Product details
Overview
BAS16WE6433HTMA1 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, level shifting, and clamp protection circuits in automotive body electronics and industrial PLC I/O modules.
For engineers reviewing the BAS16WE6433HTMA1 datasheet, BAS16WE6433HTMA1 pinout, BAS16WE6433HTMA1 application, or BAS16WE6433HTMA1 equivalent, key selection criteria include reverse recovery time, thermal resistance (RthJS ≤ 125 K/W), junction temperature rating (150 °C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This diode operates as a unidirectional, single-anode–cathode switching element with low forward voltage drop (1.25 V at 150 mA) and minimal junction capacitance (2 pF at 0 V). Its fast trr of 4 ns enables use in >100 MHz digital signal conditioning and transient suppression where charge storage must be minimized.
Designed for surface-mount assembly in space-constrained PCBs, it features Pb-free RoHS-compliant termination and meets AEC-Q101 stress testing for humidity, temperature cycling, and mechanical shock-critical for under-hood and control-unit applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V and 48 V automotive supply rail clamping without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in high-frequency logic interface and pulse shaping |
| Forward Current (IF) | 250 mA - sufficient for driving small-signal MOSFET gates or LED indicators |
| Junction Temperature (Tj) | 150 °C - allows operation in engine bay or industrial enclosure environments |
| Thermal Resistance (RthJS) | ≤125 K/W - ensures stable thermal performance on standard FR-4 with minimal copper area |
| Capacitance (CT) | 2 pF at 0 V - minimizes signal distortion in RF-coupled or high-speed data lines |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package, 3-pin configuration with pin 1 = anode, pin 2 = cathode, pin 3 = unused (internal die attach pad, not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; connects to higher-potential node in forward bias |
| Pin 2 | Cathode | Main current exit point; ties to lower-potential or ground-referenced node |
| Pin 3 | Die Attach Pad | Non-functional thermal slug; improves heat conduction when soldered to copper pour |
Key Features

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 NSS12500UW3T1G | trr = 3.5 ns, VF = 1.1 V @ 100 mA, same SOT323 package | Marginally faster switching but lower VR (60 V) limits use in 48 V systems | Select when <60 V rail clamping and sub-4 ns timing are critical |
| Diodes Incorporated BAV99W-7-F | Dual series configuration in SOT323, trr = 4 ns, VR = 70 V per diode | Provides dual-channel capability but requires layout adjustment for single-diode replacement | Select when dual-diode topology matches existing schematic or board layout |
Compared with NSS12500UW3T1G and BAV99W-7-F, BAS16WE6433HTMA1 offers the highest VR (80 V) and AEC-Q101 qualification-making it preferred for automotive 24 V/48 V subsystems where reliability and voltage margin are prioritized over marginal speed gains.

FAQ
Is BAS16WE6433HTMA1 pin-compatible with BAS16W?
Yes. BAS16WE6433HTMA1 uses the same SOT323 package and identical pin 1 (anode)/pin 2 (cathode) assignment as BAS16W. The "E6433HTMA1" suffix denotes tape-and-reel packaging and specific manufacturing lot traceability-not functional or pinout variation.
What is the maximum allowable PCB temperature during reflow soldering?
The device complies with JEDEC J-STD-020D for lead-free reflow, supporting peak temperatures up to 260 °C for ≤30 seconds. Preheat ramp rate must not exceed 3 °C/s, and time above 217 °C must be limited to 60–150 seconds to avoid delamination or metallization damage.
Does this diode require derating at elevated ambient temperatures?
Yes. At 100 °C ambient, the maximum continuous forward current drops to ~125 mA per the IF vs. TS curve for BAS16W. Derating follows a linear thermal limit defined by Ptot = (Tj − TA) / RthJS, with RthJS ≤125 K/W and Tj max = 150 °C.
Can BAS16WE6433HTMA1 replace BAT54 in a 3.3 V logic interface?
No. BAT54 is a Schottky diode (VF ≈ 0.3 V), while BAS16WE6433HTMA1 is a silicon PN diode (VF ≈ 1.25 V at 150 mA). Substituting it would increase forward drop by >900 mV, potentially violating logic-high thresholds in 3.3 V CMOS interfaces.
