Product details
Overview
BZV85-C24,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 24 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at 25 °C, and 60 W non-repetitive peak reverse power. It delivers stable voltage reference in low-to-medium current regulation circuits, such as power supply feedback loops and overvoltage protection stages.
For engineers reviewing the BZV85-C24,113 datasheet, BZV85-C24,113 pinout, BZV85-C24,113 application, or BZV85-C24,113 equivalent, this page provides verified electrical parameters, thermal resistance data (Rth(j-a) = 175 K/W), differential resistance (rdif ≤ 30 Ω), temperature coefficient (SZ = +18.3 to +24.3 mV/K), and PCB-mounting guidance per IEC 60134 limiting values.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified test current of 17 mA, delivering precise DC voltage stabilization across ambient temperatures from −65 °C to +200 °C junction limit. Its axial-leaded SOD66 package enables through-hole mounting on PCBs with ≥1 cm² copper area per lead for thermal management.
The device exhibits a positive temperature coefficient (+18.3 to +24.3 mV/K) above 7.5 V nominal voltage, ensuring predictable drift under thermal load. Non-repetitive surge capability supports transient suppression up to 100 µs square-wave pulses at 60 W, validated under Tj = 25 °C pre-surge conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 22.8 V to 25.6 V at Itest = 17 mA - defines stable regulation range for feedback or clamp circuits |
| Differential Resistance (rdif) | ≤ 30 Ω - determines output impedance and load regulation sensitivity |
| Temperature Coefficient (SZ) | +18.3 to +24.3 mV/K - quantifies voltage drift per degree Celsius rise in junction temperature |
| Total Power Dissipation (Ptot) | 1.3 W at Tamb = 25 °C, 10 mm lead length - sets maximum continuous DC power handling on standard PCB |
| Non-repetitive Peak Reverse Power (PZSM) | 60 W at tp = 100 µs - supports short-duration surge suppression without failure |
| Forward Voltage (VF) | ≤ 1 V at IF = 50 mA - confirms low-loss conduction in forward-biased protection paths |
| Junction Temperature (Tj) | −65 °C to +200 °C - specifies operational and storage thermal envelope for industrial environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4749A | 24 V nominal, ±5 %, Ptot = 1 W, DO-41 package, Rth(j-a) = 190 K/W | Lower continuous power rating limits use in >1 W regulation; identical pinout and marking polarity | Select when legacy footprint compatibility is required and thermal margin allows 1 W derating |
| BZX85C24 | 24 V nominal, ±5 %, Ptot = 1.3 W, DO-41, but higher rdif (≤40 Ω) and wider SZ range (+19 to +27 mV/K) | Slightly reduced regulation precision under varying load/temperature; same surge rating | Choose for cost-sensitive industrial designs where ±2 % regulation tolerance is acceptable |
Compared with 1N4749A and BZX85C24, BZV85-C24,113 offers superior thermal resistance (175 vs. 190 K/W), tighter differential resistance (≤30 Ω), and narrower temperature coefficient spread, making it optimal for high-stability 24 V reference and clamp functions in space-constrained PCBs.

FAQ
What is the maximum continuous reverse current for BZV85-C24,113 at 24 V regulation?
The device is characterized at a test current (Itest) of 17 mA for nominal 24 V operation. Continuous reverse current must remain within the 1.3 W power limit: at 24 V, this corresponds to ≤54 mA (P = V × I → I = 1.3 W / 24 V). Exceeding this risks thermal runaway due to junction temperature exceeding 200 °C.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified SZ of +18.3 to +24.3 mV/K, the Zener voltage increases by approximately 0.5–0.7 V across a 25 °C to 75 °C ambient range. This drift is linear and predictable, enabling compensation in feedback networks or acceptable for applications tolerating ±1 % output variation.
Can BZV85-C24,113 be used in surface-mount designs?
No - it uses an axial-leaded SOD66 (DO-41) glass package designed exclusively for through-hole mounting. Surface-mount equivalents like BZX384-C24 (SOD-323) exist but differ in thermal performance, surge rating, and package dimensions; direct substitution requires layout and thermal redesign.
What PCB layout practices optimize thermal performance?
Mount with ≥1 cm² copper area per lead, using thermal relief pads and minimum 0.5 mm trace width. Keep leads at least 4 mm from body to maintain Ttp = 55 °C at tie-point; avoid enclosing the glass body in conformal coating or potting compounds that impede heat dissipation.
