Product details
Overview
BZV85-C36,133 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 36 V nominal working voltage with ±5 % tolerance, 1.3 W total power dissipation, and 60 W non-repetitive peak reverse power. 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-C36,133 datasheet, BZV85-C36,133 pinout, BZV85-C36,133 application, or BZV85-C36,133 equivalent, this device is selected for stable DC voltage stabilization where thermal resistance to tie-point (110 K/W) and low differential resistance (50 Ω max at test current) are critical for regulation accuracy under varying load conditions.
Technical Context
The BZV85-C36,133 operates as a two-terminal shunt regulator, maintaining a stable 34.0–38.0 V reverse breakdown voltage (VZ) at 25 mA test current. Its temperature coefficient of +27.2 mV/K ensures predictable positive drift with junction temperature rise, enabling compensation in temperature-sensitive references.
It exhibits a maximum differential resistance of 50 Ω at IZ = 25 mA, supporting tight regulation under dynamic load changes. With non-repetitive peak reverse current capability up to 25 A (tp = 100 µs), it withstands transient surges without degradation when mounted per specified PCB copper area (1 cm²/lead).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 36 V (34.0–38.0 V range at 25 mA; enables precise mid-range DC rail stabilization) |
| Tolerance | ±5 % (E24 series compliance; supports standard BOM planning without custom calibration) |
| Total Power Dissipation | 1.3 W (at Ttp = 55 °C, 4 mm from body; defines continuous thermal envelope on PCB) |
| Differential Resistance | ≤50 Ω (at IZ = 25 mA; ensures <0.5 V output shift per 25 mA load change) |
| Non-repetitive Peak Reverse Power | 60 W (tp = 100 µs square wave; protects against ESD and line transients) |
| Forward Voltage | ≤1 V (at IF = 50 mA; confirms low-loss conduction in forward-biased clamp configurations) |
| Junction Temperature Limit | 200 °C (supports operation in high-ambient industrial environments with derating) |
Pinout & Package
Hermetically sealed axial-leaded SOD66 (DO-41) glass package with cathode indicated by a colored band. Leads are tinned copper-clad steel; body diameter 2.6 mm, length 5.2 mm, lead spacing 25.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (banded end) | Cathode | Connected to regulated output node; reverse-biased during regulation; carries full Zener current |
| 2 (non-banded end) | Anode | Connected to ground or lower-potential reference; completes shunt path for excess current |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass sealing | Prevents moisture ingress and long-term parameter drift in humid or outdoor environments |
| 110 K/W junction-to-tie-point thermal resistance | Enables predictable thermal modeling for PCB copper area design (1 cm²/lead required) |
| Positive temperature coefficient (+27.2 mV/K) | Allows series stacking with negative-coefficient devices for near-zero TC references |
| Low reverse leakage (≤0.05 µA at VR = 25.2 V) | Minimizes quiescent current in battery-powered voltage monitor circuits |
| Standard E24 voltage grading | Ensures interchangeability across 33 variants without redesigning bias networks |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4738A | Same 36 V nominal rating but ±5 % tolerance, 1 W Ptot, TO-204AA (DO-41) package | Limited to 1 W continuous dissipation; requires larger copper area for equivalent thermal performance | Select when legacy footprint compatibility is mandatory and peak power demands stay below 1 W |
| BZX85C36 | 36 V Zener, ±5 %, 1.3 W, but higher differential resistance (70 Ω) and no published Rth(j-t) | Less precise regulation under fast load transients; thermal behavior less predictable on constrained PCBs | Select only for cost-sensitive, non-critical stabilization where 0.5 V regulation window is acceptable |
Compared with 1N4738A and BZX85C36, the BZV85-C36,133 delivers superior thermal predictability (110 K/W Rth(j-t)) and tighter dynamic regulation (50 Ω rdif), making it preferred for industrial designs requiring long-term stability and transient resilience without thermal derating penalties.

FAQ
What is the maximum continuous reverse current the BZV85-C36,133 can sustain at 25 °C ambient?
The device sustains up to 25 mA continuous reverse current at 25 °C ambient when mounted with 1 cm² copper per lead, corresponding to its 36 V nominal Zener voltage and 1.3 W power rating. Exceeding this current without thermal derating risks junction temperature exceeding 200 °C, triggering permanent parametric shift or failure.
How does the +27.2 mV/K temperature coefficient affect circuit design?
This positive temperature coefficient means the Zener voltage increases by 27.2 mV per Kelvin rise in junction temperature. Designers use it to counteract negative TC elements-such as silicon-based sensors or other Zeners-in compensated reference strings, achieving net TC values below 50 ppm/°C in precision instrumentation.
Can the BZV85-C36,133 be used in parallel for higher current handling?
No-Zener diodes exhibit manufacturing spread in VZ and dynamic impedance, causing current hogging when paralleled. Even matched units require individual ballast resistors, which defeat the purpose of parallelization. For >25 mA regulation, use a series-pass transistor driven by the BZV85-C36,133 reference instead.
Is the SOD66 (DO-41) package compatible with automated through-hole assembly?
Yes-the SOD66 package has standardized axial leads with 25.4 mm pitch and tinned finishes, fully compatible with wave soldering and selective soldering equipment. Lead coplanarity and diameter (0.81 mm max) meet IPC-A-610 Class 2 requirements for industrial-grade through-hole assembly.
