Nexperia USA Inc. BZV85-C15,113

Overview

BZV85-C15,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 15 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at T_tp = 55 °C, and 60 W non-repetitive peak reverse power handling. It serves as a precision voltage reference or shunt regulator in low-to-medium current DC stabilization circuits, such as power supply feedback paths and sensor biasing networks.

For engineers reviewing the BZV85-C15,113 datasheet, BZV85-C15,113 pinout, BZV85-C15,113 application, or BZV85-C15,113 equivalent, key selection criteria include its 13.8–15.6 V Zener voltage range, 15 Ω typical differential resistance at 5 mA test current, −0.5 to +2.2 mV/K temperature coefficient, 10.5 µA max reverse leakage at 12 V, and suitability for PCB-mounted thermal management with 1 cm² copper per lead.

Technical Context

This Zener diode operates in reverse breakdown mode to maintain stable DC voltage across its terminals under varying load or input conditions. Its E24-standardized 15 V rating targets mid-range regulation needs where tighter tolerance than general-purpose Zeners is required but cost-sensitive designs preclude active references.

Thermal performance is defined by junction-to-tie-point resistance of 110 K/W (lead length 4 mm) and junction-to-ambient resistance of 175 K/W (lead length 10 mm), requiring PCB copper area management for sustained 1.3 W operation. The device exhibits a negative-to-positive temperature coefficient crossover near 5.1 V, and for the C15 variant, SZ is specified as +8.9 to +13.6 mV/K - indicating positive drift with temperature above 25 °C.

FAQ

What is the maximum continuous current this Zener can regulate at 15 V?

At 15 V, the maximum continuous Zener current is determined by power dissipation limits: 1.3 W ÷ 15 V ≈ 87 mA under T_tp = 55 °C conditions. Derating applies above that temperature - e.g., ~65 mA at 75 °C ambient with 1 cm² copper per lead. Exceeding this causes thermal runaway due to positive TC behavior.

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

With S_Z = +8.9 to +13.6 mV/K, the Zener voltage increases ~1.2 V to ~1.8 V across this 165 K range. For a 15 V nominal device, that represents +8 % to +12 % drift - requiring compensation (e.g., series NTC or complementary Zener) if better than ±2 % stability is needed over full temperature range.

Can this diode be used in AC signal clipping applications?

Yes - its 1 V forward voltage and symmetric reverse breakdown allow use in bidirectional clipping. However, the 15 V reverse threshold and 1.3 W power limit restrict it to low-frequency, low-energy signals (<10 kHz, <100 mW average). For precision clipping, matched dual-Zener configurations are preferred.

Is the SOD66 package compatible with automated through-hole assembly?

Yes - the SOD66 (DO-41) package has standard 25.4 mm lead spacing and tinned leads suitable for wave soldering and selective soldering processes. Lead diameter (0.5 mm) and body dimensions meet IPC-7351 Class L requirements, and the hermetic seal ensures reliability after reflow exposure up to 260 °C peak.
