Product details
Overview
BAV199-7-F from Diodes Incorporated is a dual surface-mount low-leakage switching diode in SOT23 package, featuring 85 V peak reverse voltage, ≤5 nA leakage at 75 V, 3.0 µs reverse recovery time, and 140 mA double-diode forward current. It serves as a high-speed signal clamping and polarity protection device in USB interface circuits and low-power sensor front-ends.
For engineers reviewing the BAV199-7-F datasheet, BAV199-7-F pinout, BAV199-7-F application, or BAV199-7-F equivalent, key selection criteria include ultra-low IR at elevated temperature, fast trr for signal integrity preservation, dual-diode integration for space-constrained ESD protection, and SOT23 compatibility with automated PCB assembly.
Technical Context
The BAV199-7-F integrates two independent silicon planar epitaxial diodes in a single SOT23-3 package with common cathode configuration (Pin 1: Anode A, Pin 2: Cathode, Pin 3: Anode B). Its low 5 nA IR at VR = 75 V enables precision biasing in high-impedance analog nodes.
With 3.0 µs trr under IF = IR = 10 mA, RL = 100 Ω conditions and 2 pF total capacitance at VR = 0 V, it supports >10 MHz signal routing while maintaining minimal loading on RF-sensitive inputs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - supports DC blocking in 24 V industrial I/O and 48 V PoE-powered interfaces without breakdown |
| IR @ 75 V | ≤5 nA - preserves accuracy in µA-level sensor bias networks and battery-monitoring dividers |
| trr | 3.0 µs - enables clean edge transitions in 1–5 MHz digital signal conditioning paths |
| CT @ 0 V | 2 pF - minimizes capacitive loading on 50 Ω RF traces and high-Z op-amp inputs |
| IFM (dual) | 140 mA - sustains continuous operation in dual-path LED indicator or logic-level translation circuits |
| RθJA | 500 °C/W - requires thermal-aware pad layout per Diodes' SOT23 footprint to maintain TJ < 125 °C at full load |
Pinout & Package
SOT23-3 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm), UL 94V-0 rated, matte tin-plated alloy 42 leadframe, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode A | Accepts positive input for clamping or steering; routed to signal source in ESD protection path |
| Pin 2 | Common Cathode | Shared output node; connects to system ground or reference rail for bidirectional clamp operation |
| Pin 3 | Anode of Diode B | Independent anode for second signal path; enables dual-rail protection or polarity-selective rectification |
Key Features
| Feature | Design Value |
|---|---|
| Dual-diode integration in SOT23 | Reduces board area by 40% vs. discrete SOD-323 diodes; eliminates placement misalignment risk in differential protection |
| ≤5 nA leakage at 75 V | Enables stable DC bias in 10 MΩ+ feedback networks used in precision instrumentation amplifiers |
| 3.0 µs reverse recovery | Prevents pulse distortion in 1–3 MHz clock distribution and data strobe lines |
| AEC-Q101 qualified variant available (BAV199Q) | Supports automotive body control modules requiring PPAP documentation and IATF16949 traceability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD7000LT1G | Higher IR (100 nA @ 25 V); 4 ns trr; same SOT23-3 pinout | Better for <10 MHz digital switching; less suitable for µA-level analog biasing | Select when speed outweighs leakage sensitivity |
| BAV99W-7-F | Same IR spec (5 nA), but 4.0 µs trr; common-anode topology (Pin 1: Cathode A, Pin 2: Anode, Pin 3: Cathode B) | Requires PCB layout revision; better for cathode-referenced clamping topologies | Choose only if existing design uses common-anode architecture |
Compared with MMBD7000LT1G and BAV99W-7-F, the BAV199-7-F uniquely balances sub-5 nA leakage at 75 V with 3.0 µs trr in a common-cathode SOT23-3, making it optimal for mixed-signal protection where both precision DC stability and moderate-speed transient response are required.

FAQ
What is the pin configuration of BAV199-7-F?
The BAV199-7-F uses a common-cathode SOT23-3 arrangement: Pin 1 is Anode A, Pin 2 is the shared Cathode, and Pin 3 is Anode B. This configuration enables dual-rail clamping to a single reference rail and is confirmed in Diodes' DS30232 Rev. 11 schematic and top-view marking diagram.
Is BAV199-7-F suitable for automotive applications?
The BAV199-7-F is not AEC-Q101 qualified; however, its automotive-grade variant BAV199Q-7-F is fully qualified, PPAP-capable, and manufactured in IATF16949-certified facilities. For non-safety-critical cabin electronics with relaxed qualification requirements, BAV199-7-F may be used subject to internal validation.
How does temperature affect leakage current in BAV199-7-F?
At TJ = +150°C and VR = 75 V, leakage rises to ≤80 nA-16× higher than the 5 nA maximum at +25°C. This is documented in DS30232 Table "Electrical Characteristics" and validated in Fig. 3's reverse current curves, confirming predictable thermal drift for thermal margining.
Can BAV199-7-F replace BAV99 in existing designs?
BAV199-7-F and BAV99 share SOT23-3 packaging and common-cathode topology but differ in trr (3.0 µs vs. 4.0 µs) and IR (5 nA vs. 100 nA). Direct replacement is viable in low-leakage applications; verify timing margins in >2 MHz signal paths and confirm layout compatibility with Diodes' recommended pad dimensions.
