Nexperia USA Inc. BZV55-C13,135

Overview

BZV55-C13,135 from Nexperia is a ±5 % tolerance silicon Zener diode in a hermetically sealed SOD80C glass SMD package, rated for 13 V nominal Zener voltage at 5 mA test current, 500 mW total power dissipation, and 100 nA reverse leakage at 8 V. It delivers low differential resistance (≤170 Ω) and a temperature coefficient of +7.0 to +11.0 mV/K, enabling stable voltage reference in low-power analog sensing and supply rail clamping circuits.

For engineers reviewing the BZV55-C13,135 datasheet, BZV55-C13,135 pinout, BZV55-C13,135 application, or BZV55-C13,135 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (R_th(j-a) = 380 K/W), non-repetitive surge capability (40 W @ 100 µs), cathode-marked SOD80C footprint compatibility, and I_ZSM = 2.5 A peak reverse current.

Technical Context

This Zener diode operates in reverse breakdown to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its design targets precision regulation in low-current (<250 mA forward, <2.5 A pulsed reverse), low-power (<500 mW continuous) applications where hermetic sealing ensures long-term stability in humid or chemically active environments.

The device exhibits a positive temperature coefficient (+7.0 to +11.0 mV/K) and low junction capacitance (≤80 pF @ 1 MHz, 0 V), making it suitable for DC biasing and noise-sensitive analog signal conditioning rather than high-frequency voltage clamping. Its SOD80C package supports reflow and wave soldering per IPC-J-STD-020.

FAQ

What is the maximum continuous reverse current this diode can handle?

The BZV55-C13,135 does not specify a maximum continuous reverse (Zener) current; instead, its safe operating limit is defined by total power dissipation. At 13 V nominal Zener voltage, continuous Zener current must be limited to ≤38.5 mA to stay within the 500 mW rating at T_amb ≤ 50 °C. Derating is required above that ambient temperature per the R_th(j-a) = 380 K/W thermal resistance.

Can this Zener diode be used in series for higher voltage references?

Yes, multiple BZV55-C13,135 diodes may be connected in series to achieve higher reference voltages, but tolerance accumulates linearly (e.g., two units yield ±10 % overall). Thermal tracking between devices is not guaranteed, and differential resistance adds directly-so regulation accuracy degrades versus a single higher-voltage Zener. Use only when no suitable single-device alternative exists.

Is the SOD80C package compatible with lead-free reflow processes?

Yes, the SOD80C package is qualified for lead-free reflow soldering per IPC-J-STD-020. The recommended profile includes peak temperature ≤260 °C, time above liquidus 60–150 seconds, and ramp rates compliant with Class 3 assembly standards. The hermetic glass body withstands thermal shock without cracking or seal failure.

How does the temperature coefficient affect regulation in a 0–70 °C ambient range?

With a specified SZ of +7.0 to +11.0 mV/K, the BZV55-C13,135's Zener voltage increases by approximately 490–770 mV across a 70 °C rise. For applications requiring stable reference over temperature, this drift must be compensated in system-level calibration or mitigated via circuit techniques such as complementary transistor biasing or temperature-compensated reference ICs.
