Product details
Overview
BAT5402LRHE6327XTSA1 from Infineon Technologies is a silicon Schottky diode in SOT23 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 BAT5402LRHE6327XTSA1 datasheet, BAT5402LRHE6327XTSA1 pinout, BAT5402LRHE6327XTSA1 application, or BAT5402LRHE6327XTSA1 equivalent, key selection criteria include its 0.4 nH series inductance, 230 mW power dissipation at TS ≤ 135 °C, and guaranteed 2 µA max reverse leakage at 25 V - critical for precision analog front-ends and ESD-protected I/O stages.
Technical Context
This dual common-cathode Schottky diode integrates two independent anode terminals sharing one cathode, enabling bidirectional clamping or dual-path biasing without cross-conduction. Its guard ring protection ensures stable breakdown behavior under transient stress, and the low 0.4 nH internal inductance minimizes ringing during fast edge transitions.
Designed for operation up to 150 °C junction temperature, it delivers consistent VF performance across -65 °C to +150 °C storage range, with thermal resistance RthJS ≤ 65 K/W from junction to soldering point - optimized for compact PCB layouts with limited copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports rail-to-rail clamping in 24 V automotive systems without breakdown |
| Forward Current (IF) | 200 mA - sufficient for biasing op-amp input protection networks and low-power signal routing |
| Reverse Recovery Time (trr) | 5 ns - enables clean switching in >10 MHz signal path protection and high-speed metering inputs |
| Forward Voltage (VF) | 400 mV @ 10 mA - reduces conduction loss and self-heating in continuous bias applications |
| Reverse Leakage (IR) | 2 µA @ 25 V - preserves accuracy in high-impedance sensor interfaces and reference dividers |
| Thermal Resistance (RthJS) | ≤65 K/W - allows reliable operation at TS ≤ 135 °C on minimal copper land patterns |
| Diode Capacitance (CT) | 10 pF @ 1 V - maintains signal integrity in <100 MHz analog sensing paths |
Pinout & Package
SOT23-3 package with standard lead pitch (0.95 mm), molded plastic body, and RoHS-compliant matte tin plating. Dimensions: 2.9 × 1.3 × 1.0 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent input node for first clamping path; connects to protected signal line |
| Pin 2 | Cathode (common) | Shared return node for both diodes; ties to reference or clamp rail |
| Pin 3 | Anode 2 | Independent input node for second clamping path; used for differential or redundant protection |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown under ESD or surge stress, improving long-term reliability in unshielded harnesses |
| Low series inductance (LS = 0.4 nH) | Minimizes voltage overshoot during nanosecond-scale transients in CAN/LIN bus I/O protection |
| Pb-free, RoHS-compliant packaging | Enables direct use in automotive ECUs requiring full material compliance documentation |
| Common cathode dual configuration | Reduces component count in bidirectional TVS replacement or dual-rail clamp designs |
Applications
| Automotive Sensor Signal Conditioning | Industrial Analog Input Protection |
|---|---|
Use Scenario: Protecting thermistor, RTD, or Hall-effect sensor outputs from load dump and ISO 7637-2 pulses in engine control modules. IC Role / Device Role: Dual-anode clamping diode shunting overvoltage to ground or supply rail while preserving DC bias. Use Value: 5 ns trr and 0.4 nH LS ensure sub-10 ns response to 100 V/µs transients without oscillation or false triggering. | Use Scenario: Safeguarding 4–20 mA transmitter inputs against wiring faults and field-induced surges in PLC analog modules. IC Role / Device Role: Common-cathode dual diode providing symmetrical positive/negative rail clamping on differential input pairs. Use Value: 2 µA IR at 25 V prevents loading of high-Z current-loop sense resistors, maintaining ±0.1% measurement accuracy. |
| USB Port ESD Clamping | Low-Power Metering Reference Biasing |
Use Scenario: Secondary-level ESD protection for USB 2.0 D+/D− lines in portable diagnostic tools with limited board space. IC Role / Device Role: Low-capacitance (10 pF) dual Schottky clamp diverting IEC 61000-4-2 events away from USB transceivers. Use Value: 400 mV VF at 10 mA enables clamping below 3.3 V logic thresholds without forward conduction during normal operation. | Use Scenario: Providing stable bias current to precision voltage references in energy metering ICs operating at elevated ambient temperatures. IC Role / Device Role: Dual-anode isolation diode delivering matched, temperature-stable current to REF+ and REF− pins. Use Value: RthJS ≤ 65 K/W sustains 200 mA bias capability up to 135 °C board temperature, eliminating thermal derating in sealed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54CLT3G | Same SOT23-3 package, common cathode, but higher VF (450 mV @ 10 mA) and 10 ns trr | Less suitable for high-speed signal lines above 5 MHz due to slower recovery | Select when cost sensitivity outweighs speed requirements and 50 mV VF penalty is acceptable |
| BAT54C,215 | Identical electrical specs but qualified to AEC-Q101; RthJS = 75 K/W (vs. 65 K/W) | Approved for automotive safety-critical modules where qualification is mandatory | Choose when formal AEC-Q101 certification is required, accepting slightly lower thermal efficiency |
Compared with SBAT54CLT3G and BAT54C,215, BAT5402LRHE6327XTSA1 offers the fastest recovery (5 ns), lowest thermal resistance (≤65 K/W), and tightest VF consistency - making it optimal for space-constrained, high-transient environments where speed and thermal headroom are prioritized over formal qualification.

FAQ
Is BAT5402LRHE6327XTSA1 AEC-Q101 qualified?
No. The datasheet explicitly states "BAT54-02LRH is not qualified according AEC Q101". It meets all electrical and thermal specifications for automotive use but lacks formal qualification testing. For AEC-Q101–required applications, BAT54C,215 is the functionally equivalent qualified alternative.
What is the maximum allowable board temperature (TS) for continuous operation?
The absolute maximum soldering-point temperature (TS) is 135 °C, as specified in the "Maximum Ratings" table. Operation beyond this limit risks irreversible degradation of the die attach and wire bonds, even if junction temperature remains within the 150 °C rating.
Can BAT5402LRHE6327XTSA1 be used in place of a single Schottky diode?
Yes - either anode can be used independently with the cathode grounded or tied to a reference rail, effectively functioning as two discrete Schottky diodes. Pin 2 is the shared cathode; Pins 1 and 3 are isolated anodes with identical electrical characteristics.
Does the 0.4 nH series inductance apply to both diodes individually?
Yes. The 0.4 nH LS value is measured per diode path (anode-to-cathode), confirmed by the "Type Package Configuration LS(nH)" table entry for BAT54-02LRH. This low inductance is intrinsic to the SOT23-3 leadframe geometry and bond wire layout, not a shared parasitic.
