Product details
Overview
BAS116 RFG from Taiwan Semiconductor is a surface-mount silicon switching diode in SOT-23 package, rated for 200 mA mean forward current and 75 V repetitive peak reverse voltage, with 1.25 V forward voltage at 150 mA - used in DC/DC converters and SMPS secondary-side rectification.
For engineers reviewing the BAS116 RFG datasheet, BAS116 RFG pinout, BAS116 RFG application, or BAS116 RFG equivalent, key selection criteria include low VF at high IF, 3.0 µs reverse recovery time, 500 mA non-repetitive surge capability, and halogen-free green compound compliance per IEC 61249-2-21.
Technical Context
The BAS116 RFG is a single-die, general-purpose fast-switching diode optimized for high-frequency operation in compact power conversion stages. Its 3.0 µs reverse recovery time (trr) and 2.0 pF junction capacitance (CJ at 1 MHz, 0 V) support efficient performance in 100–500 kHz DC/DC topologies.
Thermal design is enabled by a 330 °C/W junction-to-ambient thermal resistance (RθJA) under standard PCB mounting, and operation across –55 °C to +150 °C junction temperature ensures reliability in thermally constrained adapters and lighting drivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Mean Forward Current) | 200 mA - supports continuous conduction in low-power SMPS output rectifiers |
| VRRM (Repetitive Peak Reverse Voltage) | 75 V - suitable for 48 V system-derived rails and auxiliary windings |
| VF at IF = 150 mA | 1.25 V - enables low conduction loss in space-constrained on-board converters |
| trr (Reverse Recovery Time) | 3.0 µs - minimizes switching loss in high-frequency flyback and buck converters |
| CJ (Junction Capacitance) | 2.0 pF at 1 MHz, 0 V - reduces capacitive coupling noise in sensitive feedback paths |
| IFSM (Surge Current) | 500 mA @ 1 s - withstands inrush and transient overloads without failure |
| RθJA | 330 °C/W - requires minimal copper area for thermal management on 2-layer boards |
Pinout & Package
Package: SOT-23 - three-terminal, surface-mount plastic package with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 1A whisker resistance; moisture sensitivity level 1 (J-STD-020).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node (e.g., transformer secondary or switch node) |
| Cathode (Pin 2) | Forward current exit point | Connected to output filter capacitor or ground return path |
| Collector / NC (Pin 3) | Internal die substrate connection | Electrically tied to cathode in single-diode configuration; no external function |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-free green compound | Meets IEC 61249-2-21 - eliminates brominated flame retardants for RoHS-compliant manufacturing |
| Low VF at 150 mA | 1.25 V - reduces conduction loss by ~15% vs. standard 1N4148 in same bias conditions |
| Fast trr | 3.0 µs - enables stable operation up to 500 kHz without excessive ringing or EMI |
| High IFSM rating | 500 mA - accommodates startup surges in LED driver and adapter applications without derating |
| SOT-23 footprint | Standardized 2.9 × 1.3 × 1.0 mm outline - compatible with automated pick-and-place and reflow profiles |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBD116 | Identical electrical specs (200 mA, 75 V, 3.0 µs trr), same SOT-23 package, but marked "116" not "JV" | No functional difference in SMPS or adapter use; identical thermal and surge ratings | Select when dual-sourcing required or ON Semi supply chain preferred |
| Diodes Incorporated BAV116 | Same VF (1.25 V @ 150 mA), but higher IR (10 nA @ 75 V/25°C) and slightly longer trr (4.0 µs) | Acceptable in less noise-sensitive lighting applications; may require margin check in high-frequency flyback | Prefer BAS116 RFG where low leakage or <3.5 µs trr is critical |
Compared with MMBD116 and BAV116, the BAS116 RFG offers the lowest reverse leakage (5 nA) and fastest trr (3.0 µs) among these SOT-23 75 V switching diodes - making it optimal for high-efficiency, thermally constrained DC/DC designs where leakage-induced standby loss or switching noise must be minimized.

FAQ
What is the marking code for BAS116 RFG?
The BAS116 RFG is laser-marked with "JV" on the device top surface. This two-character code uniquely identifies the BAS116 RFG variant within Taiwan Semiconductor's SOT-23 diode family and is verified per the official datasheet revision F2001. The "RFG" suffix in the ordering code indicates green (halogen-free) molding compound, which does not affect the marking.
Is BAS116 RFG pin-compatible with BAS16 or BAV116?
Yes, the BAS116 RFG uses the standard SOT-23 package with anode (Pin 1), cathode (Pin 2), and substrate (Pin 3) pinout - identical to BAS16 and BAV116. However, BAS16 has only 100 V VRRM and higher VF; BAV116 shows 4.0 µs trr and 10 nA IR. So while PCB layout is interchangeable, electrical behavior differs.
What is the maximum junction temperature rating for BAS116 RFG?
The BAS116 RFG has a specified junction temperature range of –55 °C to +150 °C, validated per absolute maximum ratings in the F2001 datasheet. This allows reliable operation in enclosed lighting fixtures and industrial DC/DC modules where ambient temperatures exceed 85 °C, provided thermal resistance to ambient remains ≤330 °C/W.
Does BAS116 RFG meet J-STD-020 moisture sensitivity requirements?
Yes, the BAS116 RFG is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it can be stored indefinitely at ≤30 °C/85% RH without baking prior to reflow. This eliminates pre-bake steps in high-throughput SMT lines and supports standard JEDEC-compliant handling for the BAS116 RFG.
What is the typical reverse recovery time of BAS116 RFG under standard test conditions?
The BAS116 RFG has a maximum reverse recovery time (trr) of 3.0 µs, measured at IF = 10 mA, IR = 10 mA, RL = 100 Ω, and Irr = 1 mA. This value is confirmed in the Electrical Specifications table of the F2001 datasheet and enables stable operation in 300–500 kHz switching converters without added snubbing.
