BZB784-C13-QX

Overview

The Nexperia BZB784-C13-QX is a voltage regulator double diode housed in an SOT323 (SC-70) surface-mount package. It features a nominal working voltage of 13 V with a ±5% tolerance range spanning 12.4 V to 14.1 V at a test current of 5 mA. The device has a maximum reverse leakage current of 100 nA at 8 V and a differential resistance of 170 Ω. Total power dissipation is rated at 350 mW for dual-diode loading. It operates within a junction temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards.

Feature Summary

• Dual common-anode configuration providing two independent Zener diodes in a compact SC-70 footprint.
• Automotive-grade qualification compliant with AEC-Q101 stress test requirements.
• Low forward voltage drop characteristic suitable for efficient signal clamping applications.

Applications

• General voltage regulation functions
• Electrostatic discharge (ESD) protection circuits
• Surge protection in automotive electronics

Procurement Notes

Verify the specific suffix 'X' against the official Nexperia ordering information table, as the datasheet lists standard '-Q' variants. Confirm that the marking code '9K' corresponds to the intended part number variant before finalizing procurement orders to ensure correct electrical specifications.

Selection Notes

Select this component when a dual Zener solution is required in space-constrained designs. The SOT323 package offers a small body size of 2 mm by 1.25 mm. Ensure the operating current remains within limits to maintain the specified 5% voltage tolerance and thermal performance under ambient conditions up to 150 °C.

Part Context

This part belongs to the BZB784-Q series, which provides low-power voltage regulation in ultra-small packages. The series covers nominal voltages from 2.4 V to 15 V, offering designers flexibility for various reference and protection needs while maintaining automotive reliability standards through standardized qualification processes.

Replacement Considerations

Direct substitutes include other BZB784-Q series parts with identical pinouts but different voltage ratings, such as BZB784-C12-Q or BZB784-C15-Q. Non-series equivalents like BZX84 or BZX384 require careful evaluation of package dimensions and power dissipation capabilities.
