Product details
Overview
BAV116HWF-7 from Diodes Incorporated is an ultra-low-leakage surface-mount switching diode in SOD123F package, rated for 85 V peak reverse voltage, 5 nA leakage at 75 V, and 3 µs reverse recovery time. It serves as a precision blocking or signal clamping device in battery-sensitive portable electronics where minimal standby current drain is critical.
For engineers reviewing the BAV116HWF-7 datasheet, BAV116HWF-7 pinout, BAV116HWF-7 application, or BAV116HWF-7 equivalent, key selection criteria include verified leakage performance at elevated temperature, thermal resistance to solder point (70 °C/W), AEC-Q101 qualification status, and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This diode employs a planar epitaxial silicon structure optimized for low IR and fast trr trade-off. Its flat leadframe design reduces thermal resistance to solder point (RθJSP = 70 °C/W) and improves power derating above 25 °C ambient.
It operates across –65 °C to +150 °C, with leakage rising to 80 nA at VR = 75 V and TJ = +150 °C, and maintains stable VF ≤ 1.25 V up to IF = 150 mA - enabling reliable operation in automotive cabin modules and industrial sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Peak Reverse Voltage) | 85 V - supports blocking in 48 V automotive subsystems and 24 V industrial rails without breakdown risk |
| IR (Leakage Current) | 5 nA @ VR = 75 V, TA = 25 °C - ensures <1 µA total standby drain in multi-diode bias networks |
| trr (Reverse Recovery Time) | 3 µs - enables use in moderate-speed switching (<500 kHz) signal routing and sample-hold protection |
| CT (Total Capacitance) | 2 pF @ VR = 0 V, f = 1 MHz - minimizes signal distortion in RF detector and antenna switch bias paths |
| RθJSP (Junction-to-Solder Point) | 70 °C/W - allows direct thermal coupling to copper pour for sustained 215 mA DC operation on FR-4 |
| AEC-Q101 Qualified | Yes - validated for automotive applications including body control modules and infotainment power sequencing |
Pinout & Package
Package: SOD123F - molded plastic case with flat leadframe, UL 94V-0 rating, moisture sensitivity level 1, cathode indicated by bar marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry terminal | Connected to lower-potential node in blocking configuration; requires ≥0.35 mm lead length for thermal relief |
| Cathode (bar-marked) | Forward current exit / reverse blocking terminal | Must be routed to higher-potential rail; matte tin finish ensures MIL-STD-202-compliant solderability |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low leakage current | 5 nA @ 75 V enables >10-year battery life in always-on IoT sensors with single-cell Li-ion supply |
| Flat leadframe thermal design | RθJSP = 70 °C/W supports 375 mW dissipation without external heatsink on standard 2-layer PCB |
| Low capacitance (2 pF) | Preserves rise/fall integrity in 10–100 MHz RF envelope detection and antenna diversity switching |
| AEC-Q101 qualification | Validated for automotive underhood and cabin environments per stress test requirements (HTOL, TCT, ESD) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-leakage switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV199LT1G | Higher IR = 100 nA @ 75 V; same SOD-323 package; trr = 4 ns (faster but leakier) | Better for high-frequency signal steering; unsuitable for multi-year battery retention | Select only when speed dominates leakage budget, e.g., RF switch driver biasing |
| 1N4148WS | IR = 25 nA @ 75 V; SOD-323; trr = 4 ns; not AEC-Q101 qualified | General-purpose replacement; lacks automotive qualification and thermal performance | Acceptable for consumer wearables but not for automotive or medical-grade designs |
Compared with BAV199LT1G and 1N4148WS, the BAV116HWF-7 uniquely balances sub-10 nA leakage, 3 µs trr, and AEC-Q101 qualification - making it the only choice for automotive cabin sensors requiring both long-term stability and moderate switching speed.

FAQ
What is the maximum junction temperature for continuous operation?
The BAV116HWF-7 has an operating junction temperature range of –65 °C to +150 °C. Continuous operation at +150 °C is permitted provided power dissipation remains within the derated limit - e.g., ≤125 mW at +100 °C ambient per the published derating curve.
Is the SOD123F package compatible with standard reflow profiles?
Yes - the SOD123F package is qualified for lead-free reflow per JEDEC J-STD-020, with moisture sensitivity level 1. Standard Pb-free peak profile (260 °C, 30 sec max) achieves full wetting without delamination or voiding when using recommended pad layout AP02001.
How does leakage current change at elevated temperature?
At VR = 75 V, leakage rises from 5 nA at +25 °C to 80 nA at +150 °C junction temperature. This 16× increase is fully characterized and reflected in the datasheet's Figure 3, supporting accurate worst-case power budgeting in thermally constrained designs.
Can BAV116HWF-7 replace BAV21 in legacy designs?
No - BAV21 is a through-hole DO-35 device with higher IR (100 nA) and slower trr (50 ns). While electrically similar in basic function, BAV116HWF-7's SOD123F footprint, AEC-Q101 qualification, and 5 nA leakage make it incompatible as a drop-in replacement without PCB redesign and thermal validation.
