Product details
Overview
BAS116-7-F from Diodes Incorporated is a surface-mount low-leakage silicon switching diode in SOT23 package, rated for 85 V peak repetitive reverse voltage, 215 mA forward continuous current, and exhibiting only 5.0 nA leakage at 75 V and 25°C. It serves as a precision signal-level clamp or high-impedance biasing element in analog front-ends and sensor interface circuits.
For engineers reviewing the BAS116-7-F datasheet, BAS116-7-F pinout, BAS116-7-F application, or BAS116-7-F equivalent, key selection criteria include ultra-low IR (5 nA @ 75 V), fast trr (3.0 µs), low CT (2 pF), and AEC-Q101 qualification for automotive-grade reliability in space-constrained designs.
Technical Context
The BAS116-7-F is a planar epitaxial silicon PN junction diode optimized for low-leakage operation across temperature. Its design emphasizes minimal capacitance (2 pF at 0 V) and rapid recovery (trr ≤ 3.0 µs under IF = IR = 10 mA), enabling use in high-frequency sampling hold and precision DC restoration.
Thermal performance is defined by RθJA = 500°C/W on FR-4 with 1-inch² 2 oz copper, supporting operation from –55°C to +150°C. The device uses matte tin-plated Alloy 42 leadframe and meets J-STD-020 Level 1 moisture sensitivity.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4148W-7-F | Higher IR (25 nA @ 20 V), higher CT (4 pF), same SOT23 package | General-purpose switching; not specified for <10 nA leakage-critical paths | Select only when leakage <10 nA is not required and cost is primary constraint |
| BAS216-7-F | Lower VRRM (100 V), identical IR (5 nA), same trr and CT | Same low-leakage performance but rated for higher reverse stress in 48 V systems | Prefer for new designs targeting 75–100 V blocking where margin matters |
Compared with 1N4148W-7-F and BAS216-7-F, the BAS116-7-F uniquely balances 85 V rating, 5 nA leakage, and 2 pF capacitance-making it optimal for precision analog interfaces where all three parameters constrain system accuracy.

FAQ
What is the maximum operating temperature for BAS116-7-F?
The BAS116-7-F is rated for junction and storage temperatures from –55°C to +150°C. Its thermal resistance is 500°C/W on standard FR-4 PCB with 1-inch² 2 oz copper pad, allowing full-rated current derating above +25°C ambient per Figure 2 in the datasheet.
Is BAS116-7-F suitable for automotive applications?
The BAS116-7-F is not AEC-Q101 qualified; however, its automotive-grade counterpart BAS116Q-7-F is fully qualified, PPAP-capable, and manufactured in IATF16949-certified facilities. For production automotive use, BAS116Q-7-F must be selected.
How does BAS116-7-F differ from standard 1N4148 variants?
BAS116-7-F delivers 5 nA leakage at 75 V versus ≥25 nA for 1N4148W-7-F, and 2 pF capacitance versus ~4 pF. These differences make it suitable for high-impedance analog circuits where leakage-induced offset and capacitive loading degrade performance.
What is the reverse recovery time test condition for BAS116-7-F?
The specified trr of 3.0 µs is measured under IF = IR = 10 mA, Irr = 0.1 × IR, and RL = 100 Ω, per JEDEC-standard conditions. This reflects real-world behavior in active-clamp and signal-sampling circuits with moderate load impedances.
