Product details
Overview
BAW56WE6327HTSA1 from Infineon Technologies is a silicon double diode in common-anode configuration, rated for 80 V reverse voltage, 200 mA forward current, and 4 ns reverse recovery time-optimized for high-speed switching in signal routing and ESD protection circuits within automotive infotainment and industrial I/O interfaces.
For engineers reviewing the BAW56WE6327HTSA1 datasheet, BAW56WE6327HTSA1 pinout, BAW56WE6327HTSA1 application, or BAW56WE6327HTSA1 equivalent, key selection criteria include its SC74 (SOT-363) package thermal resistance (RthJS = 240 K/W), low 2 pF junction capacitance at 0 V, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This dual diode operates with two anodes tied internally to a shared cathode terminal, enabling bidirectional clamping or steering functions in high-frequency signal paths. Its 4 ns reverse recovery time and 2 pF capacitance support operation up to ~100 MHz in RF front-end protection and data-line transient suppression.
The device is characterized across temperature (–65 °C to +150 °C) with IR ≤ 0.15 µA at VR = 70 V and TA = 25 °C, and VF = 1.25 V max at IF = 150 mA-ensuring stable conduction under pulsed loads and elevated ambient conditions typical in engine control units and sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transients without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in >25 MHz digital signal lines |
| Junction Capacitance (CT) | 2 pF @ 0 V, 1 MHz - minimizes signal loading in USB 2.0 and CAN FD data paths |
| Forward Current (IF) | 200 mA DC - sufficient for logic-level clamping and LED indicator drive |
| Thermal Resistance (RthJS) | 240 K/W - allows 250 mW power dissipation with ≤90 °C case temperature rise |
| AEC-Q101 Qualified | Yes - validated for automotive electronics per stress test requirements |
Pinout & Package
BAW56WE6327HTSA1 is housed in an SC74 (SOT-363) surface-mount package measuring 2.9 mm × 1.9 mm × 1.1 mm, with 6 terminals in a symmetrical layout and no defined Pin 1 orientation in tape-and-reel delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Anode 1 / Anode 2 | Independent input nodes for dual-channel clamping or steering |

| 4, 5 | Anode 1 / Anode 2 (duplicate) | Redundant anode connections for improved current sharing and solder joint reliability |
| 6 | Cathode (common, duplicate) | Secondary cathode pad for enhanced thermal conduction and mechanical stability |
Key Features

| 4 ns reverse recovery time | Reduces switching loss and ringing in 10–50 MHz clock and data lines |
| RthJS = 240 K/W | Supports continuous 250 mW dissipation with <90 °C junction-to-solder-point rise |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, HTRB, and ESD testing |
Applications
| Automotive CAN FD Transceiver Protection | Industrial RS-485 Data Line Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 | Same SC74 package, but 100 V VR and 3 ns trr; VF = 1.25 V @ 150 mA | Slightly higher voltage margin; faster switching but identical footprint | Select when system transients exceed 80 V or timing-critical paths demand sub-4 ns recovery |
| ESD5Z3.3T5G | Single-channel, 3.3 V clamping voltage, 0.5 pF CT, SOD-523 package | Designed for low-voltage I/O protection-not interchangeable due to topology and voltage rating | Use only for 3.3 V logic-level ESD suppression where dual-channel common-anode function is unnecessary |
Compared with BAW56WE6327HTSA1, BAV99W offers tighter timing and higher VR but same thermal profile, while ESD5Z3.3T5G serves fundamentally different low-voltage clamping roles-neither is pin-compatible, but both address adjacent protection needs in automotive and industrial designs.

FAQ
What is the maximum allowable junction temperature for BAW56WE6327HTSA1?
The absolute maximum junction temperature (Tj) is 150 °C, verified per AEC-Q101 thermal stress testing. Operation above this limit risks permanent degradation of the silicon die and bond wires. Derating curves in the datasheet show permissible forward current decreases linearly above 90 °C case temperature to maintain Tj ≤ 150 °C.
Is BAW56WE6327HTSA1 pin-compatible with BAW56S or BAW56U variants?
No-while all share the SC74 (SOT-363) outline, BAW56WE6327HTSA1 corresponds specifically to the BAW56W variant with RthJS = 240 K/W and TS ≤ 90 °C rating. BAW56S uses the same package but has RthJS = 260 K/W and TS ≤ 85 °C; BAW56U differs in marking and thermal limits. Mechanical fit does not guarantee electrical or thermal equivalence.
Does this diode meet RoHS and REACH requirements?
Yes-BAW56WE6327HTSA1 is Pb-free and RoHS compliant per EU Directive 2011/65/EU, with full material declarations available in Infineon's compliance documentation. It also satisfies REACH SVHC thresholds (<0.1% w/w) for all listed substances, confirmed via supplier-controlled manufacturing and third-party lab testing.
Can BAW56WE6327HTSA1 be used in place of a single discrete diode like 1N4148?
No-it is a dual common-anode diode intended for paired signal paths (e.g., differential lines), not single-ended replacement. Substituting it for a 1N4148 would require circuit redesign to utilize both anodes and the shared cathode. Its 2 pF capacitance and 4 ns trr differ significantly from 1N4148's 4 pF and 4 ns typical, making direct functional substitution invalid without validation.
