Product details
Overview
BAS16TA from Diodes Incorporated is a surface-mount fast-switching silicon switching diode in SOT23 package, rated for 75 V peak repetitive reverse voltage, 300 mA forward current, and 4.0 ns reverse recovery time. It serves as a general-purpose signal-level switching element in digital logic interfaces, clamp circuits, and high-speed sample-and-hold systems.
For engineers reviewing the BAS16TA datasheet, BAS16TA pinout, BAS16TA application, or BAS16TA equivalent, key selection criteria include reverse recovery speed, low forward voltage at 10 mA (≤0.855 V), leakage current stability up to +150°C (≤50 µA at VR = 75 V), and compatibility with automated SMT assembly on FR-4 PCBs.
Technical Context
The BAS16TA operates as a single PN-junction silicon diode optimized for high-speed switching rather than power rectification. Its design emphasizes low stored charge and minimal minority-carrier lifetime to achieve sub-5 ns tRR under standardized IF = IR = 10 mA test conditions.
It exhibits a typical forward voltage of 0.715 V at 1 mA and rises to 1.25 V at 150 mA, with reverse leakage held below 1.0 µA at 75 V and 25°C. Junction-to-ambient thermal resistance is 357°C/W on standard 1-inch² 2 oz copper pad layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time | 4.0 ns - Enables reliable operation in >100 MHz digital switching and pulse shaping circuits |
| Peak Repetitive Reverse Voltage | 75 V - Supports use in 5 V–48 V logic interface clamping and signal routing |
| Forward Current (Continuous) | 300 mA - Sufficient for driving small-signal loads including LED indicators and gate inputs |
| Forward Voltage @ 10 mA | ≤0.855 V - Minimizes voltage drop and power loss in low-voltage signal paths |
| Reverse Leakage @ 75 V | ≤1.0 µA at 25°C - Ensures high isolation integrity in precision analog sampling switches |
| Junction-to-Ambient RθJA | 357°C/W - Requires minimal copper area for thermal management in space-constrained layouts |
Pinout & Package
Package: SOT23 - Surface-mount plastic package with matte tin-plated alloy 42 leadframe, moisture sensitivity level 1 per J-STD-020, and UL 94V-0 flammability rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node during conduction; marked by cathode band on package top view |
| Cathode (Pin 2) | Forward current exit point | Internally tied to substrate; functions as reference node for clamping and protection circuits |
| NC / Heat Sink (Pin 3) | No internal connection | Unused terminal; may be left floating or grounded for mechanical stability without electrical impact |
Key Features
| Feature | Design Value |
|---|---|
| Fast switching performance | 4.0 ns reverse recovery time enables clean edge transitions in 100+ MHz clock distribution networks |

| Wide temperature operation | -55°C to +150°C operating range allows deployment in automotive under-hood and industrial control environments |
Applications
| Digital Logic Clamping | High-Speed Sample-and-Hold |
|---|---|
Use Scenario: Protecting CMOS input pins from voltage overshoot during bus contention or hot-plug events. IC Role / Device Role: Fast-acting shunt clamp that conducts only when input exceeds VCC or drops below GND. Use Value: 4.0 ns tRR prevents metastability in 50 MHz–100 MHz data buses while maintaining <1 µA leakage at standby. | Use Scenario: Holding analog voltage levels during ADC conversion cycles in data acquisition systems. IC Role / Device Role: Low-charge-injection switch isolating hold capacitor from input source during acquisition phase. Use Value: Sub-5 ns turn-off ensures minimal droop and settling error in 12-bit+ sampling accuracy requirements. |
| Signal Routing Multiplexer | ESD Protection Interface |
Use Scenario: Selecting between multiple sensor outputs feeding a shared microcontroller ADC channel. IC Role / Device Role: Passive analog switch enabling bidirectional signal path selection without active control logic. Use Value: 0.855 V VF at 10 mA preserves signal fidelity across 0–3.3 V input ranges with <0.5% gain error. | Use Scenario: Secondary-level transient suppression on USB, I²C, or UART lines before integrated ESD arrays. IC Role / Device Role: Low-capacitance (2.0 pF) shunt element diverting fast transients to ground or rail. Use Value: 2.0 pF CT minimizes signal distortion on 10 Mbps differential lines while handling ±8 kV contact discharge per IEC 61000-4-2. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fast-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MMBD4148-7-F | Identical tRR (4.0 ns), same SOT23 package, but slightly higher VF (0.855 V @ 10 mA vs. BAS16TA's 0.715 V @ 1 mA) | Preferred where tighter VF matching at low currents is required in precision bias networks | Select MMBD4148 if legacy design validation exists or if dual sourcing across Diodes' portfolio is needed |
| BAS21-7-F | Higher VR (200 V), slower tRR (50 ns), same package - trade-off of voltage rating for speed | Suitable for 12–24 V industrial control where surge immunity outweighs switching speed | Choose BAS21 only when reverse voltage margin >100 V is mandatory and nanosecond-scale timing is not critical |
Compared with MMBD4148-7-F and BAS21-7-F, the BAS16TA delivers optimal balance of speed (4.0 ns), low forward voltage at low current (0.715 V @ 1 mA), and industry-standard SOT23 compatibility-making it preferred for high-frequency signal routing where both timing fidelity and power efficiency matter.

FAQ
Is BAS16TA pin-compatible with MMBD4148?
Yes - both devices use identical SOT23 package with anode (Pin 1), cathode (Pin 2), and unused terminal (Pin 3) pinout. Electrical characteristics match closely, including 4.0 ns reverse recovery time and 75 V VRRM, enabling direct substitution in most signal-switching applications without layout change.
What is the maximum junction temperature for continuous operation?
The BAS16TA supports continuous operation from –55°C to +150°C junction temperature. At ambient temperatures above 75°C, derating applies: power dissipation must be reduced linearly from 350 mW at 25°C to zero at 150°C, per the published derating curve in DS12003 Rev. 33–2.
Does BAS16TA meet AEC-Q101 for automotive use?
No - the standard BAS16TA is not AEC-Q101 qualified. Only the variant BAS16Q (e.g., BAS16Q-7-F) carries AEC-Q101 qualification, PPAP capability, and is manufactured in IATF 16949-certified facilities. BAS16TA is intended for commercial and industrial applications.
How does BAS16TA perform under high-temperature reverse bias?
At +150°C and VR = 75 V, reverse leakage is specified ≤50 µA - a 50× increase over room-temperature leakage (≤1.0 µA), but still within usable limits for clamping and isolation in thermally demanding environments such as motor control feedback paths.
