Product details
Overview
BAS16 RFG from Taiwan Semiconductor is a single-die, 150 mA, 75 V general-purpose switching diode in SOT-23 package, featuring 4 ns reverse recovery time, 1.25 V forward voltage at 150 mA, and 2 A non-repetitive surge capability - used in high-frequency switching nodes of SMPS secondary-side rectification.
For engineers reviewing the BAS16 RFG datasheet, BAS16 RFG pinout, BAS16 RFG application, or BAS16 RFG equivalent, key selection criteria include reverse recovery speed, thermal resistance (375 °C/W), junction capacitance (2 pF), surge rating, and RoHS/halogen-free compliance for automated SMT assembly.
Technical Context
The BAS16 RFG is a silicon planar epitaxial switching diode optimized for fast transient response in DC-DC converters and voltage clamping circuits. Its 4 ns trr and low CJ (2 pF) enable operation up to several MHz without significant switching loss or ringing.
Designed for surface-mount automation, it uses matte tin-plated leads compliant with J-STD-002 and meets JESD 201 Class 1A whisker resistance. The SOT-23 package supports moisture sensitivity level 1 and UL 94 V-0 molding compound.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 75 V - Maximum repetitive reverse voltage before breakdown; sets safe operating range in flyback/clamp circuits. |
| IF | 150 mA continuous - Rated forward current defines steady-state conduction capacity in low-power switching paths. |
| IFSM | 2 A @ 1 ms - Non-repetitive surge rating enables handling of inductive kick or startup transients without failure. |
| trr | 4 ns - Reverse recovery time directly impacts switching loss and EMI in high-frequency SMPS designs. |
| VF @ 150 mA | 1.25 V - Forward voltage drop determines conduction loss and thermal load at rated current. |
| CJ | 2 pF @ 1 MHz, 0 V - Low junction capacitance minimizes capacitive coupling and improves high-speed turn-off behavior. |
| RθJA | 375 °C/W - Junction-to-ambient thermal resistance defines power derating above 25°C ambient. |
Pinout & Package
SOT-23 three-terminal plastic package with standard lead pitch (0.95 mm), body dimensions 2.9 × 1.3 × 1.0 mm, and matte tin-plated leads solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node during conduction; polarity-critical for rectification/clamping. |
| Cathode (Pin 2) | Forward current exit point | Marked side of package; ties to lower-potential node or ground reference in flyback snubbers. |
| NC / Heat Sink Pad (Pin 3) | No internal connection | Unused terminal; electrically isolated - no circuit function but contributes to mechanical stability in SMT placement. |
Key Features
| Feature | Design Value |
|---|---|
| Fast reverse recovery | 4 ns trr enables efficient operation in >1 MHz switching topologies without excessive loss or oscillation. |
| Low forward voltage | 1.25 V at 150 mA reduces conduction loss and self-heating in compact, thermally constrained layouts. |
| High surge tolerance | 2 A IFSM withstands transient overcurrents common in inductive load switching and energy recycling circuits. |
| Automated assembly ready | Matte tin plating and SOT-23 footprint comply with J-STD-002 and support high-yield pick-and-place processes. |
| Environmental compliance | RoHS-compliant and halogen-free per IEC 61249-2-21 - satisfies regulatory requirements for consumer and industrial end equipment. |
Applications
| AC-DC Adapter Secondary Rectification | DC-DC Converter Freewheeling Diode |
|---|---|
Use Scenario: Rectifying high-frequency transformer output in compact wall adapters (e.g., 5–12 V, <10 W). IC Role / Device Role / Timing Role: Fast-switching unidirectional current path enabling efficient energy transfer during flyback cycle. Use Value: 4 ns trr and 1.25 V VF minimize conduction and switching losses, improving efficiency and reducing thermal stress on PCB. | Use Scenario: Providing freewheeling path for inductor current in buck converter output stage. IC Role / Device Role / Timing Role: Synchronous or asynchronous flyback diode conducting only during switch-off phase. Use Value: Low CJ (2 pF) prevents parasitic resonance with inductor, while 2 A IFSM handles peak inductor current surges. |
| Voltage Clamp in MOSFET Gate Drive Circuits | Signal-Level Polarity Protection |
Use Scenario: Clamping gate-source voltage spikes during high dv/dt switching of power MOSFETs. IC Role / Device Role / Timing Role: Transient voltage suppressor limiting VGS excursion to safe levels (<±20 V). Use Value: 75 V VRRM provides margin above typical gate drive rails; 4 ns trr ensures rapid clamp activation before device damage. | Use Scenario: Preventing reverse polarity damage to low-voltage logic or sensor inputs (e.g., 3.3 V microcontroller I/O). IC Role / Device Role / Timing Role: Series protection diode blocking reverse current during incorrect power connection. Use Value: 150 mA IF rating supports typical sensor bias currents; SOT-23 footprint allows placement near connectors without board area penalty. |
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 BAS16W-7-F | Same VRRM (75 V), IF (150 mA), trr (4 ns); identical SOT-23 package; marked "A6" same as BAS16 RFG. | No functional difference in SMPS rectification or clamping roles; validated in same reference designs. | Select when dual-sourcing required or ON Semi supply chain preferred. |
| Nexperia PMEG2005AEA,115 | Lower VRRM (20 V), higher IF (500 mA), faster trr (2.5 ns); Schottky architecture - zero Qrr, but limited reverse voltage. | Suitable only where reverse voltage ≤20 V; not interchangeable in 75 V clamp/rectifier positions. | Choose for ultra-low VF (0.32 V) and zero-recovery loss in low-VOUT DC-DC outputs. |
Compared with BAS16W-7-F, the BAS16 RFG offers identical electrical and mechanical specs for drop-in replacement; versus PMEG2005AEA, it trades higher VF and slower trr for 3.75× higher VRRM - critical for universal-input AC-DC or high-side clamp use cases.

FAQ
What is the marking code for the BAS16 RFG?
The BAS16 RFG is laser-marked with "A6" on the top surface of the SOT-23 package. This two-character code is standardized across Taiwan Semiconductor's BAS16 family variants and confirms device identity during visual inspection and automated optical recognition in SMT lines. The marking remains legible after reflow and conforms to JEDEC standards for readability and durability.
Is the BAS16 RFG suitable for use in automotive applications?
The BAS16 RFG is not AEC-Q101 qualified and is not recommended for automotive safety-critical systems. While its TJ range (−65°C to +150°C) meets under-hood temperature extremes, Taiwan Semiconductor does not certify this variant for automotive use. For automotive-grade alternatives, consult TSC's AEC-Q101-qualified BAS16 series or equivalent qualified parts from other manufacturers.
What is the maximum allowable power dissipation for the BAS16 RFG at 70°C ambient?
At 70°C ambient, the BAS16 RFG's maximum allowable power dissipation is 107 mW. This is calculated using RθJA = 375 °C/W and TJ(max) = 150°C: Pd = (150 − 70) / 375 = 0.213 W, derated by 50% per industry practice for reliability - resulting in 107 mW. Exceeding this requires thermal relief or reduced IF.
Does the BAS16 RFG have a specified reverse recovery charge (Qrr)?
No, the official Taiwan Semiconductor datasheet for BAS16 RFG does not specify reverse recovery charge (Qrr). Only trr = 4 ns is provided under defined test conditions (IF = 10 mA, IR = 60 mA, IRR = 10% IR, RL = 100 Ω). Qrr is not characterized or guaranteed for this part; designers requiring Qrr data should select diodes explicitly specifying that parameter, such as certain ultrafast or soft-recovery variants.
How does the BAS16 RFG differ from the BAS16 RF variant?
The BAS16 RFG and BAS16 RF share identical electrical specifications, thermal performance, and SOT-23 packaging. The sole difference is packaging tape specification: "RFG" denotes green (halogen-free) carrier tape per IEC 61249-2-21, while "RF" uses standard tape. Both meet RoHS, but BAS16 RFG adds halogen-free compliance - required for specific environmental certifications in EU and Asia-Pacific markets.
