Product details
Overview
BAT5402VH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-23 package configured as a common cathode dual diode, rated for 30 V reverse voltage, 200 mA forward current, and 5 ns reverse recovery time, used for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT5402VH6327XTSA1 datasheet, BAT5402VH6327XTSA1 pinout, BAT5402VH6327XTSA1 application, or BAT5402VH6327XTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, low 400 mV forward voltage at 10 mA, 2 µA max reverse leakage at 25 V, and thermal resistance of 105 K/W (junction-to-soldering point).
Technical Context
This dual common-cathode Schottky diode integrates two independent anodes sharing one cathode terminal, enabling bidirectional clamping or dual-path protection without cross-conduction. Its guard ring structure ensures stable breakdown behavior and robust ESD immunity up to ±8 kV HBM.
The device operates with minimal forward voltage drop across its full rated current range (0.1–100 mA), maintaining sub-500 mV VF up to 10 mA at 25°C and exhibiting only 10 pF capacitance at 1 V reverse bias-critical for high-frequency signal integrity in CAN bus interface protection and ADC input guarding.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Reverse Voltage | 30 V - supports rail-to-rail clamping on 24 V automotive supply lines without breakdown |
| Forward Current | 200 mA - enables continuous bias current for dual-channel analog front-ends |
| Reverse Recovery Time | 5 ns - prevents switching transients from coupling into adjacent high-speed signal paths |
| Forward Voltage | 400 mV @ 10 mA - reduces power loss and self-heating in compact PCB layouts |
| Reverse Leakage | 2 µA @ 25 V - preserves signal accuracy in precision sensor bias networks |
| Junction Temp | 150 °C - meets under-hood temperature requirements per AEC-Q101 stress testing |
| Thermal Resistance | 105 K/W (RthJS) - allows reliable operation at 126 °C case temperature under 230 mW dissipation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual common-cathode Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Single diode, SOD-123, 30 V/200 mA, 5 ns trr, but no dual configuration | Requires two devices and extra PCB area for dual-path protection | Select when discrete layout flexibility outweighs space savings of integrated dual die |
| BAT54C,215 | Same SOT-23 dual common-cathode topology, but not AEC-Q101 qualified | Limited to industrial/commercial use; lacks automotive stress test validation | Choose for cost-sensitive non-automotive designs where qualification is not mandated |
Compared with NSR0230HT1G and BAT54C,215, BAT5402VH6327XTSA1 uniquely delivers AEC-Q101 compliance, validated thermal performance at 126 °C case temperature, and guaranteed 5 ns trr in a single SOT-23 footprint-making it the only option qualified for under-hood automotive signal protection.

FAQ
What is the maximum junction temperature rating for BAT5402VH6327XTSA1?
The absolute maximum junction temperature is 150 °C, verified per AEC-Q101 stress testing protocols. Derating begins at 126 °C case temperature, where the device sustains full 200 mA forward current with 230 mW total power dissipation under defined PCB thermal conditions.
Does BAT5402VH6327XTSA1 support bidirectional ESD protection?
Yes-the common-cathode dual configuration allows simultaneous clamping of both anodes to the shared cathode, enabling symmetrical protection between two signal lines and ground or supply rails. It achieves ±8 kV HBM ESD immunity per IEC 61000-4-2 Level 4 when properly laid out with low-inductance grounding.
Can BAT5402VH6327XTSA1 replace BAT54C in automotive designs?
Only if AEC-Q101 qualification is not required. BAT5402VH6327XTSA1 shares identical electrical specs and SOT-23 pinout with BAT54C, but adds automotive-grade reliability validation-including temperature cycling, humidity testing, and mechanical shock-making it mandatory for Tier 1 automotive applications.
What is the typical forward voltage at 100 mA and 125 °C?
At 100 mA and 125 °C, the forward voltage is approximately 800 mV, as confirmed by the VF vs. IF curve in the official datasheet (Figure 6). This value reflects thermal derating behavior critical for high-temperature power rail clamping applications.
