Product details
Overview
BAT6402VH6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SC79 package, configured as a single anode-cathode device with 40 V reverse voltage rating, 250 mA forward current, and 5 ns reverse recovery time-used for low-loss bias isolation and clamping in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT6402VH6327XTSA1 datasheet, BAT6402VH6327XTSA1 pinout, BAT6402VH6327XTSA1 application, or BAT6402VH6327XTSA1 equivalent, key selection criteria include its 310 mV typical forward voltage at 10 mA, 4 pF capacitance at 1 V, AEC-Q101 qualification, RoHS-compliant SMD packaging, and thermal resistance of ≤115 K/W (junction-to-soldering point).
Technical Context
This Schottky diode employs a planar silicon process with integrated diffused guard ring to suppress edge breakdown and ensure stable reverse leakage-critical for precision analog front-ends. Its low VF and fast trr stem from optimized metal-semiconductor junction design rather than epitaxial layer tuning.
Rated for operation up to 150 °C junction temperature and qualified per AEC-Q101, it supports automotive-grade reliability under thermal cycling and humidity exposure. The SC79 package enables high-density placement while maintaining thermal performance via direct die attach to leadframe.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports 24 V automotive supply rail clamping with 67 % safety margin |
| Forward Voltage (VF) | 310 mV typ. @ 10 mA - minimizes conduction loss in low-power bias networks |
| Reverse Recovery Time (trr) | 5 ns max - enables clean switching in <10 MHz signal path protection |
| Diode Capacitance (CT) | 4 pF @ 1 V, 1 MHz - preserves bandwidth in RF detector and antenna switch applications |
| Thermal Resistance (RthJS) | ≤115 K/W - allows 250 mW dissipation with ≤28.8 °C rise above solder point |
| Junction Temperature (Tj) | 150 °C - meets under-hood ambient requirements per AEC-Q101 stress testing |
| ESD Rating | HBM Class 2 (≥2 kV) - requires handling per ESD-sensitive device protocols |
Pinout & Package
SC79 package: ultra-small surface-mount plastic case (1.3 × 0.8 × 0.6 mm), anode and cathode terminals exposed on bottom side, no thermal pad, compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Current entry node | Connected to higher-potential node during forward conduction; must be routed with low-inductance trace in clamp paths |
| Cathode (K) | Current exit node | Typically tied to reference plane or signal return; serves as clamping reference in overvoltage protection |
Key Features
| Feature | Design Value |
|---|---|
| Integrated diffused guard ring | Suppresses edge leakage and improves VR consistency across temperature and process variation |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, mechanical shock, and HTRB stress |
| Pb-free RoHS-compliant construction | Meets EU Directive 2011/65/EU; compatible with lead-free reflow soldering (JEDEC J-STD-020) |
| Low 0.6 nH series inductance | Minimizes voltage overshoot during fast transient clamping (e.g., ISO 7637-2 pulse 1/2a) |
Applications
| Automotive Sensor Signal Protection | Low-Power Metering Bias Isolation |
|---|---|
Use Scenario: Protecting Hall-effect and crankshaft position sensor outputs from load dump transients in 12 V vehicle systems. IC Role / Device Role / Timing Role: Clamping diode placed between sensor output and ground, conducting only during overvoltage events ≥40 V. Use Value: Prevents latch-up in downstream op-amps by limiting excursion to ≤0.3 V above rail using 310 mV VF, enabling direct interface without level-shifting. | Use Scenario: Isolating reference voltage nodes in portable energy meters powered by coin-cell batteries. IC Role / Device Role / Timing Role: Bidirectional DC blocking element preventing battery drain through measurement circuitry during standby. Use Value: 2 µA max IR at 30 V ensures <1 nA leakage into 1 MΩ input impedance, preserving >10-year battery life. |
| RF Detector Input Clamp | High-Speed Logic-Level Translation |
Use Scenario: Front-end protection for 2.4 GHz Wi-Fi receiver detectors subject to ESD and RF rectification artifacts. IC Role / Device Role / Timing Role: Shunt limiter across detector diode anode and ground, activated only above 40 V RF envelope peaks. Use Value: 4 pF CT avoids detuning of matching network; 5 ns trr prevents distortion of sub-ns RF pulses. | Use Scenario: Level shifting between 3.3 V MCU GPIO and 5 V industrial I/O modules with mixed-voltage signaling. IC Role / Device Role / Timing Role: Passive open-drain translator where BAT6402V conducts only when MCU pulls low, sinking current into 5 V rail. Use Value: 310 mV VF ensures logic LOW remains <0.4 V at 10 mA sink, meeting TTL and CMOS input thresholds reliably. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | 30 V VR, 200 mA IF, 0.8 nH LS, SOD-523 package | Lower voltage rating limits use in 24 V systems; smaller footprint reduces thermal mass | Select when board space is constrained and system VR ≤30 V; verify RthJS = 200 K/W does not exceed thermal budget |
| BAT54C,215 | Common-cathode dual configuration, 30 V VR, 200 mA IF, SOT-23 package | Dual topology enables complementary clamping but increases parasitic capacitance to 10 pF | Choose for dual-rail protection (e.g., RS-485 bus); avoid where <6 pF CT is required for RF integrity |
Compared with NSR0230HT1G and BAT54C,215, BAT6402VH6327XTSA1 offers superior 40 V robustness and lower 4 pF capacitance-making it preferred for 24 V automotive clamping and high-frequency detector protection where voltage margin and bandwidth are critical.

FAQ
Is BAT6402VH6327XTSA1 pin-compatible with BAT64-02W?
Yes-both share identical SC79 package dimensions and anode/cathode terminal layout. However, BAT64-02W has higher RthJS (≤355 K/W vs. ≤115 K/W), limiting usable power dissipation in thermally constrained layouts despite identical pinout.
What is the maximum allowable PCB copper area for optimal thermal performance?
Per Infineon Application Note AN077, a minimum 10 mm² copper pour connected directly to both terminals achieves RthJA ≈ 220 K/W. Larger areas improve cooling but yield diminishing returns beyond 25 mm² due to SC79's intrinsic RthJS limitation of 115 K/W.
Does this diode support bidirectional ESD protection?
No-it is a unidirectional Schottky diode. For bidirectional ESD protection, a TVS array like ESD5Z3.3T1G must be used. BAT6402VH6327XTSA1 clamps only positive transients relative to cathode; negative excursions exceed VR and cause breakdown.
Can BAT6402VH6327XTSA1 replace BAT54 in existing designs?
Only if VR ≥40 V is required and CT ≤4 pF is acceptable. BAT54 has 30 V VR and ~10 pF CT-so substitution risks overvoltage failure in 24 V systems and bandwidth degradation in RF paths. Review trr (5 ns vs. 4–6 ns) and VF (310 mV vs. 370 mV) for impact on conduction loss.
