Product details
Overview
BAT64E6327HTSA1 from Infineon Technologies is a silicon Schottky diode in SCD80 (SOT-23 variant) package, configured as a single anode-cathode device with 40 V reverse voltage rating, 250 mA forward current capability, and ultrafast 5 ns reverse recovery time. It delivers low forward voltage (310 mV typ. at 10 mA) and 4 pF capacitance at 1 V for high-frequency clamping and bias isolation in automotive sensor interfaces.
For engineers reviewing the BAT64E6327HTSA1 datasheet, BAT64E6327HTSA1 pinout, BAT64E6327HTSA1 application, or BAT64E6327HTSA1 equivalent, key selection criteria include its AEC-Q101 qualification, integrated diffused guard ring for ESD robustness, thermal resistance of ≤115 K/W (junction-to-soldering point), and suitability for low-loss meter protection circuits requiring stable leakage performance up to 85°C.
Technical Context
This Schottky diode employs a planar silicon process with diffused guard ring to suppress edge breakdown and ensure reliable operation under transient overvoltage. Its low barrier height yields sub-0.4 V forward drop at 30 mA while maintaining <2 µA reverse leakage at 30 V and 25°C.
The device's 5 ns trr and 4 pF CT at 1 MHz/1 V enable effective RF signal clamping and high-speed sampling protection without introducing significant phase distortion or loading in analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 40 V - supports bias isolation in 24 V automotive systems with 2× safety margin |
| Forward Current | 250 mA - sufficient for continuous LED bias or sensor supply rail clamping |
| Reverse Recovery Time | 5 ns - enables use in >100 MHz RF detector and fast-switching protection paths |
| Forward Voltage | 310 mV typ. at 10 mA - minimizes power loss in low-voltage precision reference paths |
| Diode Capacitance | 4 pF at 1 V, 1 MHz - preserves bandwidth in RF envelope detection and antenna switching |
| Junction Temperature | 150 °C - allows operation in under-hood automotive environments with derated current |
| Thermal Resistance | ≤115 K/W (RthJS) - enables direct PCB copper pour heatsinking without external thermal vias |
Pinout & Package
Package: SCD80 (pin-compatible with SOT-23 but optimized for thermal performance; 1.7 mm × 0.8 mm footprint, 0.7 mm height, cathode marked by bar on terminal 2).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Input node for forward conduction path; connects to protected signal or bias source |
| 2 | Cathode | Output/reference node; marked with cathode bar; ties to ground or lower-potential rail |
| 3 | Not connected | Internally isolated; no electrical function - must remain unconnected in layout |

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, 0.6 pF CT - lower capacitance but reduced voltage margin | Preferred for <1 GHz RF apps where VR margin less critical than CT | Select when minimizing parasitic capacitance outweighs need for 40 V transient immunity |
| BAT54C,215 | 30 V VR, common-cathode dual, 10 ns trr - higher recovery time, dual configuration | Suitable for dual-rail clamping or level-shifting where space permits dual diode | Choose only if dual-diode topology matches schematic and layout constraints |
Compared with NSR0230HT1G and BAT54C,215, BAT64E6327HTSA1 uniquely balances 40 V robustness, 5 ns speed, and 4 pF capacitance - making it optimal for automotive-grade RF front-end protection where both voltage margin and bandwidth preservation are non-negotiable.

FAQ
What is the maximum junction temperature and how does it affect derating?
The absolute maximum junction temperature is 150°C. At ambient temperatures above 85°C, forward current must be derated per the IF vs. TS curves in the datasheet - e.g., at 125°C case temperature, maximum continuous IF drops to ~150 mA for BAT64E6327HTSA1 due to its ≤115 K/W RthJS.
Is BAT64E6327HTSA1 pin-compatible with standard SOT-23 diodes?
It uses the SCD80 package - a dimensionally optimized variant of SOT-23 with identical 1.7 mm × 0.8 mm footprint and 0.7 mm height, but with enhanced thermal pad design. Pin 1 (anode) and Pin 2 (cathode) align with JEDEC SOT-23; Pin 3 is NC and must not be soldered.
Does this diode require special handling for ESD sensitivity?
Yes - BAT64E6327HTSA1 is classified as ESD-sensitive (HBM Class 2, ≥2 kV). Handling requires grounded workstations, ionized air, and static-dissipative packaging; PCB layout must avoid floating traces near the cathode/anode pads to prevent field-induced leakage.
How does the diffused guard ring improve reliability compared to planar-only Schottky diodes?
The integrated diffused guard ring reduces electric field crowding at the mesa edge, suppressing premature avalanche and improving consistency of reverse breakdown voltage across temperature and process variation - validated by AEC-Q101 stress testing including HTGB and TCT.
