Nexperia USA Inc. BZT52H-B7V5,115

Overview

BZT52H-B7V5,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD123F package, rated for 7.5 V nominal breakdown voltage at 5 mA, 830 mW total power dissipation, and 150 °C maximum junction temperature-used for precision voltage reference and overvoltage protection in low-power analog supply rails.

For engineers reviewing the BZT52H-B7V5,115 datasheet, BZT52H-B7V5,115 pinout, BZT52H-B7V5,115 application, or BZT52H-B7V5,115 equivalent, this page delivers verified Zener parameters, thermal resistance (70 K/W to solder point), differential resistance (80 Ω max), reverse current (1 μA max at 5.7 V), and temperature coefficient (2.5–5.3 mV/K) critical for stable biasing and clamping design.

Technical Context

This Zener diode operates in reverse-bias breakdown mode with tightly controlled V_Z = 7.35 V to 7.65 V (±2 %) at I_Z = 5 mA, exhibiting low dynamic impedance (≤80 Ω) and predictable temperature drift (2.5–5.3 mV/K). Its SOD123F package enables surface-mount integration on FR4 PCBs with defined thermal pad layout.

It supports pulsed operation up to 40 W non-repetitive peak reverse power (t_p = 100 μs) and maintains stable regulation under ambient temperatures from –65 °C to +150 °C, with thermal resistance from junction to solder point at 70 K/W when mounted per specification.

FAQ

What is the maximum continuous reverse current this Zener can handle at 7.5 V?

The BZT52H-B7V5,115 is not rated for continuous reverse current at its nominal Zener voltage-it operates in breakdown with current determined by external series resistance. Its absolute maximum forward current is 250 mA, but Zener bias current must stay within power limits: at 7.5 V, maximum continuous I_Z ≈ 110 mA (830 mW ÷ 7.5 V), derated per ambient temperature and PCB thermal design.

Can this diode replace a 7.5 V Zener with ±5 % tolerance in an existing design?

Yes-BZT52H-B7V5,115 fits the same SOD123F footprint and offers tighter ±2 % tolerance (7.35–7.65 V vs. 7.13–7.88 V), lower dynamic impedance (≤80 Ω vs. ≤100 Ω), and higher power rating (830 mW vs. typically 500 mW). No layout change is needed, and performance improves in regulation accuracy and thermal margin.

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

At I_Z = 5 mA, the BZT52H-B7V5,115 exhibits a temperature coefficient of 2.5–5.3 mV/K, meaning V_Z increases by ~0.3–0.65 V across that 165 K range. This results in total V_Z shift of approximately ±0.5 V, which must be accounted for in precision references but remains acceptable for clamping and coarse biasing.

Is this part qualified for automotive applications?

No-BZT52H-B7V5,115 is explicitly designated as non-automotive qualified per Nexperia's revision history (Rev. 7, Jan 2023). It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation.
