DZ4J160K0R

Overview

The DZ4J160K0R is a dual silicon epitaxial planar Zener diode manufactured by Panasonic. It provides a nominal Zener voltage of 16.8 V with a tolerance range of 15.3 V to 18.0 V at a test current of 5 mA. The device features a low Zener operating resistance of 50 Ω and a temperature coefficient of 14.2 mV/°C. Rated for a total power dissipation of 200 mW, it operates within an ambient temperature range of -40 °C to +85 °C and supports junction temperatures up to 150 °C. Packaged in the SMini4-F3-B (JEITA SC-113BB) surface-mount format measuring 2.1 mm x 2.0 mm x 0.7 mm, it is supplied in reels of 3,000 units.

Feature Summary

• Dual configuration providing two independent Zener elements in a compact footprint
• Low Zener operating resistance for stable voltage regulation
• Excellent rising characteristics of Zener current in low-current ranges
• Halogen-free construction compliant with RoHS directives

Applications

• Constant voltage reference circuits
• Surge absorption applications
• Waveform clipping circuits

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the marking symbol XJ matches the specific batch requirements. Ensure storage conditions adhere to moisture sensitivity level guidelines prior to assembly. Validate compliance with environmental directives relevant to the target market before final procurement decisions.

Selection Notes

Select this component when a dual Zener configuration is required in a minimal surface-mount area. The 200 mW power rating suits low-power signal conditioning tasks. Verify that the 16.8 V nominal voltage aligns with circuit design specifications. Consider the 50 Ω impedance for high-frequency noise filtering requirements.

Part Context

This part belongs to the DZ2J series of surface mount Zener diodes from Panasonic Industry. It utilizes the SMini4 package family, designed for automated pick-and-place assembly. The device represents a halogen-free alternative to older leaded packages while maintaining similar electrical performance profiles for general-purpose voltage regulation.

Replacement Considerations

Direct pin-compatible replacements are not explicitly documented in the provided datasheet. Evaluate other Panasonic dual Zener diodes within the SMini4 package family for potential substitution based on matching voltage and power dissipation ratings.
