Product details
Overview
BZV85-C30,113 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 30 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 power linear power supplies and overvoltage protection circuits.
For engineers reviewing the BZV85-C30,113 datasheet, BZV85-C30,113 pinout, BZV85-C30,113 application, or BZV85-C30,113 equivalent, this part is selected for stable DC voltage stabilization where thermal management via PCB copper area and lead length is controllable, and where fast transient suppression with defined IZSM (21 A at tp = 100 µs) is required.
Technical Context
This Zener diode operates in reverse breakdown mode with a typical differential resistance of 45 Ω at 21 mA test current and exhibits a positive temperature coefficient of +22.4 mV/K near its 30 V nominal regulation point. Its junction-to-tie-point thermal resistance is 110 K/W with 4 mm lead length, enabling predictable thermal derating in PCB-mounted designs.
The device complies with IEC 60134 absolute maximum ratings, supports 500 mA forward current, and maintains regulation stability across −65 °C to +200 °C storage and operating junction temperatures. Its 1.0 pF capacitance at 1 MHz and 0.05 µA reverse leakage at 21 V make it suitable for low-noise analog references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 30 V (28.0 V min / 32.0 V max); defines precise shunt regulation point under 21 mA test current |
| Power Dissipation | 1.3 W (at Ttp = 55 °C, 4 mm from body); sets maximum continuous DC power handling with thermal tie-point cooling |
| Peak Reverse Power | 60 W (100 µs square wave); enables short-duration surge clamping without failure |
| Differential Resistance | 45 Ω (at IZ = 21 mA); determines output impedance and load regulation error sensitivity |
| Temperature Coefficient | +22.4 mV/K (at IZ = 21 mA); quantifies voltage drift per degree Celsius rise in junction temperature |
| Reverse Leakage Current | 0.05 µA (at VR = 21 V); ensures minimal quiescent current draw in standby regulation circuits |
| Forward Voltage | 1.0 V (at IF = 50 mA); defines conduction threshold when used in series polarity configurations |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with cathode indicated by a colored band; leads are tinned copper alloy, compatible with wave and reflow soldering (per Nexperia recommendations).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during Zener operation; carries full load current in shunt configuration |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential rail; completes current path during regulation; must be thermally anchored for power dissipation |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5257BRLG | 30 V nominal, ±5 %, 0.5 W rating, DO-35 package, higher Rdif (35 Ω), lower IZSM (10 A) | Limited to low-power biasing; unsuitable for >0.5 W continuous dissipation or high-energy transients | Select only when board space is constrained and thermal budget is ≤0.5 W |
| BZX85C30 | 30 V nominal, ±5 %, 1.3 W rating, DO-41 package, identical power and surge specs, but plastic encapsulation | Lower moisture resistance and long-term parameter drift vs. hermetic glass; reduced reliability in humid/high-T environments | Prefer BZV85-C30,113 where field lifetime >15 years or humidity exposure >85 % RH is expected |
Compared with 1N5257BRLG and BZX85C30, BZV85-C30,113 delivers superior thermal stability and surge endurance due to its hermetic SOD66 construction and validated 60 W pulse capability - critical for industrial and automotive applications demanding proven long-term reliability.

FAQ
What is the maximum continuous power dissipation for BZV85-C30,113 under standard PCB mounting?
The maximum continuous power dissipation is 1.3 W when leads are maintained at 55 °C at 4 mm from the diode body, per Nexperia's limiting values table. This assumes 1 cm² copper area per lead on FR-4 PCB. At ambient 25 °C with 10 mm lead length, the rating drops to 1.0 W due to higher thermal resistance.
How does the temperature coefficient affect regulation accuracy across operating temperature?
With a specified +22.4 mV/K coefficient at 21 mA, the Zener voltage increases by approximately 0.075 %/°C near 30 V. Over a −40 °C to +125 °C junction range, this yields ±2.2 V drift - compensated in precision designs via TC-matched resistor networks or active correction.
Can BZV85-C30,113 be used in series or parallel configurations?
Series connection is valid for higher voltage references but requires matched units to avoid current imbalance; parallel use is not recommended due to negative dynamic resistance interaction and thermal runaway risk. Nexperia specifies single-device operation only.
What is the significance of the "C" in BZV85-C30,113?
The "C" denotes the E24 tolerance series (±5 %), distinguishing it from "A" (±1 %) and "B" (±2 %) variants. The "30" indicates nominal Zener voltage of 30 V, and "113" is Nexperia's internal package and reel code for SOD66 in 1000-piece tape-and-reel format.
