Product details
Overview
1N6004B_T50A from Fairchild Semiconductor is a 15 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 1N6004B_T50A datasheet, pinout, applications, or equivalent options, key selection criteria include zener voltage tolerance (±5%), zener impedance (32 Ω @ 5 mA), leakage current (0.1 mA @ 11 V), and thermal stability across -65°C to +200°C operating range.
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable voltage under varying load and temperature conditions. Its 15 V nominal zener voltage is specified at 5 mA test current with ±5% tolerance, and it exhibits low dynamic impedance (32 Ω) ensuring tight regulation in feedback paths.
The device uses a DO-35 axial glass package with cathode band marking, supports lead temperature-based power derating (4.0 mW/°C above 75°C), and meets industrial-grade storage and junction temperature requirements (-65°C to +200°C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.25–15.75 V @ 5 mA - defines regulated output voltage window for reference design |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous power handling before thermal derating |
| Zener Impedance (ZZ) | 32 Ω @ IZ = 5 mA - determines voltage deviation under load current variation |
| Leakage Current (IR) | 0.1 mA @ VR = 11 V - ensures minimal error current in high-impedance bias networks |
| Operating Temp Range | -65°C to +200°C - enables use in automotive under-hood and industrial environments |
| Forward Voltage (VF) | 1.2 V max @ IF = 200 mA - supports basic polarity verification and ESD protection function |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A (ON Semiconductor) | 15 V, 5% tolerance, 1 W rating, DO-41 package, ZZ = 14 Ω @ 25 mA | Higher power handling but larger footprint and different test current (25 mA vs. 5 mA) | Select when higher surge current capability or improved regulation at higher currents is required |
| BZX55-C15 (Vishay) | 15 V, 5% tolerance, 500 mW, DO-35, ZZ = 30 Ω @ 5 mA, IR = 0.1 µA @ 11.4 V | Lower leakage (0.1 µA vs. 0.1 mA) but identical package and regulation specs | Prefer for ultra-low-power bias networks where leakage must be minimized below 1 µA |
Compared with 1N6004B_T50A, the 1N4744A offers better regulation at high current but requires PCB layout change due to DO-41 size, while BZX55-C15 matches form/fit/function but improves leakage by three orders of magnitude for battery-critical designs.

FAQ
What is the zener voltage tolerance of the 1N6004B_T50A?
The 1N6004B_T50A has a ±5% zener voltage tolerance, meaning its nominal 15 V breakdown voltage falls within 14.25 V to 15.75 V at 5 mA test current. This tolerance is guaranteed across the full operating temperature range and supports consistent performance in untrimmed reference circuits without requiring post-manufacture calibration.
What is the maximum zener current (IZM) for the 1N6004B_T50A?
The 1N6004B_T50A has a maximum zener current (IZM) of 33 mA, determined by its 500 mW power rating and 15.75 V upper zener voltage limit. This value is valid at lead temperature ≤ 75°C; above that, derating applies at 4.0 mW/°C, reducing usable IZM proportionally in elevated ambient conditions.
Does the 1N6004B_T50A have a specified forward voltage?
Yes, the 1N6004B_T50A specifies a maximum forward voltage (VF) of 1.2 V at 200 mA forward current. This parameter supports functional verification during in-circuit testing and confirms diode polarity integrity, though the device is intended for reverse-bias operation as a voltage reference or clamp.
What package type does the 1N6004B_T50A use?
The 1N6004B_T50A uses the DO-35 glass axial package, identified by a cathode band on the glass body. It features 3/8" lead length for thermal rating compliance and is compatible with standard through-hole assembly processes and wave soldering profiles defined for glass-body diodes.
How does the 1N6004B_T50A perform at high temperature?
The 1N6004B_T50A maintains full functionality across -65°C to +200°C junction temperature range. Its zener voltage exhibits predictable temperature coefficient behavior, and power dissipation remains stable up to 75°C lead temperature before linear derating begins-enabling deployment in under-hood automotive and industrial motor drive environments.
