Product details
Overview
BAS116T-7 from Diodes Incorporated is a single silicon switching diode in SOT-523 package, rated for 85 V peak repetitive reverse voltage, 215 mA forward current, and exhibiting ultra-low leakage (≤5 nA at 75 V, 25°C). It serves as a precision signal-level clamp or protection diode in high-impedance analog front-ends and automotive sensor interfaces.
For engineers reviewing the BAS116T-7 datasheet, BAS116T-7 pinout, BAS116T-7 application, or BAS116T-7 equivalent, key selection criteria include its 3.0 µs reverse recovery time, 2 pF junction capacitance at 0 V, 0.90–1.25 V forward voltage across 1–150 mA, AEC-Q101 qualification, and SOT-523 footprint compatibility with space-constrained PCB layouts.
Technical Context
The BAS116T-7 is a planar epitaxial silicon PN junction diode optimized for low-leakage signal routing. Its 833 °C/W thermal resistance and 150 mW power dissipation are defined under FR-4 board mounting per AP02001 layout, supporting operation from –65°C to +150°C ambient.
It delivers stable reverse characteristics up to 75 V with IR ≤5 nA at 25°C and ≤80 nA at 150°C, and exhibits VF = 1.0 V typical at IF = 10 mA - enabling predictable biasing in precision detector and sample-hold circuits without significant forward drop error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 85 V - Maximum repetitive reverse voltage before breakdown; defines safe blocking range in clamping or ESD protection paths. |
| IFM | 215 mA - Continuous forward current rating; supports sustained signal-level rectification or logic-level steering. |
| IR @ 75 V, 25°C | ≤5 nA - Ultra-low leakage ensures minimal DC error in high-Z analog nodes like op-amp inputs or ADC reference dividers. |
| trr | 3.0 µs - Reverse recovery time enables use in <1 MHz signal switching applications without excessive switching loss. |
| CT @ 0 V, 1 MHz | 2 pF - Low junction capacitance preserves bandwidth in RF detector or fast transient sensing circuits. |
| VF @ 10 mA | 1.0 V typical - Predictable forward drop simplifies bias network design in discrete level-shifting or voltage threshold detection. |
| RθJA | 833 °C/W - Thermal resistance under standard FR-4 mounting; informs derating above 25°C ambient for reliability-critical deployments. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage signal diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAS16LT-7-F | Same SOT-523 package; 100 V VRRM, 150 mA IFM, IR ≤10 nA at 75 V - higher voltage rating but higher leakage. | Preferred where >85 V transient immunity is required, e.g., CAN bus node protection. | Select if system-level surge tests exceed 85 V; accept ~2× leakage penalty in ultra-low-current nodes. |
| 1N4148WT | SOD-523 package (identical footprint); 100 V VRRM, 300 mA IFM, IR ≤25 nA at 20 V - larger leakage, wider voltage margin. | Used in general-purpose digital logic clamping where leakage tolerance >10 nA is acceptable. | Choose for cost-sensitive consumer designs where AEC-Q101 is not mandated and 25 nA leakage is tolerable. |
Compared with BAS116T-7, BAS16LT-7-F trades leakage performance for higher reverse voltage headroom, while 1N4148WT sacrifices leakage control for broader availability and lower unit cost - making BAS116T-7 optimal for AEC-Q101-compliant, ultra-low-leakage analog signal paths.

FAQ
Is BAS116T-7 suitable for high-frequency RF detection applications?
Yes - with 2 pF junction capacitance at 0 V and 3.0 µs reverse recovery time, the BAS116T-7 supports RF envelope detection up to ~10 MHz. Its low CT minimizes signal attenuation in crystal radio or AM demodulator front-ends, and its consistent VF enables repeatable threshold setting in zero-bias detector configurations.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is +150°C, and the device is rated for continuous operation across –65°C to +150°C ambient. At 25°C ambient, full 150 mW power dissipation is allowed; above that, derating follows the 150 mW linear curve in Figure 1 - e.g., 75 mW at 75°C ambient.
Does BAS116T-7 have a built-in ESD protection structure?
No - the BAS116T-7 is a passive PN junction diode without integrated ESD clamp circuitry. However, its 85 V VRRM and low leakage make it suitable as an external discrete ESD protection element when placed in parallel with sensitive inputs, provided series impedance limits peak current to <500 mA.
Can BAS116T-7 be reflow soldered using standard lead-free profiles?
Yes - the SOT-523 package is qualified for lead-free reflow per J-STD-020D Level 1 moisture sensitivity. Standard JEDEC J-STD-020-compliant peak temperatures up to 260°C are supported; recommended soak time is 60–120 seconds at 150–200°C prior to ramp-up.
