Product details
Overview
BAT64-04 from Nexperia is a silicon Schottky diode configured as a dual series-connected pair in a single SOT23 package, rated for 40 V reverse voltage, 250 mA forward current, and 5 ns reverse recovery time-designed for low-loss clamping and bias isolation in automotive sensor signal conditioning circuits.
For engineers reviewing the BAT64-04 datasheet, BAT64-04 pinout, BAT64-04 application, or BAT64-04 equivalent, key selection criteria include its 370 mV typical forward voltage at 30 mA, 4 pF capacitance at 1 V, integrated diffused guard ring for ESD robustness, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This dual-series Schottky diode enables bidirectional clamping without external series resistors while maintaining low conduction loss. Its 40 V VR rating supports 24 V automotive supply rail protection, and the 5 ns trr ensures minimal distortion in fast-switching analog front-ends.
The device uses a planar epitaxial process with diffused guard ring to suppress edge breakdown and improve reliability under transient stress. Thermal resistance RthJS is ≤355 K/W (junction-to-soldering-point), validated for operation up to 150 °C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky clamping applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MR6T1G | Single Schottky, 40 V VR, 200 mA IF, SOT-23 - lacks dual-series topology | Requires external series resistor for bidirectional clamp; higher board area | Select when only unidirectional clamping is needed and layout space allows discrete implementation |
| Vishay VS-2EDH04-M3/86A | Common-cathode dual Schottky, 40 V VR, 200 mA IF, SOT-323 - different pinout and thermal profile | Higher RthJS (≤455 K/W) limits power handling in thermally constrained zones | Prefer for cost-sensitive consumer designs where AEC-Q101 is not required |
Compared with NSS40201MR6T1G and VS-2EDH04-M3/86A, BAT64-04 uniquely delivers integrated dual-series clamping in AEC-Q101-qualified SOT23, reducing component count and improving transient response symmetry without sacrificing thermal margin in automotive under-hood placements.

FAQ
What is the pin configuration of BAT64-04 in SOT23?
Pin 1 is the anode of Diode 1, Pin 2 is the internal connection between Diode 1's cathode and Diode 2's anode, and Pin 3 is the cathode of Diode 2. The cathode marking is on Pin 3 side of the package body, confirmed in Nexperia's SOT23 outline drawing SCD80.
Does BAT64-04 support bidirectional clamping?
Yes - its dual-series configuration allows it to clamp positive transients to VCC and negative transients to GND when Pins 1 and 3 are connected across the protected node and reference rail, forming a symmetrical clamp path without external components.
How does BAT64-04 differ from BAT64-04W?
BAT64-04W uses the SOT323 package with lower RthJS (≤155 K/W vs. ≤355 K/W), enabling higher continuous current at elevated board temperatures. Both share identical electrical specs, but BAT64-04W is preferred for thermally dense layouts where solder-point cooling is critical.
Is BAT64-04 suitable for 125 °C ambient automotive applications?
Yes - its 150 °C maximum junction temperature and AEC-Q101 qualification allow operation at 125 °C ambient when derated per the published IF vs. TS curves; at 125 °C, maximum DC forward current is 105 mA for BAT64-04 per Figure 5 in the datasheet.
