Product details
Overview
1N6005B_T50A from Fairchild Semiconductor is a 15.2 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, 36 mA maximum Zener current (IZM), and 15 Ω typical Zener impedance (ZZ) at 5 mA test current - used for precision voltage regulation and reference in low-power analog circuits.
For engineers reviewing the 1N6005B_T50A datasheet, pinout, applications, or equivalent options, key selection criteria include Zener voltage tolerance, thermal derating behavior, leakage current at 12 V reverse bias (0.1 mA), and DO-35 mechanical compatibility in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal VZ of 15.2 V (min 15.0 V, max 15.75 V) at IZ = 5 mA, exhibiting 15 Ω dynamic impedance (ZZ) and 600 Ω knee impedance (ZZK) at IZK = 250 μA. Its 0.1 mA leakage current at VR = 12 V ensures low standby power loss in bias networks.
The device is specified for operation across –65°C to +200°C junction and storage temperature range, with forward voltage limited to 1.2 V max at IF = 200 mA - confirming suitability for bidirectional protection and clamping roles where forward conduction may occur transiently.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15.2 V min–max range (15.0–15.75 V) at 5 mA - defines stable regulation point for feedback references. |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous power handling before thermal derating applies. |
| Zener Impedance (ZZ) | 15 Ω typical @ IZ = 5 mA - indicates low AC impedance for stable voltage under varying load conditions. |
| Leakage Current (IR) | 0.1 mA @ VR = 12 V - confirms minimal current draw below breakdown, critical for battery-powered circuits. |
| Max Zener Current (IZM) | 36 mA - derived from VZ × IZM ≤ PD limit; defines peak steady-state current capability. |
| Operating Temp Range | –65°C to +200°C - supports deployment in automotive under-hood and industrial high-temp environments. |
| Forward Voltage (VF) | 1.2 V max @ IF = 200 mA - enables use as low-drop clamp or polarity protection element. |
Pinout & Package
DO-35 glass axial package with cathode indicated by color band; two-terminal device requiring no orientation-specific PCB footprint beyond standard axial lead spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Cathode | Reference output node | Provides stable 15.2 V relative to anode; marked by color band per JEDEC DO-35 standard. |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Enables predictable regulation without post-production trimming in cost-sensitive consumer power supplies. |

Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Stabilizing feedback voltage in linear regulator ICs or discrete op-amp-based regulators. IC Role / Device Role / Timing Role: Voltage reference element defining output setpoint accuracy and load regulation. Use Value: 15.2 V ±5% tolerance and 15 Ω ZZ maintain <1% output variation across 1–10 mA load changes. |
Use Scenario: Protecting ADC inputs or microcontroller GPIO pins from transient overvoltage events. IC Role / Device Role / Timing Role: Shunt clamping device diverting excess energy to ground above 15.2 V. Use Value: 36 mA IZM and 0.1 mA IR at 12 V ensure fast response with negligible standby leakage. |
| Bias Network Stabilizer | Temperature-Compensated Oscillator Core |
Use Scenario: Setting precise quiescent current in Class-A amplifier stages or sensor excitation circuits. IC Role / Device Role / Timing Role: Stable DC reference source for current mirror or voltage divider biasing. Use Value: –65°C to +200°C operating range maintains bias stability across automotive ambient extremes. |
Use Scenario: Providing fixed reference voltage in RC relaxation oscillators where frequency stability depends on VZ consistency.

Use Value: Low ZZ and tight VZ tolerance reduce frequency drift vs. supply or temperature variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4744A | 14 V nominal VZ, 1 W PD, DO-41 package - higher power but looser 5% tolerance and larger footprint. | Preferred for higher-current regulation (>50 mA) where thermal margin is critical; not DO-35 compatible. | Select when board layout allows DO-41 and >500 mW dissipation is required. |
| BZX55-C15 | 15 V nominal VZ, ±5% tolerance, 500 mW, DO-35 - identical electrical specs but different marking and traceability chain. | Drop-in replacement in legacy designs using BZX55 series; same thermal and mechanical behavior. | Choose for cross-manufacturer sourcing continuity where Fairchild supply is constrained. |
Compared with 1N6005B_T50A, the 1N4744A offers higher power but requires PCB redesign, while the BZX55-C15 provides identical regulation performance in the same DO-35 form factor with alternate logistics traceability.

FAQ
What is the Zener voltage tolerance of the 1N6005B_T50A?
The 1N6005B_T50A has a ±5% Zener voltage tolerance, meaning its breakdown voltage ranges from 15.0 V to 15.75 V at the specified 5 mA test current. This tolerance is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the Fairchild 1N5985B–1N6025B datasheet Rev. C2. The 1N6005B_T50A maintains this specification across its full operating temperature range.
Can the 1N6005B_T50A be used in high-temperature environments?
Yes, the 1N6005B_T50A is rated for junction and storage temperatures from –65°C to +200°C, making it suitable for under-hood automotive, industrial motor controls, and downhole instrumentation. Its DO-35 glass package contributes to thermal stability, and the 1N6005B_T50A retains specified Zener characteristics across this full range per the manufacturer's characterization data.
What is the maximum Zener current (IZM) for the 1N6005B_T50A?
The maximum Zener current (IZM) for the 1N6005B_T50A is 36 mA, calculated based on its 15.2 V nominal Zener voltage and 500 mW power rating at TL ≤ 75°C. This value is explicitly listed in the Electrical Characteristics table for the 1N6005B_T50A row. Exceeding 36 mA risks exceeding the device's thermal limits unless derated per the 4.0 mW/°C curve.
Does the 1N6005B_T50A have a specified forward voltage?
Yes, the 1N6005B_T50A has a maximum forward voltage (VF) of 1.2 V at 200 mA forward current, as stated in the "VF Forward Voltage" note on page 3 of the Fairchild datasheet. This parameter confirms the 1N6005B_T50A can serve dual roles - Zener regulation in reverse bias and low-drop clamping or protection in forward conduction - without excessive voltage loss.
Is the 1N6005B_T50A available in tape-and-reel packaging for automated assembly?
Yes, the 1N6005B_T50A is supplied in tape-and-reel format compliant with EIA-481 standards for surface-mount placement equipment, as well as bulk and ammo-pack options. Aetrix Electronics stocks the 1N6005B_T50A in 10,000-piece reels, supporting high-volume SMT production lines without manual handling or feeding issues specific to axial DO-35 devices.
