Product details
Overview
BAS116T-7-F from Diodes Incorporated is a surface-mount ultra-low-leakage silicon switching diode in SOT-523 package, rated for 85 V peak reverse voltage, 215 mA forward current, and 5 nA max leakage at 75 V, used in precision signal clamping and low-power analog front-ends.
For engineers reviewing the BAS116T-7-F datasheet, BAS116T-7-F pinout, BAS116T-7-F application, or BAS116T-7-F equivalent, key selection criteria include reverse leakage stability at high temperature, fast 3.0 μs reverse recovery time, low 0.90 V forward voltage at 1 mA, and AEC-Q101 qualification for automotive sensor interfaces.
Technical Context
This diode operates as a single-anode, single-cathode unidirectional switch with junction capacitance of 2 pF at 0 V, enabling high-frequency signal routing in RF detector and ESD protection circuits. Its thermal resistance of 833 °C/W reflects FR-4 board mounting per recommended pad layout.
The device delivers stable reverse characteristics up to +150 °C ambient, with leakage rising to only 80 nA at 75 V and Tj = 150 °C - critical for battery-powered instrumentation where standby current must remain sub-100 nA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - supports signal rail clamping in 24 V industrial control systems without breakdown |
| IF | 215 mA - sufficient for biasing low-current op-amp input stages or LED indicator drivers |
| IR @ 75 V | 5.0 nA max - enables precision DC coupling in µV-level sensor amplifiers |
| trr | 3.0 μs - allows use in 100 kHz–1 MHz envelope detection without waveform distortion |
| CT | 2 pF - minimizes loading on 50 Ω RF paths in AM/FM receiver front-ends |
| PD | 150 mW - defines maximum continuous dissipation on standard FR-4 PCB with defined pad layout |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS16W-7-F | Higher leakage (50 nA @ 75 V), same SOT-323 package, 100 V VRRM | Less suitable for µA-level bias networks but acceptable for general-purpose clamping | Select when higher reverse voltage margin is needed and leakage tolerance >10× higher |
| 1N4148W-7-F | Standard leakage (25 nA @ 20 V), SOD-123 package, 100 V VRRM, slower trr (4 ns) | Not AEC-Q101 qualified; larger footprint limits high-density layouts | Choose for cost-sensitive consumer designs where automotive qualification is unnecessary |
Compared with BAS116T-7-F, BAS16W-7-F trades 10× higher leakage for +15 V reverse margin, while 1N4148W-7-F sacrifices AEC-Q101 compliance and ultra-low leakage for broader availability and lower unit cost in non-automotive production.

FAQ
What is the maximum junction temperature for BAS116T-7-F?
The absolute maximum junction temperature is +150 °C, matching its storage temperature rating. Derating begins at +25 °C ambient, with linear reduction to zero power dissipation at +150 °C, per Figure 1 in DS30258 Rev. 12–2. This allows operation in under-hood automotive environments without forced cooling.
Is BAS116T-7-F pin-compatible with BAS216 or BAV99?
No - BAS116T-7-F uses SOT-523 (3-pin, anode-cathode-case) while BAS216 is SOT-363 (6-pin dual) and BAV99 is SOT-363 dual series-switch. Pin count, pin function mapping, and package dimensions differ fundamentally; no mechanical or electrical interchangeability exists without PCB redesign.
Does BAS116T-7-F require special handling for moisture sensitivity?
No - it is rated Moisture Sensitivity Level 1 per J-STD-020D, meaning it may be stored indefinitely at ≤30 °C/85% RH without baking or dry-pack requirements. This simplifies assembly logistics versus MS L3+ components that mandate floor-life tracking and bake-out before reflow.
Can BAS116T-7-F replace BAT54 in low-voltage applications?
Only with circuit validation - BAT54 is a Schottky diode (0.3 V VF) optimized for low-VF, whereas BAS116T-7-F is a silicon PN diode (0.9 V VF) optimized for low leakage. Substituting it in 3.3 V logic clamping may raise forward drop by 600 mV, risking timing violations or increased power loss.
