Product details
Overview
BAS116Q-7-F from Diodes Incorporated is an AEC-Q101 qualified surface-mount low-leakage switching diode in SOT23 package, featuring 85 V peak repetitive reverse voltage, ≤80 nA leakage at 75 V and 150 °C, and 3.0 µs reverse recovery time. It serves as a precision signal clamping or high-impedance biasing diode in automotive sensor interfaces and analog front-end protection circuits.
For engineers reviewing the BAS116Q-7-F datasheet, BAS116Q-7-F pinout, BAS116Q-7-F application, or BAS116Q-7-F equivalent, key selection criteria include ultra-low IR at elevated temperature, fast trr for moderate-speed signal routing, SOT23 footprint compatibility, and IATF16949-manufactured traceability for automotive-grade BOMs.
Technical Context
The BAS116Q-7-F is a planar epitaxial silicon switching diode optimized for low-leakage operation across -55 °C to +150 °C. Its junction design minimizes generation-recombination current, enabling stable <5 nA IR at VR = 75 V and TA = 25 °C, and <80 nA at TJ = 150 °C.
It exhibits a typical total capacitance of 2 pF at 0 V and 1 MHz, supporting high-frequency signal path integrity. The 3.0 µs reverse recovery time (IF = IR = 10 mA, Irr = 0.1 × IR) confirms suitability for <1 MHz digital signal conditioning and analog sampling hold applications.
Key Specifications

|---|---|
| VRRM | 85 V - supports DC blocking in 24 V automotive systems with ≥3× safety margin |
| IR @ 75 V, 25 °C | ≤5.0 nA - enables high-impedance bias networks without signal drift |
| IR @ 75 V, 150 °C | ≤80 nA - maintains accuracy in under-hood sensor signal chains |
| trr | 3.0 µs - suitable for 300 kHz–1 MHz pulse shaping and sample-and-hold timing |
| VF @ 10 mA | 1.0 V max - ensures low forward drop in low-power biasing paths |
| CT @ 0 V, 1 MHz | 2 pF - minimizes capacitive loading on high-Z op-amp inputs or RF detector nodes |

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 |
|---|---|---|---|
| ON Semiconductor NSS1C200LT1G | Higher VF (1.25 V @ 10 mA), lower VRRM (70 V), same SOT23 package | Less suitable for 24 V system clamping; acceptable only where VR ≤ 60 V | Select when cost sensitivity outweighs leakage and voltage margin requirements |
| Vishay VS-2EDH02HM3/85A | Higher IR (500 nA @ 75 V, 25 °C), TO-236AB package, non-AEC-Q101 | Lacks automotive qualification and thermal performance for under-hood use | Acceptable for industrial control boards with relaxed reliability and leakage specs |
Compared with NSS1C200LT1G and VS-2EDH02HM3/85A, the BAS116Q-7-F uniquely combines AEC-Q101 compliance, <5 nA IR at room temperature, and 85 V blocking-making it the only option qualified for precision automotive sensor biasing where leakage-induced offset must remain below 1 µV in 10 MΩ networks.

FAQ
What is the maximum junction temperature rating for BAS116Q-7-F?
The BAS116Q-7-F has an operating junction temperature range of -55 °C to +150 °C, verified per AEC-Q101 stress testing. Its thermal resistance junction-to-ambient is 500 °C/W on a standard FR-4 board with 2 oz copper, allowing 250 mW power dissipation at 25 °C ambient before derating begins.
Is BAS116Q-7-F pin-compatible with BAS16 or 1N4148 in SOT23?
Yes-BAS116Q-7-F uses the standard SOT23-3 outline with identical pin 1 (anode), pin 2 (cathode), and pin 3 (NC) assignment as BAS16 and 1N4148 SOT23 variants. However, its leakage and high-temperature performance exceed both, making it a functional upgrade-not just a footprint match.
Does BAS116Q-7-F require special PCB layout considerations?
While no special layout is required, best practice is to minimize trace length between cathode and ground plane to reduce parasitic inductance during transient suppression, and avoid thermal vias under pin 3 since it is not electrically connected. The recommended pad layout matches Diodes' SOT23 outline with 0.9 mm solder mask opening and 1.35 mm × 0.9 mm copper pads.
How does the AEC-Q101 qualification impact supply chain use of BAS116Q-7-F?
AEC-Q101 qualification means BAS116Q-7-F undergoes accelerated stress testing-including temperature cycling, HTRB, and ESD-to validate reliability for automotive electronics. This enables direct inclusion in PPAP submissions and eliminates need for customer requalification, shortening time-to-market for Tier-1 and OEM programs.
