Diodes Incorporated BAT760-7

Overview

BAT760-7 from Diodes Incorporated is a surface-mount Schottky barrier rectifier in SOD323 package, rated for 30 V peak reverse voltage and 1 A average forward current, with typical forward voltage of 270 mV at 100 mA and 350 mV at 1 A, used in low-loss DC power rail clamping and reverse polarity protection circuits.

For engineers reviewing the BAT760-7 datasheet, BAT760-7 pinout, BAT760-7 application, or BAT760-7 equivalent, key selection criteria include its low VF at high IF, guard ring–enabled transient robustness, 250 mW power dissipation limit, and automotive-qualified counterpart BAT760Q for harsh-environment designs.

Technical Context

This Schottky diode employs platinum-silicide (PtSi) or similar low-barrier metal–semiconductor junction to achieve sub-350 mV forward drop at 1 A, enabling higher efficiency than standard PN rectifiers in space-constrained 12 V/24 V supply rails. Its guard ring construction suppresses edge breakdown under fast transients, improving reliability in automotive load-dump or inductive-switching environments.

Thermal resistance of 500 °C/W (junction-to-ambient, FR-4 board) dictates strict layout adherence to recommended pad dimensions; junction capacitance of 25 pF at 5 V enables use in moderate-speed signal clamping (<10 MHz), though not optimized for RF switching.

FAQ

What is the maximum junction temperature for BAT760-7 during continuous 1 A operation?

The BAT760-7 has a maximum junction temperature of +150 °C. At 1 A average forward current and 25 °C ambient, junction temperature rise is approximately 125 °C (1 A² × 0.35 Ω × 500 °C/W), reaching ~150 °C - confirming operation at absolute thermal limit. Derating is required above 25 °C ambient or with reduced copper area.

Is BAT760-7 suitable for use in automotive applications?

The BAT760-7 is not AEC-Q101 qualified; however, its guard ring construction and JEDEC-compliant reliability testing support industrial-grade automotive use. For certified automotive applications, Diodes offers the BAT760Q variant, which undergoes extended temperature cycling, humidity testing, and failure analysis per AEC-Q101 Rev H.

How does the SOD323 package affect thermal performance compared to larger packages?

The SOD323's small footprint (1.3 mm × 1.7 mm) limits heat-spreading area, resulting in high RθJA of 500 °C/W on standard FR-4. To maintain safe junction temperature at 1 A, designers must use ≥10 mm² of 2-oz copper connected to both terminals via multiple vias - unlike larger packages like SMA or SMB that achieve <100 °C/W with minimal copper.

Can BAT760-7 replace a standard PN junction diode in existing designs?

Yes - BAT760-7 can directly replace PN diodes like 1N4148 or 1N4001 in low-voltage, high-efficiency applications due to identical SOD323 footprint and superior VF (350 mV vs. 700–1100 mV). However, its higher IR at elevated temperatures requires verification in battery-powered circuits where leakage impacts shelf life.
