Diodes Incorporated BZX84C7V5TS-7-F

Overview

BZX84C7V5TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 7.5 V (nominal) Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 15 Ω typical Zener impedance at 5 mA, and reverse current ≤1.0 µA at 5.0 V, used for precision voltage regulation and overvoltage protection in compact DC power rails.

For engineers reviewing the BZX84C7V5TS-7-F datasheet, BZX84C7V5TS-7-F pinout, BZX84C7V5TS-7-F application, or BZX84C7V5TS-7-F equivalent, key selection criteria include nominal Zener voltage tolerance (±0.5 V), low thermal resistance (625 °C/W), triple-diode isolation, RoHS-compliant matte tin plating, and SOT-363 footprint compatibility with high-density PCB layouts.

Technical Context

This device integrates three independent Zener diodes sharing only mechanical packaging-not electrical connection-enabling simultaneous regulation of multiple voltage nodes. Each element exhibits tight 7.0–7.9 V Zener voltage range at 5 mA test current, with temperature coefficient of +2.5 to +5.3 mV/°C.

It operates across –65 °C to +150 °C ambient, with derated power dissipation above 25 °C per Fig. 1, and maintains <1.0 µA reverse leakage at VR = 5.0 V, supporting low-power standby circuits and precision reference buffering.

FAQ

What is the maximum continuous power dissipation per Zener element in BZX84C7V5TS-7-F?

The device is rated for 200 mW total power dissipation across all three elements. Since the diodes are electrically isolated and share only thermal mass, each element may dissipate up to 200 mW individually if others are unbiased-but the absolute maximum junction temperature must still be observed. Derating begins at 25 °C ambient per Figure 1 in DS30187 Rev. 11-2.

Can BZX84C7V5TS-7-F be used in reverse-biased avalanche mode for ESD protection?

Yes-it is routinely applied as a low-capacitance (typ. 30 pF at 1 V) bidirectional clamp. Its 7.5 V nominal Zener voltage provides robust protection against transients exceeding 5.5 V on 5 V buses, with sub-µA leakage preserving signal integrity. However, it is not rated to IEC 61000-4-2 Level 4; supplemental TVS devices are recommended for certified ESD immunity.

How does the temperature coefficient affect regulation accuracy over –40 °C to +125 °C?

With a specified TC of +2.5 to +5.3 mV/°C at 5 mA, the Zener voltage shifts approximately +0.38 V to +0.82 V across that 165 °C span. For applications requiring <1% regulation stability, external compensation or tighter TC Zeners (e.g., BZX84C7V5E) should be considered-this part targets moderate-accuracy, cost-sensitive designs.

Is the SOT-363 pinout compatible with standard pick-and-place equipment?

Yes-the SOT-363 package conforms to JEDEC MO-178AB, with 0.65 mm pitch, coplanar leads, and defined orientation mark (see Diodes DS30187 page 3). It is supported by all major placement platforms including Fuji NXT, Yamaha YSM20, and Mycronic MYPro, with standard vision fiducials and vacuum nozzle profiles.
