Product details
Overview
1N6013B_T50R from Fairchild Semiconductor is a 34.2 V ±5% Zener diode in DO-35 glass package, rated for 500 mW power dissipation at TL ≤ 75°C with 4.0 mW/°C derating, 95 Ω zener impedance at 5 mA test current, and 0.1 mA leakage current at 27 V reverse voltage. It serves as a precision voltage reference or overvoltage clamp in low-power analog regulation circuits.
For engineers reviewing the 1N6013B_T50R datasheet, pinout, applications, or equivalent options, key selection criteria include its 34.2 V nominal zener voltage, DO-35 axial leaded package, 5 mA test current, 95 Ω dynamic impedance, and -65°C to +200°C operating temperature range.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable voltage across its terminals under varying load and line conditions. Its 5% tolerance and 95 Ω zener impedance at 5 mA ensure predictable regulation performance in feedback networks and reference stages.
The device uses a glass-passivated junction in a DO-35 hermetically sealed package, enabling reliable operation up to +200°C junction temperature. Thermal derating begins at 75°C lead temperature, with linear 4.0 mW/°C reduction in power handling capability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6013B (ON Semiconductor) | Identical 34.2 V rating, same DO-35 package, but 100 Ω ZZ vs. 95 Ω and 0.5 mA IR at 27 V vs. 0.1 mA | Higher leakage reduces suitability in battery-critical IoT nodes; acceptable in mains-powered industrial regulators | Select 1N6013B_T50R when lowest possible leakage and tighter impedance are required for precision references |
| BZX55-C33 (Vishay) | 33 V nominal (31.35–34.65 V), DO-35, 500 mW, but 130 Ω ZZ at 5 mA and 100 nA IR at 25 V | Lower voltage and higher impedance limit use in 34.2 V-specific feedback loops; superior leakage suits ultra-low-power designs | Choose BZX55-C33 only if 33 V is acceptable and sub-µA leakage outweighs regulation stiffness requirements |
Compared with 1N6013B_T50R, the ON Semiconductor 1N6013B offers identical voltage but higher leakage and impedance, while Vishay's BZX55-C33 trades 1.2 V lower nominal voltage for dramatically lower leakage-making 1N6013B_T50R optimal where 34.2 V regulation and 95 Ω impedance are design-critical.

This value is measured under thermal equilibrium at 30°C ±1°C lead temperature with 3/8" lead length, as specified in the Fairchild datasheet Rev. C2.
What package type does the 1N6013B_T50R use?
The 1N6013B_T50R uses a DO-35 glass axial-leaded package with cathode identified by a color band. The leads are tinned copper-clad steel, 0.46 mm in diameter and at least 25.4 mm long. This hermetically sealed package supports operation from -65°C to +200°C junction temperature.
What is the maximum power dissipation for the 1N6013B_T50R?
The 1N6013B_T50R is rated for 500 mW power dissipation at lead temperature (TL) ≤ 75°C. Above 75°C, power must be linearly derated at 4.0 mW/°C. This derating curve ensures safe operation up to the maximum junction temperature of +200°C under defined thermal conditions.
What is the Zener impedance of the 1N6013B_T50R at its test current?
The 1N6013B_T50R exhibits a Zener impedance (ZZ) of 95 Ω at the specified test current of 5 mA. This value reflects the dynamic resistance in reverse breakdown and directly impacts regulation accuracy under varying load currents in shunt regulator applications.
