Product details
Overview
BZV85-C56,113 from Nexperia is a medium-power axial-leaded Zener 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 voltage reference or shunt regulator in low-to-medium current stabilization circuits, such as power supply feedback loops and overvoltage protection stages.
For engineers reviewing the BZV85-C56,113 datasheet, BZV85-C56,113 pinout, BZV85-C56,113 application, or BZV85-C56,113 equivalent, key selection criteria include its 56 V Zener voltage tolerance, differential resistance of 150 Ω at test current, temperature coefficient of +150 mV/K, and thermal resistance of 110 K/W (junction-to-tie-point), all critical for stable regulation under varying ambient and load conditions.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its terminals when biased above its nominal Zener voltage. Its design targets DC voltage stabilization rather than transient suppression, with specified performance at IZ = 5 mA and Tj = 25 °C.
The device exhibits a positive temperature coefficient (+150 mV/K) and a typical differential resistance of 150 Ω, indicating moderate regulation sensitivity to current variation. Thermal performance is defined with lead length constraints: Rth(j-t) = 110 K/W (4 mm lead length) and Rth(j-a) = 175 K/W (10 mm lead length on PCB).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 52 V to 60 V nominal range; ensures stable 56 V reference under ±5 % tolerance for feedback and sensing accuracy |
| Differential Resistance (rdif) | 150 Ω max at IZ = 5 mA; defines voltage deviation per mA change in Zener current |
| Temperature Coefficient (SZ) | +150 mV/K; quantifies Zener voltage drift with junction temperature rise |
| Total Power Dissipation (Ptot) | 1.3 W max at Ttp = 55 °C; sets maximum continuous DC power handling with thermal derating |
| Non-repetitive Peak Reverse Power (PZSM) | 60 W at tp = 100 µs; supports short-duration surge clamping without failure |
| Forward Voltage (VF) | ≤1 V at IF = 50 mA; confirms low conduction loss during forward bias testing or polarity verification |
| Reverse Current (IR) | ≤0.4 µA at VR = 42 V; specifies leakage level below breakdown threshold |
Pinout & Package
Hermetically sealed SOD66 (DO-41) axial glass package with 2 leads: cathode marked by a band, anode unmarked. Package dimensions: D = 2.6 mm max diameter, L = 25.4 mm max length, b = 0.81 mm max lead diameter.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal where Zener breakdown occurs |
| 2 (unmarked end) | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Ensures long-term parameter stability and moisture resistance in industrial environments |
| E24 ±5 % voltage tolerance | Enables precise binning for applications requiring tight reference voltage control |
| 1.3 W continuous power rating | Supports higher-current shunt regulation than standard 400 mW Zeners without heatsinking |
| 110 K/W junction-to-tie-point thermal resistance | Allows predictable thermal modeling when mounted with 4 mm lead length on PCB |
| 60 W non-repetitive surge capability | Provides margin against brief overvoltage transients in unregulated input stages |
Applications
| Power Supply Feedback Regulation | Overvoltage Clamp Protection |
|---|---|
Use Scenario: Used in the optocoupler feedback path of isolated AC/DC flyback converters to regulate output voltage. IC Role / Device Role / Timing Role: Zener diode provides precise 56 V reference to drive TL431 or similar shunt regulator IC. Use Value: Maintains ±1.5 % output regulation across line/load variations due to stable VZ and low rdif. |
Use Scenario: Placed across DC bus rails in motor drive inverters to limit transient overvoltage spikes. IC Role / Device Role / Timing Role: Acts as passive shunt clamp triggered only during >56 V excursions, diverting excess energy. Use Value: Absorbs up to 60 W for 100 µs without degradation, protecting downstream MOSFETs and gate drivers. |
| Reference Voltage Source | Signal Level Translation |
Use Scenario: Supplies stable bias voltage to analog comparators or ADC reference inputs in sensor signal conditioning circuits. IC Role / Device Role / Timing Role: Functions as a low-drift, low-noise DC reference node independent of supply ripple. Use Value: +150 mV/K temperature coefficient enables predictable compensation in temperature-critical measurement systems. |
Use Scenario: Shifts logic-level signals between 3.3 V and 5 V domains using resistor-Zener bias networks. IC Role / Device Role / Timing Role: Provides fixed 56 V clamping threshold to define upper rail for level-shifted analog control signals. Use Value: 150 Ω differential resistance ensures minimal loading error when sourcing ≤1 mA into high-impedance nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | 14 V Zener voltage, 1 W Ptot, DO-41 package, ±5 % tolerance | Lower voltage rating; unsuitable for 56 V systems but preferred for 12–15 V rail regulation | Select when target regulation voltage is 14 V and thermal budget is constrained to 1 W |
| BZX85C56 | Same 56 V rating and ±5 % tolerance, but 1.3 W Ptot and 175 K/W Rth(j-a) (vs. 110 K/W for BZV85-C56,113) | Higher thermal resistance reduces power handling in still-air conditions; identical electrical specs otherwise | Choose if legacy BZX85 footprint compatibility is required, accepting reduced thermal margin |
Compared with 1N4744A and BZX85C56, BZV85-C56,113 offers superior thermal performance (110 K/W vs. ≥175 K/W) for sustained 56 V regulation, while maintaining identical voltage tolerance and surge capability-making it optimal for space-constrained, thermally demanding industrial power designs.

FAQ
What is the maximum continuous reverse current this diode can handle at 56 V?
The BZV85-C56,113 is not rated for continuous reverse current at full Zener voltage; instead, its safe operating area is defined by power dissipation limits. At 56 V, the maximum continuous Zener current is approximately 23.2 mA (calculated from Ptot = 1.3 W ÷ 56 V), assuming no thermal derating and ideal heat sinking per datasheet condition [3]. Exceeding this risks thermal runaway.
Does this Zener diode have a specified noise performance for analog reference use?
No noise specification (e.g., RMS noise voltage or spectral density) is provided in the official Nexperia BZV85_SER datasheet. While the device is used in reference applications, its noise behavior is not characterized-designers requiring low-noise references should consider dedicated low-noise Zener ICs or verify empirically in circuit.
Can BZV85-C56,113 be used in parallel for higher power handling?
No-parallel connection of Zener diodes is not recommended due to mismatch in VZ and rdif, causing current hogging and thermal instability. The datasheet does not specify matching or parallel operation guidelines; for higher power, select a single higher-rated device or implement active regulation.
Is the SOD66 package RoHS-compliant and lead-free?
Yes-the BZV85-C56,113 is manufactured in compliance with RoHS Directive 2011/65/EU and is lead-free. Nexperia confirms halogen-free and green material content per their product compliance documentation, with no exemptions applied to this part number.
