Diodes Incorporated BZX84C13TS-7-F

Overview

BZX84C13TS-7-F from Diodes Incorporated is a triple-surface-mount Zener diode array with three isolated 13 V Zener elements in a single SOT-363 package, rated for 200 mW total power dissipation, 13.0 V nominal Zener voltage (min 12.4 V, max 14.1 V at 5 mA), and 30 Ω maximum Zener impedance at test current - used for precision voltage regulation and overvoltage protection in compact DC power rails.

For engineers reviewing the BZX84C13TS-7-F datasheet, BZX84C13TS-7-F pinout, BZX84C13TS-7-F application, or BZX84C13TS-7-F equivalent, key selection criteria include Zener voltage tolerance (±4.6%), thermal resistance (625 °C/W), reverse leakage (≤0.1 µA at 8.0 V), temperature coefficient (+7.0 to +11.0 mV/°C), and triple-diode isolation in ultra-small footprint.

Technical Context

This device integrates three electrically independent Zener diodes in a monolithic SOT-363 package, each with identical 13 V regulation characteristics. It operates within -65 °C to +150 °C ambient range and maintains stable breakdown behavior under pulsed conditions per short-duration test methodology.

The Zener voltage is specified at I_ZT = 5 mA with ±4.6% tolerance, and exhibits a positive temperature coefficient of +7.0 to +11.0 mV/°C - enabling predictable drift compensation in bias networks and reference circuits where thermal stability is critical.

Key Specifications

Pinout & Package

FAQ

What is the maximum continuous Zener current for BZX84C13TS-7-F?

The device is rated for 200 mW total power dissipation at 25 °C ambient. At 13 V Zener voltage, this corresponds to a maximum average current of ~15.4 mA per diode if all three operate simultaneously - but derating per Figure 1 reduces usable current to ~9.2 mA at 70 °C ambient due to 625 °C/W thermal resistance.

Can BZX84C13TS-7-F be used for bidirectional ESD protection?

No - it is a unidirectional Zener diode array. Each element conducts only in reverse breakdown (cathode-to-anode) and forward conduction (~0.9 V). For bidirectional ESD clamping, external series diodes or dedicated TVS arrays like D3V3M1U2SOT-7-F are required.

How does the temperature coefficient affect regulation accuracy over temperature?

With a +7.0 to +11.0 mV/°C coefficient, the Zener voltage increases by 0.7–1.1 V over a 100 °C junction rise. In a 25–125 °C operating range, regulation shifts by +0.7–1.1 V - requiring design margin or compensation in precision references, but acceptable for general-purpose clamping.

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

Yes - rated for Moisture Sensitivity Level 1 per J-STD-020D, meaning it can be stored indefinitely at ≤30 °C/60% RH and processed using standard Pb-free reflow profiles (peak 260 °C, 30 sec max) without baking or special handling.
