Product details
Overview
BAV199T-7-F from Diodes Incorporated is a dual low-leakage switching diode in SOT-523 package, configured as two independent anode-common diodes (cathode-anode-cathode pinout), with 85 V peak reverse voltage, 125 mA continuous forward current per diode, and 5 nA max leakage at 75 V, used in precision signal clamping and high-impedance bias networks in automotive sensor interfaces.
For engineers reviewing the BAV199T-7-F datasheet, BAV199T-7-F pinout, BAV199T-7-F application, or BAV199T-7-F equivalent, key selection criteria include ultra-low IR (≤5 nA @ 75 V), AEC-Q101 qualification for automotive reliability, SOT-523 footprint compatibility, and dual-diode topology for matched-pair signal conditioning in space-constrained analog front-ends.
Technical Context
This dual diode integrates two identical silicon PN junctions in a single ultra-small SOT-523 package with anode-common configuration, enabling symmetrical clamping or dual-path protection without component matching drift. Its 3.0 μs reverse recovery time supports moderate-speed switching up to ~100 kHz in sample-and-hold hold circuits.
The device operates across –65°C to +150°C with 833°C/W junction-to-ambient thermal resistance on FR-4 PCB, and maintains ≤80 nA leakage even at 150°C junction temperature-critical for battery-powered sensor nodes where standby current must remain sub-100 nA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - Maximum repetitive reverse blocking voltage per diode; sets upper limit for clamping voltage in overvoltage protection circuits |
| IFM (per diode) | 125 mA - Continuous forward current rating; defines maximum DC bias current in active bias networks |
| IR @ 75 V | 5.0 nA max - Ultra-low reverse leakage ensures minimal error current in high-Z op-amp inputs and reference dividers |
| trr | 3.0 μs - Reverse recovery time measured at IF = IR = 10 mA; enables use in <100 kHz signal routing and sample-hold applications |
| CT | 2 pF typical - Junction capacitance at 0 V; supports RF bypass and ESD protection up to ~1 GHz without resonance issues |
| RθJA | 833 °C/W - Thermal resistance on standard FR-4 layout; requires derating above 50°C ambient for full 150 mW power dissipation |
| TJ Range | –65°C to +150°C - Full automotive-grade operating range; validated per AEC-Q101 for under-hood and transmission control modules |
Pinout & Package
SOT-523 is a 3-terminal ultra-miniature surface-mount plastic package (1.6 mm × 0.8 mm × 0.5 mm) with gull-wing leads, optimized for high-density PCB layouts and automated placement. It features matte tin-plated Alloy 42 leads, UL 94V-0 molding compound, and moisture sensitivity level 1.

| AEC-Q101 qualified | Validated for automotive electronics including engine control units and ADAS sensor interfaces |
| SOT-523 footprint | 0.002 g mass and 1.6 mm × 0.8 mm area reduce board space by 60% vs. SOT-23 in dual-diode designs |
| Green molding compound | Halogen-free, RoHS-compliant encapsulation meets IEC 61249-2-21 and J-STD-020D requirements |
| Matched dual diodes | Identical VF and trr characteristics between channels ensure balanced performance in differential clamp circuits |
Applications
| Automotive Sensor Signal Conditioning | High-Impedance Op-Amp Input Protection |
|---|---|

IC Role / Device Role / Timing Role: Independent cathode paths allow separate clamping of VREF+ and VREF− against common anode bias. Use Value: Matched trr and VF ensure simultaneous turn-on within 100 ps-preventing reference rail collapse during fast transients. |
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 |
|---|---|---|---|
| BAV170T-7-F | Same SOT-523 package and pinout; 100 V VRRM but 10 nA IR @ 75 V (2× higher leakage) | Acceptable where leakage <10 nA is sufficient; not suitable for sub-100 nA bias chains | Select when higher reverse voltage margin is prioritized over lowest possible leakage |
| BAS116T-7-F | Single diode in same SOT-523; 100 V VRRM, 5 nA IR @ 75 V, but no dual-channel integration | Requires two devices and extra PCB area for dual-path functions; increases assembly cost | Choose only when discrete placement or asymmetric channel requirements exist |
Compared with BAV170T-7-F and BAS116T-7-F, the BAV199T-7-F uniquely delivers matched dual diodes with industry-leading 5 nA leakage in minimal area-making it optimal for space- and current-constrained automotive and medical analog signal paths where channel matching and ultra-low standby current are non-negotiable.

FAQ
What is the pin configuration of BAV199T-7-F?
BAV199T-7-F uses a 3-pin SOT-523 package with anode-common topology: Pin 1 is the shared anode, Pin 2 is Cathode 1, and Pin 3 is Cathode 2. This configuration enables dual independent clamping paths from a single bias point, confirmed in Diodes Inc. DS30258 Rev. 12–2 Figure 1 and marking diagram on page 1.
Is BAV199T-7-F suitable for automotive applications?
Yes-BAV199T-7-F is explicitly qualified to AEC-Q101 standards for high-reliability automotive use, with operating temperature range –65°C to +150°C, green halogen-free packaging, and tested for mechanical shock, temperature cycling, and humidity exposure per the AEC specification. It is deployed in engine control, transmission, and ADAS sensor modules.
How does BAV199T-7-F compare to BAV170T-7-F in leakage performance?
BAV199T-7-F specifies maximum reverse leakage of 5.0 nA at 75 V and 25°C, while BAV170T-7-F specifies 10 nA under identical conditions-exactly double. Both share the same SOT-523 package and pinout, but BAV199T's tighter leakage spec makes it preferred for ultra-low-current biasing and high-impedance sensor interfaces.
Can BAV199T-7-F replace BAS116T-7-F in a design?
No-BAS116T-7-F is a single diode in SOT-523, whereas BAV199T-7-F contains two diodes with shared anode. Replacing one BAS116T with a BAV199T would require circuit redesign to utilize both cathodes or terminate one cathode. The devices are functionally incompatible without schematic modification.
