BZT52B5V1-HE3-08

Single Zener Diodes Overview

The BZT52B5V1-HE3-08 is a silicon planar Zener diode from Vishay Semiconductors, housed in an SOD-123 surface-mount package. It provides a nominal Zener voltage of 5.1 V with a tight tolerance of ±2%. The device is AEC-Q101 qualified for automotive applications and features a maximum power dissipation of 500 mW at ambient temperature. Electrical characteristics include a test current of 5 mA, a reverse leakage current of 100 nA, and a dynamic resistance of 60 Ohms.

Single Zener Diodes Feature Summary

• AEC-Q101 qualified for automotive reliability standards
• Silicon planar construction for stable regulation
• ESD protection exceeding 8 kV (HBM) and 800 V (MM)
• RoHS-compliant commercial grade material

Single Zener Diodes Applications

• General voltage reference circuits
• Over-voltage protection stages
• Voltage clamping applications

Single Zener Diodes Procurement Notes

Verify the specific HE3_A suffix confirms AEC-Q101 qualification status. Confirm the -08 tape and reel packaging format matches automated assembly requirements. Ensure the component meets RoHS compliance definitions as specified in the manufacturer's documentation before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation within a narrow tolerance band is required. The SOD-123 package offers a compact footprint suitable for high-density circuit designs. Consider the thermal resistance parameters if operating near maximum power dissipation limits or in elevated temperature environments.

Single Zener Diodes Part Context

This part belongs to the BZT52 series of small signal Zener diodes manufactured by Vishay. The series utilizes silicon planar technology and covers a wide range of Zener voltages graded according to the E24 standard. The BZT52B variant specifically denotes the tighter 2% tolerance option within the lineup.

Single Zener Diodes Replacement Considerations

Cross-reference other Vishay BZT52B5V1 variants such as BZT52B5V1-E3-08 for non-automotive grades. Verify that substitute components maintain identical Zener voltage, tolerance, and package dimensions to ensure mechanical and electrical compatibility.
