Product details
Overview
BZX79-C62,133 from Nexperia is a ±5% tolerance Zener voltage regulator diode with nominal breakdown voltage of 62 V at 4 mA test current, 40 Ω typical differential resistance, and 0.4 mV/K temperature coefficient - designed for low-power voltage reference and stabilization in linear power supplies and sensor biasing circuits.
For engineers reviewing the BZX79-C62,133 datasheet, BZX79-C62,133 pinout, BZX79-C62,133 application, or BZX79-C62,133 equivalent, key selection criteria include Zener voltage tolerance (±5%), non-repetitive peak reverse power (40 W), thermal resistance (380 K/W), junction-to-ambient behavior under pulse conditions, and DO-35 package compatibility with through-hole PCB layouts.
Technical Context
This axial-leaded glass diode operates as a passive two-terminal shunt regulator, maintaining stable output voltage across load variations by conducting reverse current above its specified Zener voltage. Its 62 V nominal Zener voltage is characterized at IZtest = 4 mA, with 40 Ω typical dynamic impedance ensuring predictable regulation slope.
The device exhibits a positive temperature coefficient of +0.4 mV/K at 4 mA, indicating voltage increases with rising junction temperature - critical for thermal drift analysis in precision references. It is rated for 500 mW total power dissipation at Tamb = 50 °C with 8 mm lead length, and supports non-repetitive 100 μs surges up to 40 W.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 60.8 V to 66.0 V at IZ = 4 mA - defines stable regulation range for feedback or reference nodes |
| Differential Resistance (rdif) | 40 Ω typical at IZ = 4 mA - determines output voltage variation under load current changes |
| Temperature Coefficient (SZ) | +0.4 mV/K at IZ = 4 mA - quantifies voltage drift per degree Celsius rise in junction temperature |
| Reverse Current (IR) | 50 nA max at VR = 43.4 V (0.7 × VZnom) - ensures minimal leakage below regulation threshold |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 μs - enables transient overvoltage clamping without destruction |
| Total Power Dissipation (Ptot) | 500 mW at Tamb = 50 °C - sets continuous DC power limit under standard mounting conditions |
| Junction Temperature Range | −65 °C to +200 °C - defines operational and storage thermal envelope for industrial environments |
Pinout & Package
Hermetically sealed SOD27 (DO-35) axial glass package with cathode indicated by a colored band; leads are tinned copper alloy, suitable for wave or hand soldering. Dimensions: D = 1.85 mm max, L = 25.4 mm min, b = 0.56 mm max.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-side connection | Connected to circuit ground or lower potential node when used as shunt regulator |
| Cathode | Zener breakdown terminal / high-side connection | Connected to input or supply rail; reverse-biased to maintain regulated voltage at cathode-to-anode potential |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Enables cost-effective voltage referencing where tight regulation is not required, e.g., power supply feedback dividers |
| 40 W non-repetitive surge rating | Provides robust transient overvoltage protection in low-energy circuits without external TVS devices |
| DO-35 glass package with hermetic seal | Ensures long-term parameter stability and moisture resistance in harsh ambient conditions |
| Positive temperature coefficient (+0.4 mV/K) | Allows predictable thermal compensation when paired with negative-coefficient components in reference designs |
| 500 mW power rating at 50 °C ambient | Supports continuous operation in compact enclosures with limited airflow and no heatsinking |
Applications
| Power Supply Feedback Reference | Sensor Biasing Network |
|---|---|
Use Scenario: Used in the optocoupler feedback path of isolated AC/DC flyback converters to regulate output voltage. IC Role / Device Role / Timing Role: Shunt voltage reference providing stable 62 V reference point for TL431-like comparator circuits. Use Value: Maintains ±5% output regulation accuracy across line/load variations without active compensation. | Use Scenario: Supplies precise bias voltage to high-impedance piezoresistive pressure sensors in industrial transmitters. IC Role / Device Role / Timing Role: Passive voltage source establishing fixed common-mode level for ratiometric analog front-ends. Use Value: Delivers stable 62 V bias with <50 nA leakage, minimizing sensor offset drift and measurement error. |
| Overvoltage Clamp Protection | Calibration Voltage Standard |

IC Role / Device Role / Timing Role: Transient energy sink limiting voltage excursion to ≤66 V during turn-off events. Use Value: Absorbs 40 W for 100 μs without degradation, eliminating need for larger TVS diodes in space-constrained designs. | Use Scenario: Embedded in portable multimeter calibration circuits as traceable 62 V reference node. IC Role / Device Role / Timing Role: Stable, low-drift Zener element serving as secondary voltage standard against which DMM ADCs are trimmed. Use Value: Enables field-calibration with ±0.4 mV/K thermal predictability and <40 Ω dynamic impedance for low-load sensitivity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX79-B62,113 | ±2% tolerance (60.8–63.2 V), lower rdif (40 Ω max vs. 40 Ω typ), same DO-35 package | Higher precision required in feedback loops where 3% voltage window is insufficient | Select when tighter regulation stability outweighs cost sensitivity |
| 1N4742A | 62 V nominal, ±5%, but higher rdif (≤150 Ω), different DO-41 package, higher Ptot (1 W) | Used where higher continuous power handling or legacy DO-41 footprint is mandated | Select only if board layout requires DO-41 or >500 mW steady-state dissipation is needed |
Compared with BZX79-B62,113, the BZX79-C62,133 trades precision for cost and remains optimal for non-critical references; versus 1N4742A, it offers superior thermal resistance (380 vs. ~500 K/W) and tighter surge response due to smaller DO-35 junction mass.

FAQ
What is the maximum continuous reverse current this diode can handle at 62 V?
The BZX79-C62,133 does not specify a maximum continuous reverse current - instead, it is rated for 500 mW total power dissipation at 50 °C ambient. At 62 V, this corresponds to approximately 8.06 mA average Zener current (500 mW ÷ 62 V), assuming negligible forward drop and thermal derating.
Can this diode be used in surface-mount designs?
No - the BZX79-C62,133 uses an axial-leaded SOD27 (DO-35) glass package intended for through-hole mounting only. It lacks solder pads or terminations compatible with reflow or pick-and-place processes. For SMT alternatives, consider Nexperia's BZX384-C62 or PZMxx series.
How does the +0.4 mV/K temperature coefficient affect circuit performance?
A +0.4 mV/K coefficient means the Zener voltage increases by 0.4 mV per Kelvin rise in junction temperature. Over a 50 °C rise, voltage shifts +20 mV (≈0.032%), making it suitable for moderate-precision references where thermal gradients are controlled or compensated.
Is the cathode marking visible on the physical device?
Yes - the cathode is marked by a distinct color band (typically black or dark stripe) near one end of the DO-35 glass body. This band aligns with the cathode terminal in schematic symbols and must be oriented toward the higher-potential node in shunt regulator configurations.
