Product details
Overview
BAS16GW from Nexperia is a high-speed switching diode in SOD123 package, designed for fast voltage transition and low-loss signal routing in compact power and interface circuits. It delivers trr ≤ 4 ns reverse recovery time, VR = 100 V maximum reverse voltage, Cd ≤ 1.5 pF capacitance, IF = 215 mA continuous forward current, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the BAS16GW datasheet, BAS16GW pinout, BAS16GW application, or BAS16GW equivalent, key selection criteria include reverse recovery speed under pulsed IF/IR conditions, thermal resistance to ambient (Rth(j-a) = 350 K/W on FR4), leakage performance at elevated temperature, and compatibility with reflow-soldered SOD123 footprints.
Technical Context
The BAS16GW operates as a unidirectional silicon switching diode optimized for rapid turn-off in DC-DC converter snubbers, level-shifting interfaces, and protection clamps where sub-5 ns recovery and minimal junction capacitance are critical. Its low VF (855 mV @ 10 mA) and tight trr distribution support stable timing in high-frequency flyback and charge-pump topologies.
Thermal design relies on its SOD123 mounting pad geometry and specified Rth(j-sp) = 58 K/W to cathode solder point. The device sustains repetitive peak forward current up to 500 mA (tp ≤ 0.5 ms) and non-repetitive surges to 4 A (tp = 1 µs), enabling robust transient handling in automotive load-dump and ESD-coupled paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports high-side switching in 48 V automotive systems and industrial 24–48 V rails without breakdown. |
| Reverse Recovery Time (trr) | 4 ns - enables operation up to ~100 MHz switching frequencies with minimal switching loss in hard-switched converters. |
| Forward Voltage (VF) | 855 mV @ 10 mA - reduces conduction loss in low-current bias and signal-clamp applications. |
| Diode Capacitance (Cd) | 1.5 pF @ 1 MHz, 0 V - minimizes capacitive loading on high-impedance nodes such as oscillator feedback paths. |
| Reverse Leakage (IR) | 0.5 µA @ 80 V, 25 °C - ensures stable DC blocking in precision reference and sensor signal conditioning circuits. |
| Junction Temperature (Tj) | 150 °C - allows sustained operation in under-hood automotive environments and sealed industrial enclosures. |
| AEC-Q101 Qualified | Validated for automotive electronics per stress-test requirements - suitable for engine control, body electronics, and ADAS subsystems. |
Pinout & Package
SOD123 surface-mount plastic package: 2-terminal, single-diode configuration with cathode (K) and anode (A) leads exposed on opposite ends of a 3.75 mm × 1.7 mm body. Cathode marked by band; standard footprint per Figure 10 (reflow) with 2.36 mm × 0.91 mm solder land.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Current exit terminal; connected to ground or lower-potential node; thermal path to PCB via cathode pad (Rth(j-sp) = 58 K/W). |
| 2 | Anode (A) | Current entry terminal; tied to input rail or switched node; no internal thermal enhancement beyond standard SOD123 copper exposure. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | trr ≤ 4 ns ensures minimal tail current during commutation - critical for reducing EMI in SMPS and gate-drive clamp circuits. |
| Low leakage at high temperature | IR = 50 µA @ 80 V, 150 °C maintains signal integrity in hot under-hood environments without false triggering. |
| Small SMD footprint | SOD123 package (3.75 × 1.7 mm) enables dense layout in space-constrained modules like LED drivers and USB-C PD controllers. |
| Low junction capacitance | Cd ≤ 1.5 pF avoids signal distortion in RF detector and high-speed logic interface applications. |
| AEC-Q101 qualification | Validated for automotive use - eliminates need for additional qualification testing in Tier-1 ECU and lighting designs. |
Applications
| Automotive Load-Dump Protection | DC-DC Converter Snubber |
|---|---|
Use Scenario: Clamping transient overvoltage spikes (up to ±100 V) induced by alternator load dump in 12 V vehicle electrical systems. IC Role / Device Role / Timing Role: Fast-acting clamp diode placed across input filter capacitor to shunt surge energy before it reaches downstream regulators. Use Value: 4 ns trr and 100 V VR ensure immediate conduction within nanoseconds of spike onset, limiting peak voltage to safe levels for 3.3 V/5 V PMICs. |
Use Scenario: Suppressing voltage overshoot across MOSFET drain-source during turn-off in synchronous buck converters operating >500 kHz. IC Role / Device Role / Timing Role: RCD snubber diode that conducts only during brief switch-node voltage reversal, then blocks rapidly. Use Value: 1.5 pF capacitance prevents resonance with snubber resistor and capacitor, while 4 ns trr avoids reverse conduction delay that degrades efficiency. |
| Level-Shifting Interface | ESD-Safe Signal Clamp |
Use Scenario: Translating logic signals between 3.3 V microcontroller I/O and 5 V peripheral bus lines in industrial PLC modules. IC Role / Device Role / Timing Role: Bidirectional clamping diode (anode grounded, cathode to signal line) limiting swing to VDD + 0.85 V and GND − 0.7 V. Use Value: Low VF (855 mV @ 10 mA) ensures precise clamping threshold; 1.5 pF capacitance avoids signal edge degradation at 10–25 MHz data rates. |
Use Scenario: Protecting analog sensor inputs (e.g., thermistor, Hall-effect) from ±8 kV contact ESD events per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance clamp diode connected between signal line and supply rail to divert ESD current away from ADC front-end. Use Value: 0.5 µA IR at 25 °C preserves high-impedance sensor bias accuracy; AEC-Q101 qualification confirms robustness against repeated ESD stress. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MMBD1201LT1G | trr = 4 ns (same), but VR = 70 V and Cd = 2.0 pF; not AEC-Q101 qualified. | Limited to 24 V industrial systems; unsuitable for 48 V automotive or load-dump scenarios requiring 100 V rating. | Select when cost sensitivity outweighs automotive qualification and higher VR is unnecessary. |
| Vishay 1N4148WS | trr = 4 ns (same), VR = 100 V (same), but IR = 25 nA @ 20 V (lower leakage), and no AEC-Q101 certification. | Preferred in low-leakage analog signal paths (e.g., precision comparators), but requires separate automotive validation. | Choose for lab instrumentation or consumer devices where leakage < 30 nA is prioritized over automotive compliance. |
Compared with MMBD1201LT1G and 1N4148WS, the BAS16GW uniquely combines 100 V VR, 4 ns trr, AEC-Q101 qualification, and 1.5 pF capacitance - making it the only option qualified for production automotive switching and clamping without derating or additional qualification effort.

FAQ
Is BAS16GW suitable for 48 V automotive battery systems?
Yes. With VR = 100 V and AEC-Q101 qualification, the BAS16GW is rated for continuous operation in 48 V nominal systems and withstands load-dump transients up to ISO 7637-2 Pulse 5a (100 V). Its 150 °C Tj rating supports under-hood deployment without derating.
What is the recommended reflow profile for BAS16GW in SOD123 package?
Nexperia specifies JEDEC J-STD-020-compliant reflow for SOD123: peak temperature 260 °C (max), time above 217 °C ≤ 60 s, ramp-up rate ≤ 3 °C/s. Footprint dimensions (2.36 mm × 0.91 mm pad) and solder paste volume must match Figure 10 in the datasheet to ensure reliable cathode thermal connection.
How does BAS16GW compare to standard 1N4148 in high-frequency switching?
The BAS16GW offers identical trr (4 ns) but lower Cd (1.5 pF vs. typical 4 pF for 1N4148), tighter IR specification (0.5 µA vs. 5 µA), and AEC-Q101 qualification. Its SOD123 package also provides better thermal coupling than DO-35, improving reliability in sustained high-frequency operation.
Can BAS16GW be used in bidirectional ESD protection configurations?
No. As a single PN-junction diode, BAS16GW conducts only anode-to-cathode. For bidirectional ESD protection, two devices must be used back-to-back (anode-to-anode), or a dedicated TVS array like PESD5V0S1BA should be selected - BAS16GW serves only unidirectional clamping or rectification roles.
