Product details
Overview
1N6008B_T50A from Fairchild Semiconductor is a 22 V, 5% tolerance Zener diode in DO-35 glass package, rated for 500 mW power dissipation at TL ≤ 75°C with 4.0 mW/°C derating, used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the 1N6008B_T50A datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance (±5%), zener impedance (600 Ω @ 5 mA), leakage current (0.1 mA @ 17 V), and thermal stability across -65°C to +200°C operating range.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal zener voltage of 22 V at 5 mA test current, exhibiting typical zener impedance of 600 Ω and knee impedance of 600 Ω at 250 µA. Its DO-35 axial glass package enables through-hole mounting with cathode band identification.
The device maintains stable regulation over a wide temperature range (-65°C to +200°C) and supports maximum zener current of 55 mA under worst-case thermal conditions, with forward voltage limited to 1.2 V max at 200 mA forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum steady-state thermal load on PCB trace or heatsink |
| Zener Impedance (ZZ) | 600 Ω @ IZ = 5 mA - determines regulation sensitivity to load current changes |
| Leakage Current (IR) | 0.1 mA @ VR = 17 V - specifies off-state conduction limiting error in high-impedance bias networks |
| Operating Temperature | -65°C to +200°C - enables use in automotive under-hood, industrial control, and aerospace environments |
| Forward Voltage (VF) | 1.2 V max @ IF = 200 mA - ensures predictable clamping behavior during transient forward conduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6008RLG | Same 22 V nominal zener voltage, DO-35 package, but manufactured by ON Semiconductor with tighter 2% tolerance option available | Higher precision variants support metrology-grade references where ±2% tolerance is required | Select 1N6008RLG only if tighter voltage tolerance or alternate supply chain diversification is needed |
| BZX55C22 | 22 V Zener in DO-35, 5% tolerance, but rated for 500 mW at 25°C ambient (not lead-temperature referenced); higher leakage (0.5 µA @ 17 V) | Lower leakage makes 1N6008B_T50A preferable in ultra-low-power monitoring; BZX55C22 offers broader distributor availability | Choose 1N6008B_T50A for thermal-stable regulation in elevated ambient; choose BZX55C22 for general-purpose replacement where lead-temperature derating is not critical |
Compared with 1N6008RLG and BZX55C22, the 1N6008B_T50A delivers superior thermal derating behavior (4.0 mW/°C above 75°C lead temp) and lower leakage (0.1 mA vs. 0.5 µA), making it optimal for high-reliability industrial and automotive applications demanding stable regulation across wide temperature gradients.
