Product details
Overview
BAV116WQ-7-F from Diodes Incorporated is an AEC-Q101 qualified surface-mount low-leakage switching diode in SOD-123 package, rated for 130 V peak reverse voltage, 215 mA forward current, and 5 nA leakage at 75 V/25°C. It delivers fast 3.0 µs reverse recovery time and 2.4 pF junction capacitance, enabling precision signal clamping and voltage protection in automotive sensor interfaces.
For engineers reviewing the BAV116WQ-7-F datasheet, BAV116WQ-7-F pinout, BAV116WQ-7-F application, or BAV116WQ-7-F equivalent, key selection criteria include leakage performance at elevated temperature, thermal resistance (500°C/W), automotive qualification status, and SOD-123 board-level reliability under vibration and thermal cycling.
Technical Context
This diode operates as a unidirectional voltage clamp and transient suppressor in low-power analog signal paths. Its 130 V VRRM supports 24 V automotive bus monitoring, while sub-100 nA leakage at 125°C ensures stable biasing in high-impedance sensor front-ends.
The device uses a planar epitaxial silicon structure with matte tin-plated alloy-42 leads, achieving 500°C/W junction-to-ambient thermal resistance on FR-4 PCBs using recommended pad layout. Its 3.0 µs tRR enables use in moderate-speed digital isolation and level-shifting circuits up to ~100 kHz.

Applications
| Automotive Cabin Sensors | Industrial Current Monitoring |
|---|---|
Use Scenario: Voltage clamping for thermistor-based cabin temperature sensing circuitry exposed to load-dump transients. IC Role / Device Role / Timing Role: Protection diode placed across sensor bridge output to limit common-mode overvoltage. Use Value: 130 V VRRM and <5 nA leakage preserve ADC input accuracy while surviving ISO 7637-2 pulse 5a. | Use Scenario: Bidirectional current sense amplifier input protection in 4–20 mA loop transmitters. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp preventing op-amp saturation during line fault events. Use Value: 2.4 pF CT avoids phase shift in >100 kHz current measurement bandwidths. |
| Body Control Module Inputs | Automotive LIN Bus Receivers |

IC Role / Device Role / Timing Role: Series blocking diode ensuring only valid logic-high signals reach MCU pins. Use Value: 215 mA IF rating handles worst-case pull-up current without thermal runaway. | Use Scenario: ESD and transient suppression on LIN physical layer receiver inputs (LIN 2.2A compliance). IC Role / Device Role / Timing Role: Low-leakage front-end clamp preserving bus idle voltage stability. Use Value: ≤80 nA leakage at 125°C prevents false wake-up in sleep-mode LIN receivers. |
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 |
|---|---|---|---|
| BAV199WQ-7-F | Higher VRRM (80 V vs. 130 V), higher leakage (50 nA @ 75 V/25°C) | Targeted at 12 V systems; less suitable for 24 V load-dump immunity | Select when cost sensitivity outweighs leakage and voltage margin requirements |
| BAS16WQ-7-F | Lower VRRM (100 V), faster tRR (2.5 µs), same SOD-123 package | Limited to 12 V/24 V hybrid systems where 30 V margin is acceptable | Choose for higher-speed digital clamping where 130 V rating is unnecessary |
Compared with BAV199WQ-7-F and BAS16WQ-7-F, the BAV116WQ-7-F provides superior voltage margin and leakage performance for 24 V automotive applications, making it optimal for under-hood sensors and LIN receivers requiring long-term bias stability.

FAQ
What is the maximum operating temperature for BAV116WQ-7-F?
The BAV116WQ-7-F is rated for junction temperatures from –55°C to +150°C, fully compliant with AEC-Q101 temperature cycling and high-temperature operating life requirements. Its 150°C upper limit supports under-hood placement in modern automotive ECUs without derating at ambient temperatures up to 125°C.
Is BAV116WQ-7-F suitable for bidirectional ESD protection?
No - the BAV116WQ-7-F is a unidirectional silicon switching diode optimized for low-leakage clamping in one polarity. For bidirectional ESD protection, Diodes Incorporated offers dedicated TVS arrays like the D24Z3.3LQ-7-F, which provide symmetrical ±3.3 V clamping with sub-nanosecond response.
Does BAV116WQ-7-F have a specified reverse recovery charge (Qrr)?
No - the official datasheet DS42774 Rev. 2–2 specifies only reverse recovery time (tRR = 3.0 µs) under defined test conditions (IF = IR = 10 mA, IRR = 0.1 × IR, RL = 100 Ω). Qrr is not characterized or guaranteed for this part and must be estimated from tRR and diode physics if required for snubber design.
Can BAV116WQ-7-F replace BAT54 series diodes in existing designs?
Not directly - while both are SOD-123 Schottky-like diodes, the BAV116WQ-7-F is a low-leakage PN junction diode (VF ≈ 1.0 V @ 10 mA, IR ≈ 5 nA), whereas BAT54 variants are Schottky diodes (VF ≈ 0.3 V, IR ≈ 1 µA). Substitution would increase forward drop and reduce leakage but degrade switching speed and thermal stability.
