Product details
Overview
BAS16WH6433XTMA1 from Nexperia is a silicon high-speed switching diode in SOT323 (SC-70) package, rated for 80 V reverse voltage, 250 mA forward current, and 4 ns reverse recovery time, used in signal routing and clamping circuits of automotive infotainment power management modules.
For engineers reviewing the BAS16WH6433XTMA1 datasheet, BAS16WH6433XTMA1 pinout, BAS16WH6433XTMA1 application, or BAS16WH6433XTMA1 equivalent, key selection criteria include reverse recovery time under 4 ns, low forward voltage at 100 mA (≤1.2 V), AEC-Q101 qualification, and thermal resistance ≤250 K/W for compact PCB layouts.
Technical Context
This diode operates as a unidirectional signal switch with fast turn-off behavior enabled by low junction capacitance (≤2 pF at 0 V) and optimized carrier lifetime control. Its 4 ns trr is measured under standardized 10 mA IF/IR conditions with 100 Ω load, supporting >100 MHz digital signal edge integrity.
The device meets AEC-Q101 stress testing for automotive reliability, including temperature cycling, HTRB, and ESD (HBM ≥8 kV). Its 150 °C maximum junction temperature and Pb-free RoHS-compliant SOT323 package support reflow-soldered deployment in engine control unit (ECU) interface stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports rail-to-rail signal clamping in 24 V automotive systems without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in 100+ MHz clock distribution and data line protection |
| Forward Voltage (VF) | 1.25 V @ 150 mA - minimizes conduction loss in high-duty-cycle logic-level translation paths |
| Junction Capacitance (CT) | 2 pF @ 0 V - preserves signal rise/fall times in RF front-end bias networks |
| Thermal Resistance (RthJS) | 250 K/W - allows sustained 250 mA operation with ≤54 °C case temperature rise in SOT323 layout |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability across -40 to +125 °C ambient operation |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package with three terminals: anode, cathode, and exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry node | Connected to higher-potential signal or supply rail in clamping or steering configurations |
| Cathode (Pin 2) | Current exit node | Connected to reference (GND or lower-voltage rail) to enable forward conduction path |
| Exposed Pad (Pin 3) | Thermal sink only | Must be soldered to copper pour for effective heat dissipation; no electrical connection required |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | 4 ns reverse recovery time ensures minimal signal distortion in >100 MHz digital interfaces |
| AEC-Q101 qualification | Validated for automotive under-hood applications including ECU, ADAS sensor hubs, and body control modules |
| Pb-free RoHS compliance | Meets EU Directive 2011/65/EU with lead content <1000 ppm, compatible with standard SnAgCu reflow profiles |
| Low leakage at high temp | 50 µA IR max at 75 V and 150 °C - maintains signal integrity in hot under-dash environments |
Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|
Use Scenario: Protecting CAN_H/CAN_L lines from ESD transients and bus fault overvoltage in vehicle networking nodes. IC Role / Device Role / Timing Role: Fast-switching clamp diode placed between differential pair and ground, activated within nanoseconds during surge events. Use Value: 4 ns trr prevents false triggering of CAN controller receivers during transient suppression, preserving bit timing accuracy. | Use Scenario: Limiting voltage excursions on D+ and D− lines during hot-plug insertion or ESD events in USB peripheral ports. IC Role / Device Role / Timing Role: Bidirectional clamping diode pair (used in dual configuration) shunting excess energy to VBUS or GND. Use Value: 2 pF junction capacitance avoids signal integrity degradation at 480 Mbps full-speed USB signaling. |
| Industrial PLC Digital Input Conditioning | Smartphone Antenna Tuning Switch |
Use Scenario: Level-shifting and overvoltage protection for 24 V DC digital inputs in programmable logic controllers. IC Role / Device Role / Timing Role: Series switching diode isolating field-side transients from microcontroller GPIO pins. Use Value: 80 V VR rating accommodates industrial surge standards (IEC 61000-4-4, ±2 kV), enabling direct field-wire interface. | Use Scenario: RF path selection and impedance matching control in multi-band LTE/5G antenna front-ends. IC Role / Device Role / Timing Role: High-isolation RF switch element controlling signal routing between antenna and transceiver chains. Use Value: Low 1.25 V VF at 150 mA reduces insertion loss in high-current antenna tuning actuation paths. |
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 |
|---|---|---|---|
| MMBD1619LT1G | trr = 4 ns (same), VF = 1.25 V @ 150 mA (same), but RthJS = 300 K/W vs. 250 K/W | Lower thermal performance limits continuous current in dense layouts | Prefer BAS16WH6433XTMA1 where board space restricts copper area for thermal relief |
| BAS116,115 | trr = 4 ns (same), VR = 100 V (higher), but AEC-Q101 not specified | Lacks automotive qualification; suitable for industrial/commercial only | Select BAS16WH6433XTMA1 when automotive compliance is mandatory per OEM Tier-1 requirements |
Compared with MMBD1619LT1G and BAS116,115, BAS16WH6433XTMA1 uniquely combines AEC-Q101 qualification, 250 K/W thermal resistance, and 4 ns trr in SOT323-making it optimal for space-constrained, thermally demanding automotive signal conditioning.

FAQ
Is BAS16WH6433XTMA1 pin-compatible with standard SOT323 diodes like 1N4148W?
No. While both use SOT323, BAS16WH6433XTMA1 has anode-cathode-exposed pad pinout (1-2-3), whereas 1N4148W uses anode-cathode-no pad (1-2). The exposed pad is critical for thermal performance and must be routed accordingly.
What is the maximum allowable soldering temperature profile for BAS16WH6433XTMA1?
The device complies with JEDEC J-STD-020D for MSLE Level 1, supporting peak reflow temperatures up to 260 °C for ≤30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C must be 60–150 seconds.
Does BAS16WH6433XTMA1 support bidirectional ESD protection?
No. It is a unidirectional diode. For bidirectional protection, two devices must be connected in series opposition (anode-to-anode or cathode-to-cathode), as confirmed in Nexperia Application Note AN10784 for I/O line clamping.
Can BAS16WH6433XTMA1 replace BAS16-02L in existing designs?
Yes, with layout verification. Both share identical electrical specs (trr, VF, VR), but BAS16WH6433XTMA1 uses SOT323 while BAS16-02L uses TSLP-2-1. Pad geometry and thermal pad connection differ-rework of footprint and stencil is required.
