Product details
Overview
BAS28WH6327XTSA1 from Infineon Technologies is a silicon switching diode in SOT343 package, configured as a parallel pair for high-speed switching applications. It features 80 V reverse voltage rating, 4.5 A non-repetitive surge forward current, 4 ns reverse recovery time, and is AEC-Q101 qualified for automotive use in signal routing and clamping circuits.
For engineers reviewing the BAS28WH6327XTSA1 datasheet, BAS28WH6327XTSA1 pinout, BAS28WH6327XTSA1 application, or BAS28WH6327XTSA1 equivalent, key selection criteria include reverse recovery time under 5 ns, thermal resistance ≤190 K/W, low capacitance (≤2 pF), and AEC-Q101 qualification for under-hood signal conditioning.
Technical Context
This dual-diode configuration operates as two independent, electrically isolated switching elements in a single SOT343 package. Its 4 ns trr and 2 pF CT at 0 V enable clean edge transitions in 10–100 MHz digital signal paths, while the 85 V VRM supports transient-tolerant I/O protection.
The device uses planar epitaxial silicon technology with gold-doped lifetime control to achieve fast carrier recombination. Junction-to-soldering-point thermal resistance of ≤190 K/W allows sustained 200 mA DC operation up to TS = 103°C, validated per AEC-Q101 stress test conditions.

| Reverse Voltage (VR) | 80 V - Supports 24 V and 48 V automotive bus interfaces with margin against load dump transients |
| Reverse Recovery Time (trr) | 4 ns - Enables reliable switching in >50 MHz clock distribution and data line steering |
| Diode Capacitance (CT) | 2 pF @ 0 V, 1 MHz - Minimizes signal loading on high-impedance RF or logic inputs |
| Surge Forward Current (IFS) | 4.5 A @ 1 µs - Withstands ESD-induced current pulses without degradation |
| Junction Temperature (Tj) | 150 °C - Rated for continuous operation in engine control unit (ECU) ambient environments |
| Thermal Resistance (RthJS) | ≤190 K/W - Allows 200 mA DC conduction at solder point temperature ≤103°C |

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 |
|---|---|---|---|
| BAS16W,115 | Single diode in SOT323; trr = 4 ns, CT = 2 pF, VR = 85 V - identical AC specs but no dual configuration | Requires two devices for dual-path protection; higher board area and assembly cost | Select when only one signal path needs protection or space constraints favor smaller footprint per diode |
| MMBD2836LT1G | Dual common-cathode diode in SOT23-3; trr = 6 ns, CT = 2.5 pF, VR = 70 V - slightly slower and lower voltage rating | Limited to 24 V systems; less robust against load dump events in 48 V architectures | Choose for cost-sensitive consumer applications where AEC-Q101 is not required and VR margin <10 V is acceptable |
Compared with BAS16W,115 and MMBD2836LT1G, the BAS28WH6327XTSA1 uniquely delivers dual-channel AEC-Q101 compliance in a compact SOT343, enabling space-efficient, automotive-grade signal routing without sacrificing speed or voltage margin.

FAQ
What is the maximum continuous forward current for BAS28WH6327XTSA1 at 103°C solder point temperature?
The device supports 200 mA DC forward current when the solder point temperature (TS) is held at or below 103°C, as specified in the Absolute Maximum Ratings table. This limit is enabled by its ≤190 K/W junction-to-soldering-point thermal resistance and validated under AEC-Q101 thermal cycling conditions.
Does BAS28WH6327XTSA1 have a common-cathode or common-anode configuration?
BAS28WH6327XTSA1 uses a common-cathode configuration: Pins 2 and 3 are both cathodes tied internally, while Pins 1 and 4 serve as independent anodes. This arrangement simplifies PCB layout for dual-rail clamping and bidirectional signal routing without external wiring.
Is BAS28WH6327XTSA1 suitable for 5 V logic-level signal steering?
Yes - with VF ≤ 1.25 V at IF = 150 mA and trr = 4 ns, it reliably steers 5 V CMOS/TTL signals while adding negligible propagation delay or voltage drop. Its 2 pF capacitance avoids signal rise-time degradation in >20 MHz digital paths.
How does the AEC-Q101 qualification impact reliability in non-automotive applications?
AEC-Q101 qualification subjects BAS28WH6327XTSA1 to accelerated stress tests including HTGB, HTRB, and temperature cycling - resulting in demonstrated failure-in-time (FIT) rates <100 FIT and extended operational life in industrial and medical equipment where long-term stability is critical.
