Product details
Overview
BAV116HWFQ-7 from Diodes Incorporated is an AEC-Q101-qualified surface-mount switching diode in SOD123F package, featuring 85 V peak reverse voltage, 5 nA leakage current at 75 V, 3 µs reverse recovery time, and 215 mA forward current. It serves as a low-leakage signal rectifier in automotive sensor interfaces and portable power management circuits.
For engineers reviewing the BAV116HWFQ-7 datasheet, BAV116HWFQ-7 pinout, BAV116HWFQ-7 application, or BAV116HWFQ-7 equivalent, key selection criteria include ultra-low IR at high VR, thermal performance under automotive temperature cycling, RoHS/Green compliance, and SOD123F board-level reliability in space-constrained designs.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for minimal minority-carrier storage, enabling fast 3 µs trr with low 2 pF capacitance at 0 V. Its flat leadframe design reduces RθJSP to 70 °C/W, supporting stable operation up to +150 °C junction temperature.
The device meets AEC-Q101 stress test requirements including HTGB, HTRB, and TCT, with leakage current specified at ≤5 nA @ VR = 75 V (TA = +25°C) and ≤80 nA @ same VR at TJ = +150°C - critical for battery-sensitive automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VRRM | 85 V - supports 24 V automotive systems with ≥3.5× safety margin against load-dump transients |
| IR @ VR = 75 V | 5 nA - enables microamp-level standby current in always-on vehicle modules |
| trr | 3 µs - ensures clean switching in 100–500 kHz DC-DC feedback paths |
| IFM | 215 mA - sustains continuous current in ECU input protection and signal clamping |
| CT @ 0 V, 1 MHz | 2 pF - minimizes signal distortion in RF detector and antenna switch bias networks |
| RθJSP | 70 °C/W - allows direct thermal coupling to PCB copper for passive cooling in sealed enclosures |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV199W-7-F | Higher IR (100 nA @ VR = 75 V); same SOD-323 package; 100 V VRRM | Not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select only for cost-sensitive consumer portables where leakage >20× higher is acceptable |
| ESD5Z3.3T5G | TVS diode (3.3 V breakdown); 12 pF CT; not a switching diode | Designed for ESD suppression only; cannot replace BAV116HWFQ-7 in rectification roles | Use only as supplemental transient clamp - never as functional replacement |
Compared with BAV199W-7-F and ESD5Z3.3T5G, the BAV116HWFQ-7 uniquely delivers automotive-grade reliability, sub-10 nA leakage, and 3 µs trr in a thermally enhanced SOD123F package - making it irreplaceable in safety-critical, battery-sensitive, and high-temperature signal-path applications.

FAQ
What is the maximum operating temperature for BAV116HWFQ-7 in continuous use?
The BAV116HWFQ-7 has a specified junction temperature range of –65°C to +150°C. Under recommended PCB layout (per AP02001), its thermal resistance junction-to-solder-point is 70°C/W, allowing sustained operation at +150°C junction temperature when ambient and power dissipation conditions remain within derated limits shown in Figure 1.
Is BAV116HWFQ-7 compatible with lead-free reflow profiles?
Yes - the device uses matte tin-plated copper alloy terminals and is rated for standard IPC/JEDEC J-STD-020 Level 1 moisture sensitivity. It withstands peak reflow temperatures up to 260°C for 30 seconds and is fully compatible with SnAgCu (SAC305) solder processes without delamination or voiding.
How does the SOD123F package differ from standard SOD-123 in thermal performance?
The SOD123F features a flat leadframe design that reduces thermal resistance junction-to-solder-point (RθJSP) to 70°C/W - approximately 40% lower than typical SOD-123 packages (~120°C/W). This improvement results from increased copper cross-section and direct thermal path to PCB copper, verified per JEDEC standards.
Can BAV116HWFQ-7 be used as a replacement for BAV21 in automotive applications?
No - while both are 85 V switching diodes, BAV21 is not AEC-Q101 qualified, lacks halogen/antimony-free certification, and exhibits higher leakage (50 nA @ VR = 75 V). BAV116HWFQ-7's qualification, 10× lower IR, and thermal enhancements make it the only compliant option for automotive use cases.
