Diodes Incorporated BZX84C5V6TS-7-F

Overview

BZX84C5V6TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 5.6 V Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 40 Ω dynamic impedance at 5 mA, and reverse current ≤1.0 µA at 2.0 V, used for precision voltage regulation and overvoltage protection in compact power management circuits.

For engineers reviewing the BZX84C5V6TS-7-F datasheet, BZX84C5V6TS-7-F pinout, BZX84C5V6TS-7-F application, or BZX84C5V6TS-7-F equivalent, key selection criteria include nominal Zener voltage (5.6 V), Zener impedance (40 Ω @ 5 mA), thermal resistance (625 °C/W), and triple-diode isolation in ultra-small SOT-363 footprint for space-constrained biasing and clamping designs.

Technical Context

This device integrates three independent Zener diodes sharing only mechanical packaging-no internal electrical connection-enabling simultaneous regulation of multiple low-current rails or redundant reference paths. Each element exhibits tight 5.2–6.0 V Zener voltage tolerance at 5 mA test current and temperature coefficient of –2.0 to +2.5 mV/°C.

Designed for surface-mount assembly on FR4 PCBs with specified pad layout, it operates across –65 °C to +150 °C and derates linearly above 25 °C ambient per the 200 mW maximum power curve. Reverse leakage remains ≤1.0 µA up to 2.0 V, supporting stable reference generation in low-power sensor interfaces.

FAQ

What is the maximum continuous Zener current for BZX84C5V6TS-7-F?

The device is rated for 200 mW total power dissipation at 25 °C ambient. At nominal 5.6 V Zener voltage, this corresponds to a maximum average current of approximately 35.7 mA (200 mW ÷ 5.6 V). Derating applies above 25 °C per the published power derating curve, limiting usable current in elevated ambient conditions.

Can BZX84C5V6TS-7-F be used as a bidirectional ESD clamp?

No-it is a unidirectional Zener diode array. Each element conducts only in reverse breakdown (cathode positive relative to anode). For bidirectional ESD protection, external series diodes or dedicated TVS arrays like the D3V3Z5U-7-F are required. Its primary role is precision DC voltage regulation and overvoltage clamping in one polarity.

How does the SOT-363 package affect thermal performance compared to SOT-23?

The SOT-363 has higher thermal resistance (625 °C/W vs. ~417 °C/W for SOT-23) due to smaller die attach area and longer thermal path through shared leadframe. This necessitates conservative power derating above 25 °C ambient and limits peak pulse handling. However, its triple-element integration offsets this by eliminating interconnect losses and layout-induced thermal coupling between discrete devices.

Is the marking code KR3 verified for BZX84C5V6TS-7-F?

Yes-per Diodes Incorporated's DS30187 Rev. 11 datasheet, "KR3" is the official top-side marking code for the BZX84C5V6TS variant. The "-7-F" suffix denotes SOT-363 packaging in 3,000-piece tape-and-reel format with lead-free plating, consistent with Diodes' standard ordering nomenclature and RoHS compliance documentation.
