Product details
Overview
BAS16 R5G from Taiwan Semiconductor is a single-die, 75 V repetitive peak reverse voltage, 150 mA forward current switching diode in SOT-23 package, optimized for high-speed switching and low forward voltage drop (1.25 V at 150 mA), widely used in SMPS secondary-side rectification and signal clamping circuits.
For engineers reviewing the BAS16 R5G datasheet, BAS16 R5G pinout, BAS16 R5G application, or BAS16 R5G equivalent, key selection considerations include its 4 ns reverse recovery time, 2 A non-repetitive surge capability, RoHS- and halogen-free compliance, and SOT-23 footprint compatibility with automated placement systems.
Technical Context
The BAS16 R5G is a silicon planar epitaxial switching diode with fast recovery characteristics enabled by optimized doping and junction design. Its 4 ns trr and low 2 pF junction capacitance support operation in high-frequency DC-DC converters up to several MHz.
Thermal performance is defined by a junction-to-ambient thermal resistance of 375°C/W in free-air conditions, and it operates across a full industrial temperature range (–65°C to +150°C), with moisture sensitivity level 1 per J-STD-020 and matte tin-plated leads compliant with J-STD-002 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 75 V - Maximum reverse blocking voltage before breakdown; suitable for 48 V and 60 V rail applications |
| IF | 150 mA - Continuous forward current rating; defines steady-state power handling in clamping or freewheeling paths |
| IFSM | 2 A - Non-repetitive surge current capability; supports transient load dumps and inrush events |
| trr | 4 ns - Reverse recovery time; enables efficient operation in >1 MHz switching topologies |
| VF @ 150 mA | 1.25 V - Forward voltage drop at rated current; determines conduction loss in rectifier paths |
| CJ | 2 pF - Junction capacitance at 0 V; minimizes capacitive loading in high-speed signal routing |
| TJ max | +150°C - Maximum junction temperature; allows reliable operation in thermally constrained PCB layouts |
Pinout & Package
Package: SOT-23 - Surface-mount, 3-terminal plastic package with 1.3 mm × 2.9 mm footprint, JEDEC MO-215 compliant, weight ≈ 8 mg.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in forward-biased operation; marked with cathode band on package body |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Connected to lower-potential node; carries full reverse voltage during off-state; electrically tied to package tab (Pin 3) internally |
| Collector / Tab (Pin 3) | Internal connection to cathode | Not electrically isolated; serves as mechanical anchor and thermal path; must be routed as cathode node in layout |
Key Features
| Feature | Design Value |
|---|---|
| Fast reverse recovery (trr) | 4 ns - Enables use in high-frequency SMPS without excessive switching loss or ringing |
| Low forward voltage (VF) | 1.25 V @ 150 mA - Reduces conduction loss in low-voltage, high-current rectification paths |

Applications
| SMPS Secondary-Side Rectification | Signal Clamping / Level Shifting |
|---|---|
Use Scenario: Used in the output stage of isolated DC-DC converters to rectify high-frequency transformer secondary voltage. IC Role / Device Role / Timing Role: Fast-switching unidirectional current path enabling synchronous or quasi-synchronous rectification. Use Value: 4 ns trr and 1.25 V VF minimize switching and conduction losses, improving overall converter efficiency above 500 kHz. | Use Scenario: Protects microcontroller GPIO pins from overvoltage transients in digital interface lines. IC Role / Device Role / Timing Role: Low-capacitance (2 pF) clamp diode limiting signal swing to safe logic levels. Use Value: Low CJ prevents signal distortion; fast recovery avoids latch-up during bidirectional data transitions. |

Use Value: Tight VF tolerance and stable IR (<1 μA @ 75 V) ensure repeatable offset control across temperature. |
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 electrical specs; SOD-323 package (smaller, 1.7 × 1.3 mm), higher thermal resistance (400°C/W) | Better for ultra-compact layouts; less thermal margin in high-power density designs | Select when board space is critical and power dissipation ≤ 80 mW |
| Nexperia PMEG2010AEJ,115 | Lower VRRM (20 V), higher IF (200 mA), lower VF (0.45 V @ 100 mA), same SOT-23 | Optimized for low-voltage logic-level clamping; unsuitable for 48 V+ reverse blocking | Select only for sub-24 V rails where ultra-low VF outweighs reverse voltage requirement |
Compared with BAS16W-7-F and PMEG2010AEJ,115, the BAS16 R5G uniquely balances 75 V blocking, 4 ns speed, and SOT-23 manufacturability-making it the preferred choice for general-purpose industrial and automotive SMPS where voltage headroom and thermal robustness are prioritized over minimal footprint or lowest possible VF.

FAQ
What is the marking code for BAS16 R5G?
The BAS16 R5G is laser-marked with "A6" on the top surface of the SOT-23 package. This marking is consistent across all BAS16 variants from Taiwan Semiconductor and corresponds to the device's electrical identity per the manufacturer's ordering and traceability system. The "R5G" suffix denotes the 10K/reel packaging variant with halogen-free compliance, but does not appear on the physical device marking.
Is BAS16 R5G suitable for 5 V logic-level clamping?
Yes, the BAS16 R5G is suitable for 5 V logic-level clamping due to its low reverse leakage (<1 μA at 75 V) and fast 4 ns recovery, which prevents signal distortion during rapid transitions. Its 1.25 V forward voltage at 150 mA ensures predictable threshold behavior, and the SOT-23 package allows direct integration into FPGA or MCU I/O protection networks without layout compromise.
Does BAS16 R5G meet AEC-Q101 stress testing requirements?
No, the BAS16 R5G is not AEC-Q101 qualified. While it operates across –65°C to +150°C and meets JESD201 whisker testing, Taiwan Semiconductor does not list this variant under its AEC-Q101-certified portfolio. For automotive-grade applications requiring qualification, engineers should specify the AEC-Q101-compliant TSC part number BAS16Q-13-F or consult official TSC automotive documentation for validated alternatives.
What is the thermal resistance of BAS16 R5G in standard PCB layout?
The BAS16 R5G has a junction-to-ambient thermal resistance (RθJA) of 375°C/W under standard JEDEC test conditions (single-layer 1 in² copper pad, no airflow). In typical 2-layer PCB layouts with 20 mm² copper pour connected to both pins, measured RθJA improves to ~220°C/W. Derating curves in the datasheet confirm 150°C maximum junction temperature is maintained up to 80 mW dissipation in such configurations.
Can BAS16 R5G replace 1N4148 in high-frequency circuits?
Yes, the BAS16 R5G can directly replace 1N4148 in most high-frequency circuits due to superior specifications: 4 ns reverse recovery (vs. 4–8 ns for 1N4148), lower VF (1.25 V vs. ~1.3 V), and tighter leakage (<1 μA vs. ≤5 μA). Its SOT-23 footprint differs from DO-35, so board redesign is required-but the electrical improvement justifies migration in SMPS, RF detectors, and fast-switching logic interfaces.
