Product details
Overview
1N6001B_T50R from Fairchild Semiconductor is a 5% tolerance, 11 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, designed for precision voltage regulation and reference applications in industrial power supplies and analog signal conditioning circuits.
For engineers reviewing the 1N6001B_T50R datasheet, pinout, applications, or equivalent options, this page delivers verified Zener voltage (10.45–11.55 V), test current (5 mA), zener impedance (18 Ω @ IZ), leakage current (0.1 mA @ 8.4 V), and thermal operating range (–65 to +200°C) - all confirmed from Fairchild's official Rev. C2 specification.
Technical Context
The 1N6001B_T50R operates as a silicon planar Zener diode with sharp reverse breakdown at nominal 11 V, characterized under thermal equilibrium at lead temperature TL = 30°C ± 1°C and 3/8″ lead length. Its design targets stable DC voltage reference generation where low dynamic impedance and tight voltage tolerance are critical.
Zener impedance is specified at 18 Ω measured at 5 mA test current (IZ), and knee impedance ZZK is 600 Ω at IZK = 250 μA. Leakage current remains ≤0.1 mA up to 8.4 V reverse bias, supporting reliable clamping and reference stability in low-power analog subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 10.45–11.55 V at 5 mA - defines precise regulation window for 11 V reference designs |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous thermal load on PCB traces and heatsinking |
| Zener Impedance (ZZ) | 18 Ω @ IZ = 5 mA - ensures minimal output voltage variation under load current changes |
| Leakage Current (IR) | ≤0.1 mA @ VR = 8.4 V - guarantees low standby power loss and high off-state blocking integrity |
| Operating Temperature | –65 to +200°C - enables deployment in extended-temperature industrial and automotive under-hood environments |
| Forward Voltage (VF) | ≤1.2 V @ IF = 200 mA - supports bidirectional protection use cases when forward-biased |
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 |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4740A | 10 V nominal, 5% tolerance, DO-41 package, 1.0 W rating | Higher power handling but larger footprint; less suitable for space-constrained PCBs | Select when >500 mW dissipation or higher surge energy absorption is required |
| BZX55C11 | 11 V nominal, 5% tolerance, DO-35 package, 500 mW rating, 20 Ω ZZ | Nearly identical electrical specs; different marking and minor process variation | Choose for second-source availability with same board layout and thermal profile |
Compared with 1N4740A and BZX55C11, the 1N6001B_T50R offers identical DO-35 form factor and thermal envelope as BZX55C11 but tighter production consistency per Fairchild's legacy process, while differing from 1N4740A in both package size and power class - making it optimal for compact, thermally constrained 11 V reference nodes.

FAQ
What is the exact Zener voltage range for 1N6001B_T50R at 5 mA test current?
The 1N6001B_T50R has a guaranteed Zener voltage range of 10.45 V (minimum) to 11.55 V (maximum) when tested at 5 mA, per Fairchild's Rev. C2 datasheet. This 5% tolerance window reflects the device's nominal 11 V rating and ensures predictable performance in voltage reference circuits without calibration.
Does 1N6001B_T50R support operation above 100°C ambient temperature?
Yes, the 1N6001B_T50R is rated for junction and storage temperatures from –65°C to +200°C. Its thermal design allows operation in high-ambient environments such as motor drive cabinets or power supply enclosures, provided lead temperature stays ≤75°C for full 500 mW power dissipation - derating linearly beyond that point.
What is the maximum reverse leakage current for 1N6001B_T50R, and at what voltage is it specified?
The maximum reverse leakage current for 1N6001B_T50R is 0.1 mA, specified at a reverse voltage (VR) of 8.4 V. This low leakage ensures minimal parasitic current draw in high-impedance reference or sensing nodes, preserving accuracy in battery-powered or precision analog systems.
Is the 1N6001B_T50R packaged in DO-35, and how is polarity marked?
Yes, the 1N6001B_T50R uses the DO-35 glass axial package. Polarity is marked by a single color band on the cathode end - consistent with industry-standard Zener diode marking. The anode is the unmarked lead, and correct orientation is essential for proper shunt regulation function.
How does the zener impedance of 1N6001B_T50R affect voltage regulation stability?
The 1N6001B_T50R exhibits 18 Ω zener impedance at 5 mA test current, meaning a ±1 mA change in load current produces only ±18 mV variation in regulated output voltage. This low dynamic impedance directly improves regulation accuracy in feedback loops and reduces sensitivity to supply ripple or load transients.
