Product details
Overview
BAT5405WE6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SOT-323 (SC-70) package, configured as a single anode-cathode junction with 30 V reverse voltage rating, 200 mA forward current capability, and ultra-low 5 ns reverse recovery time. It delivers 400 mV forward voltage at 10 mA, enabling efficient clamping and bias isolation in space-constrained automotive sensor signal conditioning circuits.
For engineers reviewing the BAT5405WE6327HTSA1 datasheet, BAT5405WE6327HTSA1 pinout, BAT5405WE6327HTSA1 application, or BAT5405WE6327HTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, 110 °C/W junction-to-soldering-point thermal resistance, and guaranteed ≤2 µA reverse leakage at 25 V - critical for low-power rail protection and precision analog front-ends.
Technical Context
This Schottky diode uses a guard ring–protected planar structure to suppress edge breakdown and ensure stable reverse leakage across temperature. Its low 1.4 nH series inductance and 10 pF capacitance at 1 V support high-frequency clamping up to ~100 MHz without resonance issues.
The device operates with a maximum junction temperature of 150 °C and is rated for repetitive peak forward current of 300 mA under 50% duty cycle conditions, making it suitable for intermittent surge suppression in CAN transceiver I/O protection and microcontroller reset line conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - supports operation across 24 V automotive rails with 2× safety margin |
| Forward Voltage (VF) | 400 mV @ 10 mA - minimizes conduction loss in low-voltage bias networks |
| Reverse Recovery Time (trr) | 5 ns - enables clean switching in >10 MHz signal clamping applications |
| Reverse Leakage (IR) | ≤2 µA @ 25 V - preserves accuracy in high-impedance sensor bias paths |
| Thermal Resistance (RthJS) | 110 °C/W - allows 200 mA continuous operation at ≤110 °C board temperature |
| Junction Temperature (Tj) | 150 °C - qualified for under-hood automotive environments per AEC-Q101 |
| Package | SOT-323 (SC-70) - 2.1 × 1.25 × 0.95 mm footprint for dense PCB layouts |
Pinout & Package
SOT-323 (SC-70) plastic surface-mount package with gull-wing leads; moisture sensitivity level (MSL) 1, RoHS-compliant, Pb-free termination.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry terminal | Connected to higher-potential node during forward conduction; requires trace width ≥0.25 mm for 200 mA |
| Cathode (Pin 2) | Current exit terminal | Internally tied to substrate; must be routed to lowest system potential for clamping |
| Heat Sink / Exposed Pad (Pin 3) | Thermal path only | No electrical connection; soldered to copper pour for RthJS reduction |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring protection | Prevents premature edge breakdown at VR = 30 V, ensuring consistent reverse leakage over lifetime |
| AEC-Q101 qualification | Validated for automotive electronics including engine control modules and body domain controllers |
| Low VF temperature coefficient | +0.2 mV/°C drift - maintains stable bias point across –40 °C to +125 °C ambient |
| Ultra-fast trr | 5 ns measured with 10 mA IF/IR, enabling use in 20 Mbps digital signal line protection |
Applications
| Automotive Sensor Signal Clamping | Microcontroller Reset Line Protection |
|---|---|
Use Scenario: Clamp transient spikes on analog sensor outputs (e.g., pressure, temperature) in 12 V vehicle networks. IC Role / Device Role / Timing Role: Fast-acting shunt diode placed between signal line and ground to divert ESD/ISO 7637-2 pulses. Use Value: 5 ns trr ensures sub-10 ns response to 1 kV/µs transients, preventing ADC saturation in downstream MCU. | Use Scenario: Protect microcontroller reset pin from negative voltage excursions during power sequencing. IC Role / Device Role / Timing Role: Reverse-biased Schottky isolator blocking –0.3 V to –2 V glitches while passing valid logic-high reset signals. Use Value: 400 mV VF at 10 mA limits voltage drop to <0.5 V, preserving reset timing margins in 3.3 V systems. |
| USB Data Line ESD Suppression | Low-Power Bias Isolation in RF Front-Ends |
Use Scenario: Secondary ESD clamp on USB 2.0 D+/D− lines adjacent to primary TVS devices. IC Role / Device Role / Timing Role: Low-capacitance (10 pF) shunt element that activates before main TVS reaches breakdown. Use Value: 10 pF CT at 1 V avoids signal integrity degradation above 480 Mbps data rates. | Use Scenario: Isolate DC bias from RF amplifier input while maintaining signal path continuity. IC Role / Device Role / Timing Role: Forward-biased Schottky used as active DC block in LNA bias tee networks. Use Value: 1.4 nH LS minimizes inductive reactance (<1 Ω) up to 2.4 GHz, preserving impedance matching. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | 0.2 A IF, 30 V VR, SOD-323 package, RthJS = 220 °C/W | Higher thermal resistance limits continuous current to 120 mA at 85 °C ambient | Select when board space permits larger SOD-323 and thermal budget allows derating |
| BAT54CWS-E3-08 | Common-cathode dual configuration, same SOT-323, VF = 420 mV @ 10 mA | Enables dual-rail clamping but occupies same footprint as single BAT5405W | Choose for simultaneous protection of complementary signal pairs (e.g., RS-485 A/B) |
Compared with NSR0230HT1G and BAT54CWS-E3-08, BAT5405WE6327HTSA1 offers superior thermal performance (110 vs. 220 °C/W) and single-diode simplicity for point-of-load clamping, while maintaining identical voltage ratings and speed.

FAQ
What is the maximum allowable soldering temperature for BAT5405WE6327HTSA1?
The device is qualified for reflow soldering per JEDEC J-STD-020, with peak temperature of 260 °C for ≤30 seconds. Hand soldering must not exceed 350 °C for more than 3 seconds per pad to avoid delamination or junction damage.
Does BAT5405WE6327HTSA1 support bidirectional ESD protection?
No - it is a unidirectional Schottky diode with anode-to-cathode polarity. For bidirectional protection, two devices must be connected in series opposition, or a dedicated bidirectional TVS such as ESD5Z5.0T1G should be used instead.
Can BAT5405WE6327HTSA1 replace BAT54-05W in existing designs?
Yes - BAT5405WE6327HTSA1 is the tape-and-reel packaged variant of BAT54-05W with identical electrical specs, thermal characteristics, and SOT-323 footprint. The "E6327" suffix denotes packaging format; no layout or schematic changes are required.
Is the cathode pin internally connected to the exposed pad in SOT-323?
No - the exposed pad (Pin 3) is electrically isolated and serves only as a thermal path. The cathode is exclusively at Pin 2; connecting the pad to circuit ground improves thermal performance but does not alter electrical functionality.
