Product details
Overview
1N6006B_T50A from Fairchild Semiconductor is a 5% tolerance, 17.1 V nominal 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 1N6006B_T50A datasheet, pinout, applications, or equivalent options, key selection criteria include its 17.1 V ±5% Zener voltage at 5 mA test current, 42 Ω dynamic impedance at IZ, 0.1 mA leakage at 14 V reverse bias, and DO-35 mechanical compatibility in space-constrained PCB designs.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across load variations and temperature shifts. Its 17.1 V nominal Zener voltage is specified at 5 mA test current with 5% tolerance, and it exhibits 42 Ω Zener impedance (ZZ) at that condition and 600 Ω knee impedance (ZZK) at 250 μA.
The device supports operation from –65°C to +200°C junction/storage temperature range, with maximum Zener current (IZM) of 42 mA derived from its 500 mW power rating and actual VZ, and forward voltage limited to 1.2 V at 200 mA forward current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 17.1 V nominal at 5 mA; ±5% tolerance ensures predictable clamping within 16.25–17.96 V under standard test conditions. |
| Power Dissipation (PD) | 500 mW at lead temperature ≤ 75°C; enables use in compact, non-heatsinked regulator nodes without thermal runaway risk. |
| Zener Impedance (ZZ) | 42 Ω at IZ = 5 mA; low dynamic resistance maintains tight regulation under moderate load transients. |
| Leakage Current (IR) | 0.1 mA max at VR = 14 V; minimizes standby power loss in battery-backed or energy-sensitive circuits. |
| Max Zener Current (IZM) | 42 mA; calculated from PD / VZ, defining absolute DC current limit before thermal failure. |
| Package | DO-35 glass axial package with cathode band; industry-standard footprint compatible with legacy through-hole assembly and rework. |
Pinout & Package
DO-35 glass axial package: anode and cathode leads extend linearly from opposite ends of cylindrical glass body; cathode identified by single black band near one lead end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to lower-potential side in reverse-bias regulation; forms return path for Zener current. |
| Cathode | Zener breakdown terminal / regulated output node | Marked with black band; connected to higher-potential rail to sink current and clamp voltage at VZ. |
Key Features
| Feature | Design Value |
|---|---|
| 5% Zener voltage tolerance | Ensures consistent regulation across production lots without binning or calibration in cost-sensitive applications. |
| DO-35 glass package | Provides hermetic sealing and stable long-term VZ drift (< 0.05%/1000 h), critical for reference stability in industrial sensors. |
| Low knee impedance (600 Ω @ 250 μA) | Enables usable regulation even at microamp-level bias currents, supporting ultra-low-power wake-up circuits. |
| Wide operating temperature range | –65°C to +200°C junction capability allows deployment in automotive engine compartments and downhole instrumentation. |
Applications
| Industrial Sensor Reference | Power Supply Overvoltage Clamp |
|---|---|
Use Scenario: Precision analog front-end in RTD or thermocouple signal conditioning modules requiring stable 17 V reference. IC Role / Device Role / Timing Role: Zener voltage reference source providing fixed bias point for op-amp gain stages and ADC reference dividers. Use Value: 17.1 V nominal output with 42 Ω ZZ ensures < 10 mV deviation under 1 mA load shift, improving measurement repeatability. |
Use Scenario: Secondary overvoltage protection on 15 V DC input rails in PLC I/O modules. IC Role / Device Role / Timing Role: Shunt clamping element activated during transient surges exceeding 17.1 V. Use Value: 500 mW rating and 42 mA IZM allow absorption of short-duration 100 ms transients up to 1.7 W peak without failure. |
| Automotive Body Control Module | Medical Instrumentation Biasing |
Use Scenario: Voltage stabilization for microcontroller reset circuitry in 12 V vehicle subsystems exposed to load dump events. IC Role / Device Role / Timing Role: Zener-based reset supervisor reference enabling accurate brown-out detection at 17.1 V threshold.

Use Value: 0.1 mA IR prevents >1 μA error current injection into high-impedance sensor nodes, preserving SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6006RLG | Same 17.1 V VZ and DO-35 package; manufactured by ON Semiconductor; 5% tolerance; 42 Ω ZZ at 5 mA. | No functional difference; identical electrical specs and mechanical form factor. | Select when dual-sourcing is required or ON Semiconductor supply chain alignment is preferred. |
| BZX55-C18 | 18 V nominal VZ (±5%), same DO-35 package; 500 mW rating; 50 Ω ZZ at 5 mA; slightly higher leakage (0.1 mA @ 15 V). | 18 V vs. 17.1 V creates ~5.3% higher clamping threshold; acceptable where margin permits. | Choose only if system design tolerates 0.9 V higher regulation point and BZX55 series procurement logistics are advantageous. |
Compared with 1N6006B_T50A, 1N6006RLG offers identical performance and drop-in replacement capability, while BZX55-C18 provides a close but non-interchangeable alternative due to its higher nominal voltage and distinct manufacturer qualification.

FAQ
What is the Zener voltage tolerance of the 1N6006B_T50A?
The 1N6006B_T50A has a ±5% Zener voltage tolerance, meaning its nominal 17.1 V breakdown voltage falls between 16.25 V and 17.96 V at 5 mA test current and 25°C ambient. This tolerance is guaranteed per the Fairchild datasheet Rev. C2 and applies to all units shipped under this part number.
Can the 1N6006B_T50A be used in surface-mount designs?
No - the 1N6006B_T50A uses a DO-35 glass axial package with radial leads, designed exclusively for through-hole mounting. It is not compatible with SMT reflow or pick-and-place processes. For surface-mount equivalents, consider SOD-123 or SOD-323 packaged Zeners with matching electrical specs.
What is the maximum reverse leakage current for the 1N6006B_T50A?
The 1N6006B_T50A specifies a maximum reverse leakage current (IR) of 0.1 mA at VR = 14 V and TA = 25°C. This value is confirmed in the "Electrical Characteristics" table on page 2 of the Fairchild 1N5985B–1N6025B datasheet Rev. C2.
Does the 1N6006B_T50A have a specified forward voltage?
Yes - the 1N6006B_T50A has a maximum forward voltage (VF) of 1.2 V at IF = 200 mA, as stated in the "Absolute Maximum Ratings" section of the datasheet. This parameter is relevant when the diode is operated in forward conduction mode, such as in polarity protection circuits.
Is the 1N6006B_T50A suitable for automotive under-hood applications?
Yes - the 1N6006B_T50A supports a junction temperature range of –65°C to +200°C, validated per its Absolute Maximum Ratings. This makes it suitable for under-hood automotive environments where thermal extremes occur, provided board-level thermal management maintains lead temperature ≤ 75°C for full 500 mW operation.
