Nexperia USA Inc. BZV90-C62,115

Overview

BZV90-C62,115 from Nexperia is a medium-power Zener voltage regulator diode in SOT223 package, designed for precision DC voltage reference and stabilization in power supply rails. It delivers a nominal working voltage of 62 V at 5 mA test current, with ±5% tolerance, 6 Ω typical differential resistance, and −0.3 mV/K temperature coefficient at 5 mA - enabling stable regulation in industrial power converters and automotive sensor interfaces.

For engineers reviewing the BZV90-C62,115 datasheet, BZV90-C62,115 pinout, BZV90-C62,115 application, or BZV90-C62,115 equivalent, key selection criteria include its 62 V Zener voltage, 1.5 W continuous power dissipation, SOT223 thermal performance (R_{th j-a} = 83.3 K/W), non-repetitive 40 W surge capability, and low reverse leakage (<0.05 μA at 43.4 V).

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable reference voltage across varying load and line conditions. Its design targets applications requiring tight voltage regulation without active feedback, leveraging low dynamic impedance (6 Ω typ.) and predictable temperature behavior (−0.3 mV/K) over 25–150 °C junction range.

The SOT223 package integrates an exposed collector pad for enhanced thermal conduction, supporting 1.5 W continuous dissipation on FR4 PCBs with 2 cm² copper area. The dual-cathode configuration (pins 2 and 4) enables flexible PCB layout while maintaining low-inductance reverse path integrity.

FAQ

What is the maximum continuous reverse current this Zener can handle at 62 V?

The BZV90-C62,115 does not specify a maximum continuous reverse current independent of power. At its rated 62 V Zener voltage, the absolute maximum continuous current is derived from P_tot = 1500 mW, yielding I_Zmax ≈ 24.2 mA (1500 mW ÷ 62 V). Operation above this level risks thermal runaway unless board-level heatsinking exceeds the specified 2 cm² copper area.

Can pins 2 and 4 be used independently for separate cathode paths?

No - pins 2 and 4 are internally shorted cathode terminals, not isolated nodes. They are provided to reduce parasitic inductance and improve current sharing during surge events. Using them as separate connections violates the internal construction and may cause uneven current distribution or localized overheating.

How does the −0.3 mV/K temperature coefficient affect regulation accuracy over temperature?

At 62 V nominal, a −0.3 mV/K coefficient translates to −0.0048 %/K drift. Over a 100 K range (−40 to +60 °C), total drift is approximately −0.48 %, or −0.3 V. This is within the ±5% initial tolerance band and remains stable without external compensation, making it suitable for applications where ±0.5% total regulation accuracy is acceptable.

Is this device qualified for automotive applications per AEC-Q101?

The BZV90-C62,115 is not AEC-Q101 qualified. While Nexperia offers AEC-Q101 Zener diodes (e.g., BZX84-A62), the BZV90 series is specified for industrial and general-purpose use. Its 150 °C maximum junction temperature and robust surge rating support automotive-adjacent applications, but formal qualification requires explicit AEC-Q101 test reports and part numbering.
