Product details
Overview
BAS28WE6327BTSA1 from Infineon Technologies is a silicon switching diode in SOT343 package, configured as a parallel pair for high-speed signal routing. It delivers 4 ns reverse recovery time, 80 V reverse voltage rating, and 200 mA continuous forward current-optimized for automotive AEC-Q101-compliant digital logic clamping and data line protection.
For engineers reviewing the BAS28WE6327BTSA1 datasheet, BAS28WE6327BTSA1 pinout, BAS28WE6327BTSA1 application, or BAS28WE6327BTSA1 equivalent, key selection criteria include trr ≤ 4 ns, VR = 80 V, IR ≤ 0.1 µA at 75 V/25°C, and thermal resistance RthJS ≤ 190 K/W for junction-to-soldering-point dissipation in compact PCB layouts.
Technical Context
This dual-diode device integrates two identical, electrically isolated silicon PN junctions in a single SOT343 surface-mount package. Its parallel-pair configuration enables independent signal path handling without cross-coupling, supporting bidirectional transient suppression and fast edge steering in serial interface lines.
The diode operates with VF = 715 mV at IF = 1 mA and CT = 2 pF at VR = 0 V/1 MHz-critical for minimizing capacitive loading on high-frequency GPIOs and clock distribution nets while maintaining low conduction loss during active switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V industrial bus and 48 V automotive supply rail transient clamping |
| Reverse Recovery Time (trr) | 4 ns - enables reliable operation up to ~100 MHz digital signal edges without tail current distortion |
| Forward Voltage (VF) | 715 mV @ 1 mA - ensures minimal voltage drop in low-current bias and level-shifting circuits |
| Diode Capacitance (CT) | 2 pF @ 0 V - preserves signal integrity on USB 2.0, I²C, and SPI lines with <1% impedance mismatch |
| Junction Temp (Tj) | 150 °C - qualified for under-hood automotive environments per AEC-Q101 stress testing |
| Thermal Resistance (RthJS) | ≤190 K/W - allows 250 mW power dissipation with ≤47.5 K rise above solder point temperature |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Primary input node for first switching path; routed to signal source or pull-up net |
| Pin 2 | Cathode of Diode 1 | Output node tied to protected IC input or ground reference; forms clamp path |
| Pin 3 | Anode of Diode 2 | Independent anode for second signal channel; electrically isolated from Diode 1 |
| Pin 4 | Cathode of Diode 2 | Second clamp output; enables dual-rail ESD protection or differential signal steering |

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 |
|---|---|---|---|
| BAS216WE6327XTSA1 | Higher VR = 100 V; same SOT343 package and trr = 4 ns | Better suited for 48 V telecom power rail monitoring where higher standoff is required | Select when system-level transients exceed 85 V peak and thermal margin permits 200 mW derating |
| MMBD7000LT1G | Single-diode SOT23; trr = 4 ns but VF = 1.25 V @ 100 mA and CT = 2.5 pF | Lacks dual-channel integration; requires two devices for parallel-pair functionality | Choose only if board space allows discrete placement and cost-per-channel is prioritized over layout efficiency |
Compared with BAS28WE6327BTSA1, BAS216WE6327XTSA1 offers higher voltage headroom without sacrificing speed or footprint, while MMBD7000LT1G trades integration for lower unit cost but increases assembly complexity and parasitic capacitance.

FAQ
What is the maximum allowable soldering temperature profile for BAS28WE6327BTSA1?
The SOT343 package is rated for standard reflow per IPC/JEDEC J-STD-020, with peak temperature ≤260°C for ≤30 seconds. Preheat ramp rate must not exceed 3°C/s, and time above 217°C shall be limited to 60–150 seconds to avoid internal delamination or bond wire damage.
Does BAS28WE6327BTSA1 support bidirectional ESD protection?
Yes-each diode functions as a unidirectional clamp, but the parallel-pair configuration allows bidirectional protection when anodes are tied to signal lines and cathodes to VCC or ground. This implements IEC 61000-4-2 Level 4 (±8 kV contact) compliance when used with appropriate series impedance.
Can BAS28WE6327BTSA1 replace BAT54S in existing designs?
No-BAT54S uses SOT23-3 with common-cathode topology, whereas BAS28WE6327BTSA1 is SOT343 with independent anode/cathode pairs. Pinout, thermal performance (RthJS = 190 vs. ~300 K/W), and VF vs. IF curves differ significantly; redesign of layout and bias network is required.
Is there a halogen-free version of this diode?
Yes-BAS28WE6327BTSA1 is fully halogen-free per IEC 61249-2-21, with bromine and chlorine content below 900 ppm each. The molding compound and leadframe plating meet JEDEC JS709C requirements for green electronics manufacturing.
