Nexperia USA Inc. BZV55-B5V6,135

Overview

BZV55-B5V6,135 from Nexperia is a low-power Zener voltage regulator diode in a hermetically sealed glass SOD80C surface-mount package, rated for 5.6 V nominal regulation at 5 mA with ±2 % tolerance, 80 Ω typical differential resistance, and −2.0 mV/K temperature coefficient. It delivers stable reference voltage in low-current bias networks and power rail clamping circuits for industrial sensor interfaces and microcontroller reset supervision.

For engineers reviewing the BZV55-B5V6,135 datasheet, BZV55-B5V6,135 pinout, BZV55-B5V6,135 application, or BZV55-B5V6,135 equivalent, this page provides verified electrical parameters, thermal behavior under transient surge (40 W, 100 µs), reverse leakage (≤1 µA at VR = 2 V), forward voltage (≤0.9 V @ 10 mA), and SOD80C footprint compatibility for PCB layout validation.

Technical Context

This Zener diode operates in reverse breakdown to maintain a precise DC reference voltage across its terminals under varying load and temperature conditions. Its −2.0 mV/K temperature coefficient ensures minimal drift over −65 °C to +200 °C junction range, and its 80 Ω differential resistance enables stable regulation even with modest current variations (±1 mA around 5 mA).

The device is optimized for low-power, non-repetitive surge environments: it supports up to 40 W non-repetitive peak reverse power dissipation (tp = 100 µs square wave) and 500 mW total power dissipation on ceramic substrate, with thermal resistance from junction to solder point at 300 K/W.

FAQ

What is the maximum continuous reverse current for reliable regulation?

The BZV55-B5V6,135 is rated for 5 mA nominal Zener test current, with absolute maximum continuous reverse current limited by power dissipation: at 5.6 V, sustained operation above ~89 mA exceeds 500 mW on ceramic substrate. For stable regulation, recommended operating range is 1–20 mA, balancing rdif, TC, and self-heating.

Can this diode be used in forward-bias mode as a low-VF clamp?

Yes-the device exhibits ≤0.9 V forward voltage at 10 mA, making it suitable for polarity protection or low-drop clamping in bidirectional signal paths. However, its primary design intent and characterized performance (e.g., rdif, TC) are specified in reverse breakdown; forward characteristics are secondary and not guaranteed beyond the stated max VF.

How does the −2.0 mV/K temperature coefficient impact circuit accuracy?

At 5.6 V nominal, −2.0 mV/K translates to −0.036 %/°C drift. Over a 100 °C range (−40 °C to +60 °C), this yields ~−0.36 % total shift. In precision applications, this must be included in system error budgets-especially where uncalibrated operation across temperature is required.

Is the SOD80C package compatible with standard reflow profiles?

Yes-Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The SOD80C outline (3.3–3.7 mm × 1.45–1.60 mm) uses standard 2.30 mm × 4.30 mm reflow footprint per Figure 7, with 0.90 mm solder lands. Glass body withstands peak temperatures up to 260 °C for ≤30 seconds without cracking or parameter shift.
