Nexperia USA Inc. TDZ5V6JF

Overview

TDZ5V6JF from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation and overvoltage protection in space-constrained PCBs. 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 at 0.5 mA, and AEC-Q101 qualification for automotive use.

For engineers reviewing the TDZ5V6JF datasheet, TDZ5V6JF pinout, TDZ5V6JF application, or TDZ5V6JF equivalent, key selection criteria include its 5.6 V regulation accuracy, low 275 pF capacitance at 0 V, −1.7 to +2.8 mV/K temperature coefficient, and suitability for ESD clamp circuits, power rail stabilization, and automotive body control modules.

Technical Context

This Zener operates as a two-terminal voltage reference device, conducting in reverse breakdown when cathode-to-anode voltage exceeds its specified V_Z. Its thermal resistance from junction to solder point is 25 K/W, enabling reliable operation up to 150 °C junction temperature under defined PCB mounting conditions.

The device exhibits a negative-to-positive temperature coefficient crossing near 5.6 V, resulting in stable regulation across −55 °C to +150 °C ambient. Its non-repetitive peak reverse power dissipation is rated at 180 W for pulses ≤100 μs, supporting transient surge suppression in low-energy clamping applications.

Key Specifications

Pinout & Package

SOD323F (SC-90) is a 2-pin surface-mount plastic package measuring 2.7 × 1.6 × 0.95 mm, with cathode marked by a bar on the top surface. Mounting requires reflow only, using a defined footprint with 0.5 mm pad width and 0.6 mm solder land spacing.

FAQ

What is the maximum continuous forward current rating for TDZ5V6JF?

The TDZ5V6JF is not rated for continuous forward conduction; its absolute maximum forward current is 250 mA per pulse test conditions (tp ≤ 100 μs). In normal Zener operation, it functions in reverse bias only-forward voltage is specified at 1.1 V @ 100 mA for verification, not sustained operation.

Can TDZ5V6JF be used as a replacement for a 5.1 V Zener in an existing design?

No-TDZ5V6JF has a nominal Zener voltage of 5.6 V (5.20–6.00 V range), not 5.1 V. Substituting it would raise the regulated voltage by ~0.5 V, potentially exceeding MCU I/O tolerances or LDO feedback thresholds. 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 solder point-comparable to many through-hole packages-but relies entirely on PCB copper for heat spreading. Unlike DO-35, it lacks leads for heatsinking; thermal performance degrades rapidly without ≥16 mm² cathode pad area and proper reflow profile.

Is TDZ5V6JF suitable for bidirectional ESD protection?

No-TDZ5V6JF is a unidirectional Zener diode with cathode/anode polarity. For bidirectional ESD protection (e.g., USB data lines), a symmetric device like a TVS array (e.g., PESD5V0S1BA) is required. TDZ5V6JF can only clamp positive transients relative to ground when cathode is biased above anode.
