Diodes Incorporated BZX84C2V7TS-7-F

Overview

BZX84C2V7TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 2.7 V ±0.2 V Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 625 °C/W thermal resistance, and operating across –65 °C to +150 °C - used for precision voltage clamping and reference in low-power analog sensor signal conditioning circuits.

For engineers reviewing the BZX84C2V7TS-7-F datasheet, BZX84C2V7TS-7-F pinout, BZX84C2V7TS-7-F application, or BZX84C2V7TS-7-F equivalent, key selection criteria include nominal Zener voltage (2.7 V), Zener impedance (≤100 Ω at 5 mA), reverse current (≤20 µA at 1.0 V), temperature coefficient (–3.5 to 0 mV/°C), and triple-diode isolation in ultra-small SOT-363.

Technical Context

This device integrates three electrically isolated Zener diodes sharing only mechanical packaging - no internal connection between anodes or cathodes. Each diode exhibits sharp reverse breakdown at 2.7 V with tight tolerance (2.5–2.9 V), low dynamic impedance (≤100 Ω at I_ZT = 5 mA), and minimal temperature drift (–3.5 to 0 mV/°C).

Designed for surface-mount operation on FR4 PCBs with specified pad layout, it supports stable voltage regulation under pulsed conditions (short-duration test per Note 5) and maintains ≤20 µA leakage at 1.0 V reverse bias - critical for battery-powered rail monitoring and ESD-protected I/O clamping.

FAQ

What is the maximum continuous Zener current for BZX84C2V7TS-7-F at 25°C?

The device is rated for 200 mW total power dissipation. At its nominal 2.7 V Zener voltage, this corresponds to a maximum continuous Zener current of approximately 74 mA (200 mW ÷ 2.7 V). Derating applies above 25°C per the published power derating curve - at 70°C ambient, max current drops to ~44 mA.

Can BZX84C2V7TS-7-F be used for bidirectional TVS protection?

No - it is a unidirectional Zener diode array. Each element conducts only in reverse breakdown (cathode positive relative to anode). For bidirectional protection, two devices must be connected anode-to-anode or cathode-to-cathode, or a dedicated bidirectional TVS like SMBJ2.7A should be used instead.

How does the SOT-363 pinout differ from standard SOT-23 for Zener diodes?

SOT-363 has six terminals (A1/C1/A2/C2/A3/C3) supporting three isolated diodes, whereas SOT-23 has only three pins (anode/cathode/common). The SOT-363 layout places anodes on one row and cathodes on the opposite row - confirmed by Diodes Inc. DS30187 Figure "Top View Package Pin Out Configuration" - enabling true independent routing.

Is the temperature coefficient of –3.5 to 0 mV/°C measured per diode or averaged across all three?

The specification applies individually to each of the three Zener elements. Diodes Incorporated characterizes all units in the BZX84C2V7TS-7-F lot to ensure each diode meets the full –3.5 to 0 mV/°C range at I_ZT = 5 mA, as verified in the Electrical Characteristics table on page 2 of DS30187 Rev. 11–2.
