Product details
Overview
BZV85-C15,133 from Nexperia is a medium-power axial-leaded Zener diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 15 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 delivers stable voltage regulation in low-to-medium current bias circuits such as power supply reference rails and overvoltage protection clamps.
For engineers reviewing the BZV85-C15,133 datasheet, BZV85-C15,133 pinout, BZV85-C15,133 application, or BZV85-C15,133 equivalent, key selection criteria include its 15 V Zener voltage tolerance, 15 Ω typical differential resistance at test current, −1.0 to +8.9 mV/K temperature coefficient, and suitability for PCB-mounted stabilization where thermal management via copper area is feasible.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified nominal Zener voltage of 13.8 V to 15.6 V at 5 mA test current, exhibiting a temperature coefficient ranging from −1.0 to +8.9 mV/K depending on operating current. Its differential resistance is 15 Ω max at 5 mA, ensuring predictable regulation under varying load conditions.
The device features a junction-to-tie-point thermal resistance of 110 K/W (lead length 4 mm) and junction-to-ambient resistance of 175 K/W (lead length 10 mm), supporting reliable operation up to 200 °C junction temperature when mounted on PCBs with ≥1 cm² copper per lead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 13.8 V to 15.6 V at 5 mA test current - defines stable regulation point for reference or clamp applications |
| Tolerance | ±5 % - ensures predictable voltage accuracy across production lots without binning |
| Differential Resistance (rdif) | 15 Ω max at 5 mA - determines output impedance and regulation sensitivity to current changes |
| Power Dissipation (Ptot) | 1.3 W max at 25 °C ambient with 10 mm leads - sets continuous DC power handling limit on standard PCB layout |
| Peak Reverse Power (PZSM) | 60 W for 100 µs square wave - enables transient surge suppression in pulse-limited protection circuits |
| Reverse Current (IR) | 760 µA max at 10.5 V - quantifies leakage below knee voltage, critical for low-power bias networks |
| Forward Voltage (VF) | 1.0 V max at 50 mA - defines conduction loss when used in forward-biased configurations (e.g., polarity protection) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | 15 V nominal, ±5 % tolerance, 1 W Ptot, DO-41 package, 16 Ω rdif | Lower continuous power rating limits use in >15 mA bias networks without derating | Select when legacy design compatibility or distributor stock availability outweighs 0.3 W power margin |
| BZX85C15 | 15 V nominal, ±5 %, 1.3 W Ptot, DO-41, but higher 20 Ω rdif and 1000 µA IR at 10.5 V | Reduced regulation precision and higher leakage affect low-power reference stability | Prefer for cost-sensitive consumer applications where 15 V accuracy and leakage are less critical |
Compared with 1N4744A and BZX85C15, BZV85-C15,133 offers identical voltage rating and tolerance but superior thermal performance (110 K/W Rth(j-t)) and tighter leakage (760 µA), making it optimal for industrial-grade reference and clamp designs requiring long-term stability.

FAQ
What is the maximum continuous reverse current this Zener can handle at 25 °C?
The BZV85-C15,133 supports a maximum forward current of 500 mA, but its continuous reverse (Zener) current is limited by power dissipation. At 25 °C ambient and 10 mm lead length, the 1.3 W rating allows up to 86.7 mA at 15 V (P = V × I), assuming no additional thermal resistance from PCB layout.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a specified temperature coefficient of −1.0 to +8.9 mV/K, the Zener voltage shift across this range is approximately −0.22 V to +1.11 V relative to 25 °C. This results in a worst-case VZ spread of 13.58 V to 16.71 V, requiring system-level compensation if sub-1 % accuracy is required.
Can this diode be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing variations in VZ and dynamic resistance, causing current imbalance when paralleled. Even matched units risk thermal runaway due to positive tempco above ~5 V; external ballast resistors or dedicated regulators are required for higher power.
Is the SOD66 package compatible with standard DO-41 footprint and reflow profiles?
Yes - SOD66 is the JEDEC-registered designation for DO-41. The 2.6 mm diameter glass body and 25.4 mm lead spacing match standard DO-41 footprints. Hand-soldering and wave soldering are supported; reflow is not recommended due to glass thermal shock risk.
