Product details
Overview
BZV85-C68,113 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 68 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at Ttp = 55 °C, and 60 W non-repetitive peak reverse power dissipation (tp = 100 µs). It delivers stable voltage regulation in low-to-medium current bias circuits such as power supply reference rails and overvoltage protection clamps.
For engineers reviewing the BZV85-C68,113 datasheet, BZV85-C68,113 pinout, BZV85-C68,113 application, or BZV85-C68,113 equivalent, this device is selected for precision DC voltage stabilization where thermal stability, low leakage (<0.35 µA at 53 V), and robust surge handling (IZSM = 48 A, tp = 100 µs) are required in industrial control and instrumentation designs.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 68 V (min 64 V, max 72 V) at test current Itest = 48 mA. Its differential resistance is 200 Ω (max), and temperature coefficient is +60.5 mV/K at Itest, indicating positive drift with junction temperature - critical for temperature-compensated reference designs.
Thermal performance is defined by Rth(j-t) = 110 K/W (lead length 4 mm) and Rth(j-a) = 175 K/W (lead length 10 mm), requiring PCB copper area (1 cm² per lead) to sustain full 1.3 W dissipation. Non-repetitive surge capability is validated under half-sine (10 ms) and square-wave (100 µs) conditions per IEC 60134 limiting values.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4748A | 68 V nominal, ±5 %, Ptot = 1 W, rdif = 35 Ω max, Tj = 200 °C | Lower power rating limits continuous current to ~14.7 mA; unsuitable for >1 W sustained dissipation | Select when board space permits TO-204AA (DO-41) but thermal margin is constrained to 1 W |
| BZX85C68 | 68 V nominal, ±5 %, Ptot = 1.3 W, rdif = 150 Ω max, IR = 0.5 µA at 53 V | Higher leakage (0.5 µA vs. 0.35 µA) and lower surge rating (50 W vs. 60 W) | Prefer for cost-sensitive industrial designs where 0.15 µA leakage difference is acceptable |
Compared with 1N4748A and BZX85C68, BZV85-C68,113 offers superior surge resilience (60 W), tighter leakage control (0.35 µA), and identical 1.3 W thermal rating - making it optimal for high-reliability industrial clamping and reference applications demanding long-term parametric stability.

FAQ
What is the maximum continuous forward current for BZV85-C68,113?
The device is not intended for forward conduction; its absolute maximum forward current is 500 mA per IEC 60134 limiting values, but typical operation occurs in reverse breakdown. Forward voltage is 1 V at 50 mA - sufficient only for brief test or diagnostic conditions, not sustained use.
Can BZV85-C68,113 be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing spread in VZ and rdif, causing current imbalance. Parallel connection risks thermal runaway; derating or external ballast resistors are required, negating reliability benefits. Use a single higher-rated device instead.
How does the +60.5 mV/K temperature coefficient affect circuit design?
This positive coefficient means VZ increases ~4.1 V over a 68 °C rise (e.g., from 25 °C to 93 °C junction). For precision references, pair with a negative-coefficient device (e.g., forward-biased diode) or use temperature-compensated IC references where drift <10 ppm/°C is required.
Is the SOD66 package compatible with standard DO-41 footprint layouts?
Yes - SOD66 is the JEDEC-registered equivalent of DO-41, with identical mechanical dimensions (5.2 mm body length, 2.6 mm diameter, 0.81 mm lead diameter) and axial lead configuration. PCB footprints designed for DO-41 accept BZV85-C68,113 without modification.
