Product details
Overview
BAW56SE6327BTSA1 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. It is AEC-Q101 qualified for automotive switching applications including signal routing, level shifting, and ESD protection in CAN/LIN transceiver interfaces.
For engineers reviewing the BAW56SE6327BTSA1 datasheet, BAW56SE6327BTSA1 pinout, BAW56SE6327BTSA1 application, or BAW56SE6327BTSA1 equivalent, key selection criteria include reverse recovery speed, thermal resistance (240 K/W), junction temperature rating (150 °C), and SC74 package compatibility with high-density PCB layouts.
Technical Context
This dual diode operates in common-anode topology, enabling bidirectional clamping or steering functions in signal path protection circuits. Its 2 pF capacitance at 0 V and 4 ns trr support >100 MHz digital signal integrity in automotive serial bus receivers.
The device features low forward voltage (1.25 V max at 150 mA) and tight thermal resistance control (RthJS = 240 K/W), allowing sustained operation up to 90 °C case temperature while maintaining stable leakage (<50 µA at 70 V, 150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 80 V - supports 24 V automotive supply rail transient suppression without breakdown |
| Reverse Recovery Time (trr) | 4 ns - enables clean switching in 100+ MHz data lines like LIN/CAN physical layer |
| Forward Current (IF) | 200 mA - sufficient for driving logic-level inputs or biasing small-signal transistors |
| Junction Temperature (Tj) | 150 °C - meets under-hood automotive thermal requirements per AEC-Q101 stress testing |
| Diode Capacitance (CT) | 2 pF @ 0 V, 1 MHz - minimizes signal loading on high-speed digital I/O pins |
| Thermal Resistance (RthJS) | 240 K/W - allows 250 mW power dissipation with ≤90 °C case temperature in SC74 package |
Pinout & Package
BAW56SE6327BTSA1 is housed in an SC74 (SOT-363) surface-mount package with six terminals in a 2.9 mm × 1.9 mm footprint. Pin 1 is marked by a dot or notch; orientation is symmetric and non-directional in tape-and-reel delivery.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | Anode (common) | Shared cathode return path for dual-diode conduction; connects to system ground or reference rail |
| 3, 4 | Cathode 1 | Independent cathode for first diode; used for signal clamping or steering in Channel A |
| 5, 6 | Cathode 2 | Independent cathode for second diode; enables parallel or differential protection paths |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability across temperature cycling, humidity, and mechanical shock |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99,215 | Same SC74 package, but 70 V VR and 3 ns trr; higher IR (1 µA @ 70 V) | Better for ultra-fast timing-critical paths; less robust for 24 V automotive transients | Select when trr < 3.5 ns is mandatory and VR margin ≥10 V suffices |
| MMBD7000LT1G | SC70 package, 100 V VR, 6 ns trr, 1.25 V VF; RthJS ≈ 300 K/W | Higher voltage tolerance but slower switching and worse thermal performance | Choose for cost-sensitive industrial designs where 100 V surge immunity outweighs speed needs |
Compared with BAV99,215, BAW56SE6327BTSA1 offers +10 V reverse margin critical for automotive load dump compliance; versus MMBD7000LT1G, it delivers 33% faster switching and 20% lower thermal resistance-key for thermally constrained automotive ECUs.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 test conditions. Derating begins above 90 °C case temperature due to the 240 K/W thermal resistance; at 100 °C TS, maximum DC forward current drops to ~175 mA to maintain Tj ≤ 150 °C.
Is BAW56SE6327BTSA1 compatible with lead-free reflow profiles?
Yes-it is RoHS-compliant and qualified for standard Pb-free reflow profiles (J-STD-020D), with peak temperature tolerance up to 260 °C for 30 seconds. The SC74 package uses matte tin plating and passes intermetallic growth and solder joint reliability testing.
Does the common-anode configuration support independent cathode biasing?
Yes-pins 3/4 and 5/6 are electrically isolated cathodes. Each can be biased to different reference voltages (e.g., one to 3.3 V, another to 5 V), enabling dual-rail clamping or mixed-voltage signal steering without cross-talk.
How does reverse recovery time vary with operating temperature?
trr increases from 4 ns at 25 °C to approximately 6.5 ns at 125 °C, as confirmed by Infineon's characterization data. This variation remains within specification limits for LIN, CAN, and RS-485 signaling rates, with no measurable impact on bit error rate below 1 Mbps.
