Product details
Overview
BZV85-C56,133 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 56 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 handling. It serves as a precision DC voltage reference or shunt regulator in low-to-medium current stabilization circuits.
For engineers reviewing the BZV85-C56,133 datasheet, BZV85-C56,133 pinout, BZV85-C56,133 application, or BZV85-C56,133 equivalent, key selection criteria include Zener voltage accuracy (52–60 V), differential resistance (150 Ω max), temperature coefficient (+150 mV/K), junction-to-tie-point thermal resistance (110 K/W), and compliance with IEC 60134 absolute maximum ratings.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable output voltage across varying load currents. Its 56 V nominal Zener voltage is specified at 39 mA test current, with typical differential resistance of 150 Ω and positive temperature coefficient of +150 mV/K - indicating voltage increases with junction temperature.
Thermal performance is defined under two mounting conditions: 1.3 W power dissipation with leads held at 55 °C at 4 mm from body, and 1 W with ambient at 25 °C and 10 mm lead length. Non-repetitive surge capability supports 60 W for 100 µs square-wave pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 52 V to 60 V at IZ = 39 mA - defines regulated output range under nominal bias |
| Differential Resistance (rdif) | ≤150 Ω - determines regulation stiffness against load current variation |
| Temperature Coefficient (SZ) | +150 mV/K - quantifies voltage drift per degree rise in junction temperature |
| Total Power Dissipation (Ptot) | 1.3 W with Ttp = 55 °C at 4 mm lead distance - sets continuous thermal limit on PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 60 W for tp = 100 µs - enables transient overvoltage clamping without failure |
| Reverse Current (IR) | ≤0.05 µA at VR = 43 V - ensures minimal leakage in standby regulation |
| Forward Voltage (VF) | ≤1 V at IF = 50 mA - defines conduction threshold in forward-biased protection paths |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with 2 terminals; cathode identified by a colored band on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential reference; completes bias path |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Ensures long-term stability and moisture resistance in harsh environments |
| E24 ±5 % voltage tolerance | Enables cost-effective selection within standardized voltage ladder (3.6–75 V) |
| 110 K/W junction-to-tie-point thermal resistance | Supports reliable heat transfer when mounted with 4 mm lead length on PCB |
| 60 W surge rating (100 µs) | Provides robust transient overvoltage suppression without derating |
| Low leakage (≤0.05 µA @ 43 V) | Minimizes quiescent current draw in battery-powered or high-impedance reference designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5256B | Same 56 V nominal Zener voltage, but ±5 % tolerance, 0.5 W power rating, DO-35 package | Limited to lower-power applications due to 0.5 W Ptot; unsuitable for >20 mA continuous loads | Select when board space is constrained and thermal budget is low; verify thermal derating at elevated ambient |
| BZX85C56 | 56 V Zener, ±5 %, 1.3 W rating, but plastic DO-41 package (not hermetic glass) | Lower moisture resistance and long-term parameter stability vs. glass-sealed BZV85 series | Prefer for cost-sensitive industrial controls where hermeticity is not required for lifetime reliability |
Compared with 1N5256B and BZX85C56, BZV85-C56,133 delivers superior thermal performance (1.3 W at 55 °C tie-point), hermetic reliability, and tighter long-term voltage stability - making it optimal for mission-critical analog references and surge-prone power rails.

FAQ
What is the maximum continuous Zener current for BZV85-C56,133 at 25 °C ambient?
At Tamb = 25 °C with 10 mm lead length, the maximum continuous Zener current is calculated as Ptot/VZ ≈ 1 W / 56 V ≈ 17.9 mA. Derating applies above 25 °C per Rth(j-a) = 175 K/W; full 1.3 W rating requires maintaining tie-point temperature at 55 °C.
How does the +150 mV/K temperature coefficient affect circuit performance?
A +150 mV/K coefficient means the Zener voltage increases by approximately 8.4 mV per °C rise in junction temperature. For a 50 °C ΔT, this yields +420 mV shift - critical in precision references; compensation or temperature-controlled layouts may be needed for <0.1 % stability.
Can BZV85-C56,133 be used in parallel for higher power handling?
No - Zener diodes exhibit negative dynamic resistance and mismatched VZ tolerances, causing current hogging. Parallel operation risks thermal runaway. For higher power, use a single higher-rated device or active regulation with a pass transistor.
Is the SOD66 package compatible with standard DO-41 footprint on PCBs?
Yes - SOD66 is the JEDEC-registered designation for DO-41. The package has identical 2.6 mm diameter, 25.4 mm overall length, and 0.81 mm lead diameter, ensuring mechanical and soldering compatibility with legacy DO-41 footprints and assembly processes.
