Nexperia USA Inc. BZV55-C62,135

Overview

BZV55-C62,135 from Nexperia is a ±5 % tolerance silicon Zener voltage regulator diode in a hermetically sealed SOD80C glass SMD package, rated for 62 V nominal working voltage at 5 mA test current, 400 mW total power dissipation at T_amb ≤ 50 °C, and 40 W non-repetitive peak reverse power (t_p = 100 µs). It delivers low differential resistance (120 Ω typ. at I_Z = 2 mA) and operates across −65 °C to +200 °C junction temperature range, commonly used for precision voltage reference and overvoltage clamping in power supply feedback paths.

For engineers reviewing the BZV55-C62,135 datasheet, BZV55-C62,135 pinout, BZV55-C62,135 application, or BZV55-C62,135 equivalent, key selection criteria include its 62 V Zener voltage tolerance (±5 %), thermal resistance (R_th(j-a) = 380 K/W), reverse leakage (≤3 µA at V_R = 58 V), differential resistance (120 Ω typ.), and SOD80C package footprint compatibility with reflow soldering per IPC-7095.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable DC reference voltage under varying load and line conditions. Its 62 V nominal Zener voltage is specified at I_Z = 2 mA, with temperature coefficient of +0.4 mV/K (typ.) and differential resistance of 120 Ω (typ.) enabling predictable regulation in low-power analog circuits.

The device uses a planar epitaxial construction with hermetic glass encapsulation, ensuring long-term stability and low noise performance. Its SOD80C package provides mechanical robustness and thermal performance suitable for board-level surge suppression and voltage clamping where transient immunity and compact size are critical.

FAQ

What is the maximum continuous forward current for BZV55-C62,135?

The device is not rated for continuous forward conduction; its absolute maximum forward current is 250 mA per limiting values table, but it is designed for reverse-bias Zener operation. Forward voltage is specified at 0.9 V max at 10 mA, and sustained forward bias risks thermal runaway due to lack of current-limiting structure.

Can BZV55-C62,135 be used in place of a 6.2 V Zener diode?

No-BZV55-C62,135 is a 62 V Zener diode, not 6.2 V. The "62" in the part number denotes nominal Zener voltage in volts. Substituting it for a 6.2 V device would result in catastrophic failure of downstream circuitry due to excessive clamping voltage and insufficient current regulation.

Does this diode require a heatsink for 400 mW operation?

No external heatsink is required for 400 mW operation at T_amb ≤ 50 °C, as the SOD80C package's thermal resistance (380 K/W) results in ~152 °C junction-to-ambient rise, remaining within the −65 °C to +200 °C rating. However, PCB copper area ≥ 25 mm² per pad is recommended to sustain this power level reliably.

How does the ±5 % tolerance affect regulation accuracy in feedback loops?

The ±5 % tolerance means actual V_Z falls between 58.9 V and 65.1 V at I_Z = 2 mA. In closed-loop feedback, this directly sets the worst-case output voltage error band; for example, a 12 V output derived via resistive divider from 62 V reference will vary by ±0.6 V if divider ratio is fixed, requiring design margin or post-assembly calibration.
