Product details
Overview
1N3016BE3 from Microsemi is a hermetically sealed, metallurgically bonded DO-41 glass-case Zener diode with nominal 6.8 V zener voltage at 37 mA test current, 1.0 W power dissipation, ±5% voltage tolerance (B suffix), and RoHS-compliant matte tin plating. It operates across –55 °C to +175 °C and delivers low reverse leakage (≤1.0 mA at 5.2 V) for precision voltage regulation in high-reliability analog power supplies.
For engineers reviewing the 1N3016BE3 datasheet, 1N3016BE3 pinout, 1N3016BE3 application, or 1N3016BE3 equivalent, key selection criteria include its MIL-PRF-19500/115 qualification level (commercial e3 variant), DO-41 mechanical robustness, 80 °C/W junction-to-lead thermal resistance, and verified performance under thermal cycling and radiation-hardened conditions per MicroNote 050.
Technical Context
This device functions as a two-terminal voltage reference operating in reverse breakdown, where zener voltage is stabilized by avalanche and/or zener mechanisms depending on the 6.8 V rating. Its double-plug construction and tungsten slugs ensure mechanical integrity and thermal stability under sustained 1 W dissipation at lead temperature ≤65 °C.
The 1N3016BE3 exhibits 3.5 Ω dynamic impedance (ZZT) at IZT = 37 mA and 700 Ω knee impedance (ZZK) near IZK, enabling stable regulation across wide load current variations. Its non-ESD-sensitive design and inherent radiation hardness support deployment in aerospace, defense, and industrial control systems requiring long-term parametric stability.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4734A | 6.8 V ±5%, 1.0 W, DO-41, but non-hermetic epoxy package and no MIL qualification | Limited to commercial-grade industrial equipment; not suitable for aerospace or radiation environments | Select when cost sensitivity outweighs reliability requirements and hermeticity is unnecessary |
| BZX55C6V8 | 6.8 V ±5%, 500 mW, DO-35 glass package, RoHS-compliant, no military screening | Lower power handling restricts use to low-current references; lacks MIL-PRF-19500 validation | Choose only for space-constrained PCBs where 1 W dissipation is not required |
Compared with 1N3016BE3, the 1N4734A offers identical electrical specs but sacrifices hermetic sealing and military reliability screening, while the BZX55C6V8 reduces power capability by 50% and omits radiation hardness-making the 1N3016BE3 the sole choice for mission-critical, high-stability, high-power Zener regulation.

FAQ
What is the Zener voltage tolerance and test current for the 1N3016BE3?
The 1N3016BE3 has a nominal Zener voltage of 6.8 V with ±5% tolerance (denoted by the "B" in the part number) and is specified at a test current IZT of 37 mA. This ensures stable regulation under typical shunt reference operating conditions and aligns with JEDEC standard 1N3016B-1 characterization.
Is the 1N3016BE3 suitable for high-reliability aerospace applications?
Yes-the 1N3016BE3 is manufactured to MIL-PRF-19500/115 specifications and qualified to commercial (e3) level with hermetic glass packaging, metallurgical bonding, and documented radiation hardness per MicroNote 050. While full JAN/JANTXV variants exist, the 1N3016BE3 retains core reliability features essential for aerospace subsystems.
What is the maximum reverse leakage current for the 1N3016BE3 and at what voltage is it measured?
The 1N3016BE3 has a maximum reverse leakage current (IR) of 1.0 mA, measured at VR = 5.2 V (75% of nominal VZ). This low leakage supports high-impedance bias networks and precision reference circuits where standby current must remain tightly bounded.
Does the 1N3016BE3 have RoHS compliance, and how is it indicated in the part number?
Yes-the "e3" suffix in 1N3016BE3 explicitly denotes RoHS-compliant matte tin plating over copper leads, per Microsemi's commercial-grade offering. This version meets EU RoHS Directive 2011/65/EU and is distinct from non-RoHS variants lacking the "e3" designation.
How does the thermal resistance of the 1N3016BE3 affect its power derating in real-world PCB layouts?
The 1N3016BE3 has a junction-to-lead thermal resistance (RθJL) of 80 °C/W. When mounted on FR4 with 3/8″ (10 mm) lead length, its DC power dissipation must be linearly derated from 1.0 W at +65 °C lead temperature to zero at +175 °C-requiring thermal design attention in enclosed or high-ambient environments.
