Product details
Overview
1N6007B_T50A 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, designed for precision voltage regulation and reference applications in industrial power supplies and analog signal conditioning circuits.
For engineers reviewing the 1N6007B_T50A datasheet, pinout, applications, or equivalent options, key selection criteria include verified Zener voltage (19–21 V), low dynamic impedance (600 Ω @ 5 mA), leakage current (≤0.1 mA @ 15 V), maximum Zener current (48 mA), and DO-35 thermal performance under lead-length-constrained PCB layouts.
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and temperature conditions. Its 20 V nominal Zener voltage is specified at 5 mA test current, with typical Zener impedance of 600 Ω and knee impedance of 600 Ω at 250 µA - indicating consistent regulation behavior across operating range.
The device features a DO-35 axial glass package with cathode band marking, rated for junction and storage temperatures from –65°C to +200°C, and exhibits forward voltage ≤1.2 V at 200 mA - enabling bidirectional circuit protection and dual-mode use in clamping or reference topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19–21 V @ 5 mA - defines precise regulation window for 20 V rail stabilization |
| Power Dissipation (PD) | 500 mW @ TL ≤ 75°C - sets maximum continuous thermal load on 3/8″ leads |
| Zener Impedance (ZZ) | 600 Ω @ 5 mA - determines output voltage variation under load current changes |
| Leakage Current (IR) | ≤0.1 mA @ 15 V - ensures minimal quiescent current draw in high-impedance bias networks |
| Max Zener Current (IZM) | 48 mA - establishes absolute current limit before thermal runaway at rated voltage |
| Operating Temp Range | –65°C to +200°C - supports deployment in automotive under-hood and industrial motor-control environments |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4745A (ON Semiconductor) | 20 V nominal, 5% tolerance, DO-41 package, 1 W rating, 20 Ω ZZ @ 25 mA | Higher power handling but larger footprint; requires layout revision for lead spacing | Select when >500 mW continuous dissipation or lower dynamic impedance is required |
| BZX55C20 (Vishay) | 20 V nominal, 5% tolerance, DO-35 package, 500 mW rating, 70 Ω ZZ @ 5 mA | Lower ZZ improves regulation but tighter VZ binning increases cost | Select when improved load regulation (<5 mV deviation) justifies premium pricing |
Compared with 1N6007B_T50A, the 1N4745A offers higher power margin at the expense of board space, while the BZX55C20 delivers superior dynamic regulation in the same DO-35 form factor but with stricter binning and cost trade-offs.

FAQ
What is the exact Zener voltage range for 1N6007B_T50A at 5 mA test current?
The 1N6007B_T50A has a guaranteed Zener voltage range of 19.0 V to 21.0 V when measured at 5 mA test current and lead temperature of 30°C ±1°C with 3/8″ lead length, per Fairchild's Rev. C2 datasheet. This 5% tolerance window reflects the device's specification as a general-purpose precision reference diode, not a trimmed or binned variant.
Is 1N6007B_T50A compatible with automated through-hole assembly processes?
Yes, the 1N6007B_T50A uses a standard DO-35 axial glass package with 0.4–0.6 mm lead diameter and 2.5–3.5 mm body diameter, fully compatible with industry-standard wave soldering, selective soldering, and hand-soldering processes. Its cathode band marking is machine-readable for AOI verification in high-volume manufacturing lines.
Does 1N6007B_T50A meet RoHS requirements?
The 1N6007B_T50A is RoHS-compliant per Fairchild Semiconductor's product change notices and material declarations. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and conforms to EU Directive 2011/65/EU as shipped in original factory packaging.
What is the maximum allowable ambient temperature for continuous operation of 1N6007B_T50A?
The 1N6007B_T50A has a storage and operating junction temperature range of –65°C to +200°C, but continuous ambient temperature must be limited by power derating: at 75°C lead temperature, full 500 mW is allowed; above that, power must be reduced by 4.0 mW/°C. For typical PCB mounting, ambient temperature should not exceed ~60°C to maintain safe junction temperature margins.
Can 1N6007B_T50A be used in series or parallel configurations for higher voltage or current handling?
1N6007B_T50A may be used in series to achieve higher reference voltages (e.g., two units for ~40 V), but parallel connection is not recommended due to mismatched Zener impedances causing current hogging. For higher current, external series resistors or active current-sharing circuits are required - the device itself is rated for 48 mA maximum Zener current.
