Product details
Overview
BAV170T-7-F from Diodes Incorporated is a dual low-leakage switching diode in SOT-523 package, configured as two independent anode-common diodes with 85 V peak reverse voltage, 215 mA forward current per diode, and 5.0 nA leakage at 75 V. It serves in precision signal clamping and high-impedance bias networks in automotive sensor interfaces.
For engineers reviewing the BAV170T-7-F datasheet, BAV170T-7-F pinout, BAV170T-7-F application, or BAV170T-7-F equivalent, key selection criteria include ultra-low IR (5.0 nA @ 75 V), fast trr (3.0 μs), SOT-523 footprint compatibility, AEC-Q101 qualification, and dual-anode-common topology for rail-to-rail clamping.
Technical Context
This dual-diode device integrates two identical silicon epitaxial planar junction diodes sharing a common anode terminal, enabling bidirectional clamping or dual-path signal routing without cross-coupling. Its 833 °C/W thermal resistance and 150 mW power dissipation are defined under FR-4 board conditions with recommended pad layout.
The diode exhibits 0.90–1.25 V forward voltage across 1–150 mA, with reverse recovery time measured at IF = IR = 10 mA, Irr = 1 mA, RL = 100 Ω. Total capacitance remains stable at 2 pF (VR = 0, f = 1 MHz), supporting high-frequency signal integrity.

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 |
|---|---|---|---|
| BAV199T-7-F | Same SOT-523 package, but cathode-common configuration; VF slightly higher (1.25 V @ 150 mA) | Requires circuit redesign for cathode-referenced clamping; less suitable for anode-tied bias networks | Select when existing layout uses cathode-common topology or requires tighter VF matching with legacy BAV199 designs |
| BAS116T-7-F | Single diode, same leakage (5.0 nA) and VRRM (85 V), but no dual functionality; smaller die area | Needs two devices for dual-path operation, increasing board area and assembly cost | Choose only if single-diode function suffices and space permits duplication |
Compared with BAV199T-7-F, BAV170T-7-F enables anode-referenced clamping without trace rework; versus BAS116T-7-F, it delivers dual functionality in one footprint-critical for miniaturized sensor nodes where board area and BOM count directly impact certification cost and time-to-market.

FAQ
What is the pin configuration of BAV170T-7-F?
BAV170T-7-F uses a 4-pin SOT-523 package with pins arranged as follows: Pin 1 and Pin 2 are the common anodes; Pin 3 is Cathode A; Pin 4 is Cathode B. This anode-common dual-diode topology is confirmed in Diodes Inc. DS30258 Rev. 12–2, page 1 top-view diagram and marking table.
Is BAV170T-7-F suitable for automotive applications?
Yes - BAV170T-7-F is explicitly qualified to AEC-Q101 standards, operates from −65 °C to +150 °C, and uses green (halogen-free) molding compound. Its 5.0 nA leakage and 85 V VRRM meet requirements for engine control unit sensor interfaces and ADAS front-end protection per ISO 16750-2.
How does BAV170T-7-F differ from BAV199T-7-F?
BAV170T-7-F has an anode-common configuration (Pins 1&2 = anodes), while BAV199T-7-F is cathode-common (Pin 3 = common cathode). Both share SOT-523 packaging and 85 V VRRM, but their internal connectivity mandates different PCB layouts and biasing schemes for clamping applications.
What is the thermal derating behavior of BAV170T-7-F?
BAV170T-7-F dissipates 150 mW at TA = 25 °C, with linear derating above 25 °C at 0.18 mW/°C (150 mW ÷ 833 °C/W), reaching zero dissipation at ~108 °C ambient. This curve is plotted in Figure 1 of DS30258 and assumes mounting on FR-4 with Diodes' AP02001-recommended pad layout.
