Product details
Overview
BZV85-C27,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 27 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation at 25 °C ambient, and 60 W non-repetitive peak reverse power handling. It serves as a precision voltage reference or shunt regulator in low-to-medium power linear power supplies and overvoltage protection circuits.
For engineers reviewing the BZV85-C27,113 datasheet, BZV85-C27,113 pinout, BZV85-C27,113 application, or BZV85-C27,113 equivalent, this page delivers verified electrical parameters, thermal behavior under PCB mounting conditions, cathode/anode terminal mapping, and validated alternatives for voltage stabilization design.
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 27 V nominal Zener voltage (25.1–28.9 V range), 40 Ω typical differential resistance at test current, and +20.1 mV/K temperature coefficient define its regulation accuracy and thermal drift behavior.
Designed for PCB mounting with 1 cm² copper area per lead, it achieves 110 K/W junction-to-tie-point thermal resistance (4 mm lead length) and supports surge handling up to 19 A peak reverse current (tp = 100 µs, square wave) while maintaining junction temperature ≤200 °C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4733A | 27 V nominal, ±5 % tolerance, 1 W power rating, DO-41 package, 35 Ω rdif | Limited to lower steady-state power (1 W vs. 1.3 W); less robust under sustained load | Select when board space matches DO-41 but thermal margin is sufficient and cost is prioritized |
| BZX85C27 | 27 V nominal, ±5 % tolerance, 1.3 W rating, DO-41 package, 45 Ω rdif, −65 °C to +200 °C Tstg | Higher differential resistance reduces regulation precision; identical thermal envelope | Choose when legacy BZX85 footprint compatibility is required and 5 Ω rdif penalty is acceptable |
Compared with 1N4733A and BZX85C27, BZV85-C27,113 offers superior thermal performance (1.3 W rating with verified PCB derating), tighter regulation fidelity (40 Ω rdif), and consistent Nexperia manufacturing traceability-making it optimal for industrial power monitoring and high-reliability clamp circuits.

FAQ
What is the maximum continuous reverse current this diode can handle at 27 V?
At 27 V nominal Zener voltage, BZV85-C27,113 is rated for a test current (Itest) of 19 mA, with a maximum continuous reverse current limited by power dissipation: at 25 °C ambient and 10 mm leads, 1.3 W allows ~48 mA (1.3 W ÷ 27 V). Derating applies above 25 °C per Rth(j-a) = 175 K/W.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a +20.1 mV/K temperature coefficient, BZV85-C27,113 exhibits ~1.7 V increase in VZ over a 85 K rise (−40 °C to +125 °C), shifting nominal 27 V to ~28.7 V. This drift is predictable and compensated in precision references using complementary components or calibration.
Can this diode be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, slight VZ mismatches cause current hogging. Parallel use risks thermal runaway; external ballast resistors or dedicated regulators are required for >1.3 W needs.
Is the SOD66 package compatible with standard DO-41 footprints on PCBs?
Yes-SOD66 is the JEDEC-registered designation for DO-41. The package has identical 2.6 mm body diameter, 4.8 mm minimum length, and 0.81 mm lead diameter, ensuring mechanical and soldering compatibility with legacy DO-41 land patterns and automated assembly equipment.
