Product details
Overview
BZV85-C16,133 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 16 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 shunt reference in low-to-medium current stabilization circuits, commonly used in power supply feedback loops, overvoltage clamping, and analog voltage reference generation.
For engineers reviewing the BZV85-C16,133 datasheet, BZV85-C16,133 pinout, BZV85-C16,133 application, or BZV85-C16,133 equivalent, key selection criteria include its 15.3–17.1 V Zener voltage range, 10.7–15.4 Ω differential resistance at test current, +10.7 mV/K temperature coefficient, 1.75 mA maximum reverse current at 11 V, and suitability for PCB-mounted thermal management with 1 cm² copper per lead.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage across its terminals under varying load and line conditions. Its E24-standardized 16 V nominal rating targets mid-range regulation needs where tighter tolerance and predictable thermal drift are required over generic alternatives.
Designed for mounting on PCBs with defined copper area per lead, it leverages 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), enabling reliable operation up to 200 °C junction temperature during transient surges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.3 V min to 17.1 V max at Itest = 5 mA - defines regulated output range under standard test conditions |
| Differential Resistance (rdif) | 10.7 Ω typ to 15.4 Ω max at Itest = 5 mA - determines output impedance and regulation sensitivity to current changes |
| Temperature Coefficient (SZ) | +10.7 mV/K typ - quantifies voltage drift per degree Celsius rise, critical for temperature-stable references |
| Reverse Current (IR) | ≤1.75 µA max at VR = 11 V - ensures low leakage in high-impedance bias networks |
| Non-repetitive Peak Power (PZSM) | 60 W max for 100 µs square wave - supports transient overvoltage suppression without failure |
| Total Power Dissipation (Ptot) | 1.3 W max at Ttp = 55 °C - sets continuous thermal limit for PCB-mounted operation |
| Forward Voltage (VF) | ≤1.0 V at IF = 50 mA - relevant for polarity-checking or dual-use rectifier applications |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with cathode indicated by a colored band; leads are tinned copper-clad steel, suitable for through-hole PCB assembly and wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased terminal during Zener operation |
| 2 (unbanded end) | Anode | Connected to circuit ground or lower-potential rail; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Ensures long-term stability and moisture resistance in industrial environments |
| E24-standardized voltage grading | Enables precise binning across 33 types (3.6 V–75 V), supporting design reuse and inventory consolidation |
| ±5 % nominal voltage tolerance | Meets cost-sensitive industrial regulation requirements without requiring post-calibration |
| 1.3 W continuous power rating | Supports higher-current shunt regulation than standard 400 mW Zeners, reducing need for external series resistors |
| 110 K/W junction-to-tie-point thermal resistance | Enables predictable thermal derating when mounted with 4 mm lead length and controlled PCB copper area |
Applications
| Power Supply Feedback Loop | Overvoltage Clamp Circuit |
|---|---|

Use Value: Enables <1 % current accuracy with 5 mA test current and 15 Ω rdif, reducing calibration overhead. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4742A | 12 V nominal, 1 W Ptot, DO-41 package, ±5 % tolerance | Lacks 16 V rating; requires redesign if exact voltage level is mandatory | Select only if system allows 12 V reference and lower power budget suffices |
| BZX85C16 | Same 16 V rating, but 1.3 W Ptot at 25 °C ambient (not tie-point), higher rdif (20 Ω typ) | Less stable under thermal variation due to higher thermal resistance and weaker tempco control | Prefer BZV85-C16,133 where PCB copper layout enables tie-point cooling and tighter regulation is needed |
Compared with 1N4742A and BZX85C16, BZV85-C16,133 offers superior thermal performance via tie-point-rated power dissipation, lower differential resistance, and a well-characterized positive temperature coefficient-making it optimal for precision-stable, thermally managed shunt references.

FAQ
What is the maximum continuous reverse current this diode can handle at 16 V?
The BZV85-C16,133 is not rated for continuous reverse conduction at 16 V; it operates in Zener breakdown mode with a specified test current of 5 mA. At 11 V reverse bias, its maximum reverse current is 1.75 µA. Continuous operation must remain within its 1.3 W power limit, translating to ≤81 mA at 16 V - but practical design uses series resistance to limit current to 5–20 mA for stability and longevity.
How does the +10.7 mV/K temperature coefficient affect circuit accuracy over −40 °C to +125 °C?
With a +10.7 mV/K coefficient, the Zener voltage shifts approximately +1.77 V across a 165 °C range (−40 °C to +125 °C), resulting in ±5.5 % deviation from nominal 16 V. This is acceptable for non-precision applications but requires compensation (e.g., complementary tempco components) in high-accuracy references.
Can this diode be used in surface-mount designs?
No - the BZV85-C16,133 uses an axial-leaded SOD66 (DO-41) glass package designed exclusively for through-hole mounting. It lacks SMD-compatible terminations or reflow-suitable construction. For SMT equivalents, consider Nexperia's BZX384-B16 or BZT52-B16 series in SOD-323 packages.
What is the significance of "tie-point" in the 1.3 W power rating?
The 1.3 W rating assumes leads are held at 55 °C at 4 mm from the diode body (the "tie-point"), reflecting real-world PCB thermal management with defined copper area. This differs from ambient-rated specs and provides a more accurate derating basis when board layout controls heat flow - unlike the 1 W rating specified at 25 °C ambient with 10 mm leads.
