Product details
Overview
1N6000B_T50R from Fairchild Semiconductor is a 9.5–10.5 V, 5% tolerance, 500 mW DO-35 glass-case Zener diode optimized for precision voltage regulation and reference applications in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the 1N6000B_T50R datasheet, pinout, applications, or equivalent options, key selection criteria include its 15 Ω zener impedance at 5 mA, 0.1 mA leakage at 8 V reverse bias, 50 mA maximum zener current, and thermal stability across –65°C to +200°C operating range.
Technical Context
This Zener diode operates in reverse breakdown with tightly controlled voltage tolerance (±5%) and low dynamic impedance (15 Ω @ IZ = 5 mA), enabling stable reference generation under varying load and temperature conditions. Its DO-35 axial glass package supports manual soldering and high-reliability through-hole mounting.
The device exhibits 100% tested zener voltage at 5 mA test current, 0.1 mA leakage at VR = 8 V, and a forward voltage ≤1.2 V at 200 mA - confirming dual-direction functionality for clamping and bidirectional protection schemes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.5–10.5 V @ IZ = 5 mA - defines precise regulation window for feedback or reference use |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous power handling in standard leaded layout |
| Zener Impedance (ZZ) | 15 Ω @ IZ = 5 mA - ensures minimal output voltage variation under load transients |
| Leakage Current (IR) | 0.1 mA @ VR = 8 V - guarantees low standby power loss in high-impedance bias networks |
| Max Zener Current (IZM) | 50 mA - determines safe peak current limit before thermal runaway at rated voltage |
| Operating Temperature | –65°C to +200°C - supports deployment in automotive engine compartments and industrial control enclosures |
Pinout & Package
DO-35 glass axial package with cathode band marking; two-terminal device requiring no orientation-specific PCB footprint beyond standard 0.4" lead spacing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reverse breakdown reference ground node | Connected to circuit ground or lower-potential rail during Zener operation |
| Cathode | Reverse-biased voltage reference output / Forward anode counterpart | Delivers regulated voltage when reverse biased; marked by color band on DO-35 body |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Enables single-part qualification for mid-precision reference needs without trimming |
| 15 Ω dynamic impedance @ 5 mA | Maintains < ±25 mV regulation shift across 1–10 mA load changes |
| 0.1 mA leakage @ 8 V | Reduces error contribution in high-resistance divider networks (e.g., >1 MΩ) |
| DO-35 glass package | Provides hermetic sealing and long-term parameter stability in humid environments |
| –65°C to +200°C operating range | Eliminates derating concerns in under-hood or furnace-controller applications |
Applications
| Power Supply Feedback | Overvoltage Clamp |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or buck-derived DC/DC converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Precision voltage reference element setting error amplifier trip point. Use Value: 9.5–10.5 V range aligns with TL431-compatible feedback thresholds while offering lower cost and higher temperature resilience than IC references. |
Use Scenario: Protecting microcontroller I/O pins or ADC inputs from transient surges exceeding 8 V. IC Role / Device Role / Timing Role: Bidirectional voltage clamp limiting both positive overvoltage and negative ESD events. Use Value: 0.1 mA leakage preserves signal integrity in high-impedance sensor interfaces; 1.2 V forward drop enables effective negative swing suppression. |
| Voltage Reference | Current Source Bias |
Use Scenario: Generating stable bias for op-amp comparators or transistor current mirrors in battery-powered instrumentation. IC Role / Device Role / Timing Role: Low-drift, low-noise DC reference node independent of supply rail fluctuations. Use Value: 15 Ω impedance minimizes noise coupling into sensitive analog nodes; DO-35 package avoids PCB thermal gradients affecting reference accuracy. |
Use Scenario: Setting constant current for LED drivers or sensor excitation circuits using resistor-Zener combinations. IC Role / Device Role / Timing Role: Stable voltage source defining current through series sense resistor. Use Value: Tight 5% tolerance ensures ±5% current accuracy without calibration; 500 mW rating supports ≥10 mA drive capability at 10 V. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4739A (ON Semiconductor) | 10 V nominal, 5% tolerance, 1000 mW rating, DO-41 package | Higher power handling but larger footprint; less suitable for space-constrained DO-35 layouts | Select when >500 mW dissipation or legacy DO-41 board compatibility is required |
| BZX55C10 (Vishay) | 10 V nominal, 5% tolerance, 500 mW, DO-35 package, 20 Ω ZZ | Slightly higher dynamic impedance reduces regulation tightness under fast load steps | Prefer for cost-sensitive volume production where 15 → 20 Ω ZZ shift is acceptable |
Compared with 1N6000B_T50R, the 1N4739A offers double the power rating but requires PCB redesign for DO-41; the BZX55C10 matches the DO-35 form factor but trades 5 Ω higher impedance for broader vendor availability.

FAQ
What is the nominal Zener voltage of the 1N6000B_T50R?
The 1N6000B_T50R has a nominal Zener voltage of 10 V, with a guaranteed range of 9.5 V to 10.5 V at 5 mA test current and ±5% tolerance. This specification is verified per Fairchild's 1N5985B–1N6025B datasheet Rev. C2, ensuring predictable regulation behavior in feedback and reference circuits where the 1N6000B_T50R is deployed.
Does the 1N6000B_T50R have a specified forward voltage?
Yes, the 1N6000B_T50R has a maximum forward voltage of 1.2 V at 200 mA forward current, as stated in the Absolute Maximum Ratings table of the official datasheet. This characteristic supports its use as a bidirectional clamp, and confirms that the 1N6000B_T50R can safely conduct reverse surge energy while maintaining low forward drop during polarity-reversal events.
What is the Zener impedance of the 1N6000B_T50R and why does it matter?
The 1N6000B_T50R exhibits a Zener impedance (ZZ) of 15 Ω at 5 mA test current. This low dynamic impedance means the 1N6000B_T50R maintains tight voltage regulation - typically within ±25 mV - across load current variations from 1 mA to 10 mA, making it suitable for precision analog references where the 1N6000B_T50R replaces more complex IC solutions.
Is the 1N6000B_T50R suitable for high-temperature environments?
Yes, the 1N6000B_T50R is rated for operation from –65°C to +200°C, with no derating required up to +75°C at the lead temperature. Its DO-35 glass package and silicon construction ensure stable Zener voltage and leakage performance in under-hood automotive modules or industrial motor controllers where the 1N6000B_T50R serves as a ruggedized reference element.
How is the cathode identified on the 1N6000B_T50R package?
The cathode of the 1N6000B_T50R is marked by a distinct color band on the DO-35 glass body, consistent with industry-standard polarity identification. This band must be oriented toward the higher-potential node in reverse-bias Zener operation, and aligns with the cathode symbol in all official Fairchild schematics and layout guidelines for the 1N6000B_T50R.
