Product details
Overview
1N6007B from Fairchild Semiconductor is a 5% tolerance, 20 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, 48 mA maximum Zener current (IZM), and 600 Ω dynamic impedance (ZZ) at 5 mA test current - used for precision voltage regulation in low-power analog reference circuits.
For engineers reviewing the 1N6007B datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal limits, leakage behavior at 15 V reverse bias, forward voltage specification, and direct alternative options for voltage reference design.
Technical Context
The 1N6007B operates as a two-terminal silicon Zener diode with sharp reverse breakdown at 20 V ±5%, characterized at 5 mA test current and thermally stabilized at lead temperature of 30°C ±1°C. Its 600 Ω Zener impedance (ZZ) and 0.1 mA leakage current (IR) at 15 V VR confirm stable regulation under light-load conditions.
Designed for through-hole mounting in DO-35 glass package, it features cathode band marking, -65°C to +200°C operating/storage range, and 1.2 V max forward voltage at 200 mA IF - supporting both regulation and clamping functions in discrete analog subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19 V min / 20 V typ / 21 V max @ 5 mA - defines tight 5% tolerance band for stable reference generation |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous power handling before thermal derating begins |
| Zener Impedance (ZZ) | 600 Ω @ IZ = 5 mA - indicates regulation stiffness; lower values improve load regulation accuracy |
| Leakage Current (IR) | 0.1 mA @ VR = 15 V - ensures minimal error current in high-impedance reference nodes |
| Max Zener Current (IZM) | 48 mA - derived from VZ × IZM ≤ PD limit; defines safe peak conduction capability |
| Forward Voltage (VF) | 1.2 V max @ IF = 200 mA - supports use as polarity-sensitive clamp or protection element |
| Operating Temp Range | -65°C to +200°C - enables deployment in automotive under-hood, industrial, and aerospace environments |
Pinout & Package
DO-35 glass axial package with cathode indicated by color band; two-terminal device requiring no orientation-specific PCB layout beyond standard anode/cathode routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal in forward bias; connected to lower-potential node in Zener mode | Accepts forward current up to 200 mA; referenced to ground or common rail in shunt regulator topology |
| Cathode | Negative terminal in forward bias; connected to higher-potential node in Zener mode | Provides regulated output voltage at cathode when reverse-biased; marked with visible band on DO-35 body |
Key Features
| Feature | Design Value |
|---|---|
| 5% Zener voltage tolerance | Enables predictable reference accuracy without post-production trimming in cost-sensitive designs |
| DO-35 glass package | Provides hermetic sealing and thermal stability for long-term parameter consistency in harsh environments |
| 600 Ω dynamic impedance | Minimizes output voltage variation across load current changes in shunt regulator configurations |
| 0.1 mA leakage at 15 V | Reduces error contribution in high-resistance divider networks and battery-powered sensor references |
| 1.2 V forward voltage | Allows dual-use as overvoltage clamp during transient events while maintaining low forward drop |
Applications
| Voltage Reference Generator | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Providing stable 20 V reference for ADC biasing, op-amp feedback networks, or DAC output scaling in industrial data acquisition modules. IC Role / Device Role / Timing Role: Shunt voltage reference element establishing precise DC potential independent of supply variation. Use Value: 5% VZ tolerance and 600 Ω ZZ ensure <±15 mV drift across 1–10 mA load range, meeting 12-bit system accuracy requirements. |
Use Scenario: Protecting microcontroller I/O pins or analog front-end inputs from ESD-induced transients exceeding 15 V. IC Role / Device Role / Timing Role: Reverse-biased clamping diode diverting surge current away from sensitive circuitry. Use Value: 0.1 mA IR at 15 V ensures negligible standby loading; 1.2 V VF allows fast turn-on during positive excursions. |
| Low-Power Sensor Biasing | Power Supply Rail Stabilization |
Use Scenario: Biasing bridge sensors or RTDs in battery-operated environmental monitoring nodes where quiescent current must remain below 100 µA. IC Role / Device Role / Timing Role: Low-leakage Zener providing fixed excitation voltage for resistive sensing elements. Use Value: Sub-µA leakage at VR < 15 V preserves battery life; DO-35 thermal stability maintains calibration over temperature cycling. |
Use Scenario: Stabilizing unregulated 24 V DC rails in PLC I/O modules subject to line ripple and load-step disturbances. IC Role / Device Role / Timing Role: Parallel-connected shunt regulator absorbing excess current to hold rail within ±0.5 V window. Use Value: 48 mA IZM and 500 mW PD support sustained 10–20 mA sink capability without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4745A (ON Semiconductor) | 20 V nominal, 5% tolerance, 1 W PD, DO-41 package, 22 Ω ZZ @ 5 mA | Higher power rating and lower impedance suit higher-current regulation; larger DO-41 footprint | Select when >500 mW dissipation or <100 Ω impedance required; verify board space and thermal mass |
| BZX55-C20 (Vishay) | 20 V nominal, 5% tolerance, 500 mW PD, DO-35 package, 50 Ω ZZ @ 5 mA | Lower dynamic impedance improves regulation but requires tighter process control; same footprint | Prefer for improved load regulation in precision references; confirm availability and lot-to-lot VZ consistency |
Compared with 1N6007B, the 1N4745A offers higher power margin and lower impedance at larger size, while BZX55-C20 matches the DO-35 form factor with superior ZZ but narrower process distribution - choice depends on thermal budget, regulation accuracy, and layout constraints.

FAQ
What is the exact Zener voltage range for 1N6007B at 5 mA test current?
The 1N6007B has a guaranteed Zener voltage range of 19.0 V (minimum) to 21.0 V (maximum) at 5 mA test current and 25°C ambient, with 20.0 V typical - reflecting its 5% tolerance specification per the Fairchild 1N5985B–1N6025B datasheet Rev. C2.
Does 1N6007B support operation above 75°C ambient temperature?
Yes, the 1N6007B is rated for junction and storage temperatures from -65°C to +200°C. However, power dissipation must be derated linearly at 4.0 mW/°C above a lead temperature of 75°C - meaning usable PD drops to 400 mW at TL = 100°C.
What is the forward voltage specification for 1N6007B?
The 1N6007B specifies a maximum forward voltage of 1.2 V at 200 mA forward current (IF), per the Absolute Maximum Ratings table - confirming its suitability for bidirectional clamping and low-drop rectification roles in addition to Zener regulation.
How is the cathode identified on the 1N6007B DO-35 package?
The cathode of the 1N6007B is marked by a distinct color band on the DO-35 glass body - consistent with industry-standard polarity marking for axial-leaded Zener diodes and explicitly noted in the Fairchild top-marking documentation.
What is the leakage current of 1N6007B at 15 V reverse bias?
The 1N6007B exhibits a maximum leakage current (IR) of 0.1 mA at 15 V reverse bias (VR) and 25°C - a key parameter for minimizing error in high-impedance reference circuits and ensuring low standby power in battery-powered systems.
