Diodes Incorporated BZX84C2V4TS-7-F

Overview

BZX84C2V4TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 2.4 V Zener elements in a single SOT-363 package, rated for 200 mW power dissipation, 5 mA test current, and ±0.2 V zener voltage tolerance at 25°C - used for precision voltage reference and overvoltage protection in compact DC power rails.

For engineers reviewing the BZX84C2V4TS-7-F datasheet, BZX84C2V4TS-7-F pinout, BZX84C2V4TS-7-F application, or BZX84C2V4TS-7-F equivalent, key selection criteria include zener voltage accuracy (2.2–2.6 V), low dynamic impedance (100 Ω @ 5 mA), thermal resistance (625 °C/W), and triple-diode integration for space-constrained biasing and clamping circuits.

Technical Context

This device integrates three electrically isolated Zener diodes in one ultra-small SOT-363 package, enabling independent voltage regulation or clamping on multiple signal lines without cross-coupling. Each element operates with a nominal 2.4 V breakdown at 5 mA, with temperature coefficient ranging from –3.5 to 0 mV/°C.

The array supports bidirectional transient suppression and precision DC biasing due to its low reverse leakage (50 µA @ 1.0 V) and stable zener impedance (100 Ω typical, 600 Ω max). It is qualified for operation from –65°C to +150°C and rated for 200 mW total power dissipation on FR4 PCBs with recommended pad layout.

FAQ

What is the maximum reverse voltage this device can withstand before breakdown?

The BZX84C2V4TS-7-F has a nominal zener voltage of 2.4 V with a guaranteed breakdown range of 2.2 V to 2.6 V at 5 mA test current. Its absolute maximum reverse voltage is not defined beyond this range, but it reliably clamps at ≤2.6 V under specified conditions. Operation above 2.6 V risks exceeding its 200 mW power rating unless current is strictly limited.

Can this device be used for bidirectional ESD protection?

Yes - each Zener element functions bidirectionally when paired with a series resistor: forward conduction occurs at ~0.9 V (VF), and reverse breakdown at 2.4 V. This dual-threshold behavior makes it suitable for I/O line clamping against both positive and negative transients, provided peak pulse energy stays within the device's derated power envelope.

Is the SOT-363 package compatible with standard reflow profiles?

Yes - the SOT-363 package is qualified for lead-free reflow per J-STD-020D Level 1 moisture sensitivity. It supports peak temperatures up to 260°C and is compatible with standard Pb-free solder profiles. The matte tin finish on Alloy 42 leads ensures reliable wetting and intermetallic formation during reflow.

How does temperature affect the zener voltage accuracy?

The temperature coefficient ranges from –3.5 to 0 mV/°C at 5 mA, meaning the zener voltage decreases slightly with rising temperature. Over –65°C to +150°C, total drift is bounded by the initial tolerance (±0.2 V) plus coefficient-induced shift - typically within ±0.3 V across full range, verified in production testing per DS30187 Rev. 11.
