to baseband voltage. Use Value: 2 pF CT avoids resonant detuning of matching networks; low leakage (<1 µA @ 75 V) preserves detector sensitivity. | Use Scenario: Guarding LVDS or RS-422 differential pairs against cable discharge events in industrial fieldbus nodes. IC Role / Device Role / Timing Role: Bidirectional transient suppressor placed between data lines and ground/rails. Use Value: Cathode-anode symmetry allows dual-diode configuration; 315 °C/W RθJA supports sustained 100 mA surge without thermal runaway. |
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 | Identical electrical specs (VRRM=100 V, tRR=4 ns, VF=0.715 V @ 1 mA); same SOD123 package and green RoHS construction | No functional difference; used interchangeably in non-automotive designs | Select when sourcing flexibility is prioritized over part number consistency |
| BAS16W-7-F | Slightly higher VF (0.855 V @ 10 mA); otherwise matches VRRM, tRR, CT, and package | Marginally reduced efficiency in low-current bias networks; identical performance in clamping and flyback roles | Prefer for cost-sensitive consumer applications where 0.14 V higher drop is acceptable |
Compared with 1N4148W-7-F and BAS16W-7-F, the BAV16W-7 offers identical switching performance and thermal behavior but is distinguished by Diodes Inc.'s specific process qualification and traceable lot control-critical for industrial BOM continuity and long-lifecycle programs.

FAQ
Is BAV16W-7 pin-compatible with 1N4148W-7-F?
Yes - both use the SOD123 package with identical anode/cathode terminal layout, cathode band marking, and mechanical dimensions. No PCB redesign is needed when substituting between these parts in existing layouts.
What is the maximum operating temperature for continuous use?
The BAV16W-7 is rated for continuous operation from –55 °C to +150 °C junction temperature. At ambient temperatures above 70 °C, derating per Figure 1 applies: power dissipation must be reduced linearly to 0 mW at 150 °C ambient on standard FR-4 board.
Does BAV16W-7 meet AEC-Q101 for automotive use?
No - the BAV16W-7 is not AEC-Q101 qualified. For automotive applications, Diodes specifies the 1N4148WQ-7-F variant, which undergoes additional stress testing, PPAP documentation, and is manufactured in IATF 16949-certified facilities.
Can BAV16W-7 replace BAT54 series Schottky diodes?
No - the BAV16W-7 is a silicon PN diode with 0.715 V VF and 4 ns tRR, whereas BAT54 devices are Schottky diodes with ~0.3 V VF and sub-nanosecond switching. Substitution would increase forward loss and slow switching in low-voltage, high-frequency circuits.
