Nexperia USA Inc. TDZ5V6J/ZLX

Overview

TDZ5V6J/ZLX from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and transient suppression in low-power circuits. It delivers a nominal Zener voltage of 5.6 V at 10 mA, with ±4% tolerance (5.20–6.00 V), 400 Ω differential resistance, and AEC-Q101 qualification for automotive use.

For engineers reviewing the TDZ5V6J/ZLX datasheet, TDZ5V6J/ZLX pinout, TDZ5V6J/ZLX application, or TDZ5V6J/ZLX equivalent, this device serves as a compact, thermally robust voltage reference in power supply feedback loops, overvoltage clamping, and ESD protection circuits where tight voltage stability and small footprint are critical.

Technical Context

The TDZ5V6J/ZLX operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable output voltage under varying load and temperature conditions. Its Zener voltage exhibits a temperature coefficient of −1.7 to +2.8 mV/K, enabling predictable drift behavior across −55 °C to +150 °C ambient range.

It supports pulsed non-repetitive peak reverse power dissipation up to 180 W (tp ≤ 100 μs), while maintaining continuous total power dissipation of 500 mW at Tamb ≤ 25 °C. Thermal resistance from junction to solder point is 25 K/W, confirming efficient heat transfer to PCB copper pads.

FAQ

What is the maximum continuous forward current rating for TDZ5V6J/ZLX?

The TDZ5V6J/ZLX is a Zener diode intended for reverse-bias operation; its forward current rating is specified only for characterization. Per datasheet Table 5, the absolute maximum forward current is 250 mA, but typical forward voltage is 1.1 V at 100 mA. Forward conduction is not a functional operating mode in regulation applications.

Can TDZ5V6J/ZLX be used as a replacement for a 5.1 V Zener in an existing design?

No-TDZ5V6J/ZLX has a nominal Zener voltage of 5.6 V (5.20–6.00 V), not 5.1 V. Substituting it for a 5.1 V device would raise the regulated voltage by ~0.5 V, potentially exceeding downstream IC absolute maximum ratings. Use TDZ5V1J (5.00–5.20 V) instead for 5.1 V applications.

How does the SOD323F package affect thermal performance compared to larger packages like DO-35?

The SOD323F package achieves R_th(j-sp) = 25 K/W to the cathode solder pad-comparable to many DO-35 parts mounted on large copper areas-due to optimized internal die attach and direct thermal path through the cathode terminal. However, its R_th(j-a) = 250 K/W in free air is significantly higher than DO-35 (~300–400 K/W), meaning board-level copper thermal relief is essential for full 500 mW utilization.

Is TDZ5V6J/ZLX suitable for bidirectional ESD protection?

No-it is a unidirectional Zener diode with defined anode/cathode polarity. For bidirectional ESD protection, a symmetric TVS diode (e.g., PESD5V0S1BA) or back-to-back Zener pair is required. TDZ5V6J/ZLX provides only unidirectional clamping from cathode to anode during positive transients relative to ground.
