Product details
Overview
BZV85-C9V1,133 from Nexperia is a medium-power Zener voltage regulator diode in a hermetically sealed SOD66 (DO-41) glass package, rated for 9.1 V nominal stabilization at 6.5 mA test current, with ±5 % tolerance, 25 Ω typical differential resistance, and +3.8 mV/K temperature coefficient. It delivers stable reference voltage in low-to-medium power linear regulators and overvoltage protection circuits.
For engineers reviewing the BZV85-C9V1,133 datasheet, BZV85-C9V1,133 pinout, BZV85-C9V1,133 application, or BZV85-C9V1,133 equivalent, key selection criteria include its 9.1 V Zener voltage, 1.3 W steady-state power dissipation on PCB with 1 cm² copper per lead, 60 W non-repetitive peak reverse power handling, and axial-leaded SOD66 mechanical compatibility with legacy through-hole designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain a precise DC reference voltage under varying load and input conditions. Its +3.8 mV/K positive temperature coefficient ensures predictable drift across −65 °C to +200 °C junction temperature range, and its 25 Ω differential resistance minimizes output impedance variation with current.
The device is optimized for stabilization in analog power supplies and signal conditioning circuits where thermal stability and repeatable clamping behavior are required. It supports both continuous DC regulation and transient surge suppression via its 60 W non-repetitive peak reverse power rating at 100 µs pulse width.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4739A | 9.1 V, ±5 %, 1 W Ptot, 20 Ω rdif, DO-41 package | Limited to 1 W continuous dissipation; unsuitable for sustained >1 W loads | Select when board layout restricts thermal copper area and average power remains <0.8 W |
| BZX85C9V1 | 9.1 V, ±5 %, 1.3 W Ptot, 25 Ω rdif, DO-41 package, same thermal specs | Identical electrical and thermal performance; differs only in manufacturer branding and traceability | Choose for dual-sourcing flexibility while maintaining identical board-level behavior and qualification data |

FAQ
What is the maximum continuous forward current for BZV85-C9V1,133?
The device is not rated for continuous forward conduction; its absolute maximum forward current is 500 mA per IEC 60134 limiting values, but typical operation occurs in reverse breakdown. Forward voltage is specified at 50 mA (≤1 V), and sustained forward bias risks thermal runaway or parameter shift.
Can BZV85-C9V1,133 be used in surface-mount designs?
No - it uses an axial-leaded SOD66 (DO-41) glass package intended for through-hole mounting. Its 25.4 mm length and 2.6 mm diameter require drilled PCB holes and wave soldering or hand assembly; no SMD variant exists in this series.
How does the +3.8 mV/K temperature coefficient affect circuit performance?
This positive coefficient causes the Zener voltage to increase by 3.8 mV per Kelvin rise in junction temperature. In precision references, it must be compensated using negative-tempco components or calibrated in system-level firmware; unmitigated, it contributes ~0.4 % drift over a 100 °C junction swing.
What is the recommended PCB layout for optimal thermal performance?
Mount with 10 mm lead length and provide ≥1 cm² copper area per lead on the PCB to achieve the rated 1.3 W dissipation. Avoid narrow traces or isolated pads; connect leads directly to internal or external copper planes using thermal vias if layer stacking permits.
