Nexperia USA Inc. BZV55-B13,115

Overview

BZV55-B13,115 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 13 V nominal working voltage with ±2 % tolerance (B-series), 50 Ω typical differential resistance at I_Z = 5 mA, and 100 nA reverse current at V_R = 8 V. It delivers stable reference voltage in low-current bias networks for power supply feedback, sensor excitation, and overvoltage clamping in industrial control modules.

For engineers reviewing the BZV55-B13,115 datasheet, BZV55-B13,115 pinout, BZV55-B13,115 application, or BZV55-B13,115 equivalent, this page provides verified electrical parameters, thermal behavior under surge conditions, SOD80C footprint compatibility, and validated alternative parts for precision voltage reference design.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable 13 V reference across load variations, with temperature coefficient of +7.0 mV/K at I_Z = 5 mA and junction-to-ambient thermal resistance of 380 K/W in free air. Its low 500 mW total power dissipation rating requires careful thermal management on PCBs with limited copper area.

The device exhibits non-repetitive peak reverse power dissipation of 40 W for 100 µs square-wave pulses at T_j = 25 °C, and diode capacitance of 80 pF at 1 MHz and 0 V reverse bias - critical for high-frequency noise suppression and transient response in analog signal chains.

FAQ

What is the maximum continuous forward current for BZV55-B13,115?

The absolute maximum forward current is 250 mA per datasheet Table 5. However, sustained forward conduction is not intended in normal Zener operation; the device is designed for reverse-bias regulation. Forward voltage is specified at 10 mA (≤0.9 V), and prolonged forward bias above 100 mA risks thermal runaway due to low thermal resistance.

Can BZV55-B13,115 be used in place of a 12 V Zener diode?

No - BZV55-B13,115 is strictly a 13 V nominal device (12.7–13.3 V range). Substituting it for a 12 V part introduces ≥8.3 % overvoltage in regulation, potentially damaging downstream circuitry. For 12 V reference, use BZV55-B12,115 (11.8–12.2 V) or BZX55C12.

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

At I_Z = 5 mA, the temperature coefficient is +7.0 mV/K (Table 8). Over a 165 K range, this causes up to ±578 mV drift (±4.5 % of 13 V), requiring compensation in wide-temperature applications. For improved stability, operate at I_Z = 1 mA where SZ drops to +6.0 mV/K, or pair with NTC thermistors.

Is the SOD80C package compatible with standard reflow soldering profiles?

Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C footprint (Fig 7) uses 2.30 mm × 4.30 mm solder lands with 0.90 mm spacing. Peak temperature must not exceed 260 °C for ≤10 seconds; thermal resistance data assumes mounting on 10 × 10 × 0.6 mm ceramic substrate.
