STMicroelectronics BAT30-07P6FILM

Overview

BAT30-07P6FILM from STMicroelectronics is a dual parallel-configured Schottky barrier diode in SOT-666 package, rated for 30 V repetitive peak reverse voltage and 300 mA continuous forward current per diode, with typical junction capacitance of 14 pF at 1 V and ultra-low forward voltage drop (530 mV at 300 mA, Tj = 25 °C), optimized for high-frequency switching in DC-DC converters and OR-ing circuits.

For engineers reviewing the BAT30-07P6FILM datasheet, BAT30-07P6FILM pinout, BAT30-07P6FILM application, or BAT30-07P6FILM equivalent, key selection criteria include low conduction loss, negligible reverse recovery, parallel diode configuration for current sharing, thermal resistance of 600 °C/W (junction-to-ambient, epoxy PCB), and compatibility with automated SMT assembly on space-constrained boards.

Technical Context

The BAT30-07P6FILM integrates two identical Schottky diodes in parallel within a single SOT-666 leadframe, enabling redundant current paths without external paralleling. Its low 0.53 V forward voltage at 300 mA reduces power dissipation versus silicon PN diodes, while sub-10 ns reverse recovery time eliminates switching tail currents in buck converter freewheeling paths.

Thermal performance is defined by R_th(j-a) = 600 °C/W on FR4 PCB with 35 µm copper, and maximum junction temperature is rated to 150 °C. The device operates with reverse leakage ≤0.5 µA at 5 V and ≤3 µA at 25 V (Tj = 25 °C), supporting stable biasing in low-power signal routing applications.

Key Specifications

Pinout & Package

SOT-666 is a 6-pin surface-mount package with exposed thermal pad, measuring 1.50–1.70 mm × 1.50–1.70 mm × 0.45–0.60 mm height. It features three anode-cathode pairs arranged for compact dual-diode integration; pins 1/2/3 form one diode, pins 4/5/6 form the second, with shared cathode connection in parallel configuration.

FAQ

What is the electrical configuration of BAT30-07P6FILM?

BAT30-07P6FILM contains two identical Schottky diodes connected in parallel within a single SOT-666 package: pins 1 and 4 are independent anodes, pins 2 and 5 are internally shorted cathodes, and pins 3 and 6 connect to the exposed thermal pad. This configuration provides matched VF and thermal coupling without external wiring.

Can BAT30-07P6FILM replace a single SOT-23 Schottky diode in existing designs?

Yes, provided the PCB footprint is updated to SOT-666 and the circuit benefits from parallel diode operation. Pin mapping differs significantly: BAT30-07P6FILM has six terminals (two anodes, one shared cathode, thermal pad), unlike 3-pin SOT-23. Layout redesign and thermal pad soldering are mandatory for functional replacement.

What is the maximum allowable continuous forward current for the entire device?

The device supports 300 mA per diode continuously, with both diodes operating in parallel. Total forward current capability is 600 mA only if thermal design maintains T_j ≤ 150 °C - requiring proper copper pour under the thermal pad and ambient ≤ 85 °C. Derating applies per Figure 1 in the datasheet.

Is BAT30-07P6FILM suitable for automotive applications?

BAT30-07P6FILM is not qualified to AEC-Q101 and lacks automotive-specific qualification data. While its 150 °C T_j(max) and robust construction support under-hood ambient temperatures, ST does not specify it for automotive safety-critical systems. Use only in non-safety automotive subsystems with full user responsibility for validation.
