Nexperia USA Inc. TDZ3V6J,115

Overview

TDZ3V6J,115 from Nexperia is a single Zener diode in SOD323F (SC-90) package, designed for precision voltage regulation at 3.6 V nominal Zener voltage with ±0.14 V tolerance (3.53–3.67 V), 500 mW total power dissipation, and AEC-Q101 qualification for automotive use in ECU power rail clamping and sensor reference circuits.

For engineers reviewing the TDZ3V6J,115 datasheet, TDZ3V6J,115 pinout, TDZ3V6J,115 application, or TDZ3V6J,115 equivalent, key selection criteria include Zener voltage accuracy at 5 mA, differential resistance of 500 Ω, low reverse leakage (≤5 µA at 2.8 V), thermal resistance to solder point (25 K/W), and suitability for space-constrained SMT designs requiring automotive-grade reliability.

Technical Context

This Zener diode operates as a two-terminal voltage reference device, maintaining stable reverse breakdown at 3.6 V under regulated current conditions. Its junction temperature range spans −55 °C to +150 °C, and it exhibits a negative temperature coefficient of −3.5 mV/K, enabling predictable drift compensation in bias networks.

The device uses planar epitaxial construction for low noise and repeatable breakdown characteristics. It supports non-repetitive surge handling up to 180 W (tp ≤ 100 µs), and its 25 K/W junction-to-solder-point thermal resistance enables effective heat transfer on FR4 PCBs with 16 mm² cathode pad area.

FAQ

What is the maximum continuous forward current rating for TDZ3V6J,115?

The absolute maximum forward current is 250 mA per Table 5 of the datasheet. However, sustained operation above 100 mA is discouraged due to thermal limitations-forward voltage reaches 1.1 V at 100 mA, generating 110 mW dissipation that exceeds safe margins without forced cooling or large copper areas.

Can TDZ3V6J,115 be used as a replacement for a 3.3 V Zener diode in a voltage reference circuit?

No-it is specified for 3.6 V nominal Zener voltage (3.53–3.67 V at 5 mA), not 3.3 V. Using it in place of a 3.3 V device would raise the reference level by ~300 mV, potentially violating ADC input ranges or comparator thresholds. The TDZ3V3J variant is the correct 3.3 V option in this series.

How does the −3.5 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?

Over that 165 K range, the Zener voltage shifts by approximately −578 mV (−3.5 mV/K × 165 K), resulting in a final value near 3.02 V at +125 °C. This drift must be compensated in precision references using complementary components or calibration; it is acceptable for non-critical clamping where absolute accuracy is secondary to functional robustness.

Is reflow soldering the only recommended assembly method for TDZ3V6J,115?

Yes-the datasheet explicitly states "Reflow soldering is the only recommended soldering method" (Section 11). Wave or hand soldering risks exceeding the 260 °C peak temperature limit and damaging the internal junction or package integrity, especially given the thin leadframe and small die size inherent to SOD323F construction.
