Product details
Overview
1N5272BE3/TR from Microsemi is a 500 mW, 110 V nominal Zener diode in DO-35 glass axial-leaded package with ±5% voltage tolerance (B suffix), 1.1 mA test current, and 750 Ω dynamic impedance at 0.25 mA. It operates from −65 °C to +175 °C and regulates voltage in low-power reference and protection circuits for industrial power supplies.
For engineers reviewing the 1N5272BE3/TR datasheet, 1N5272BE3/TR pinout, 1N5272BE3/TR application, or 1N5272BE3/TR equivalent, key selection factors include Zener voltage stability over temperature, low leakage (<0.1 µA at 88 V), RoHS-compliant matte-tin plating, and tape-and-reel packaging for automated assembly.
Technical Context
This discrete Zener diode functions as a two-terminal voltage reference device, operating in reverse breakdown with cathode-banded polarity. Its regulation relies on controlled avalanche mechanism above 6 V, delivering stable 110 V output under 1.1 mA test current and maintaining <±0.110 %/°C temperature coefficient across −65 °C to +175 °C.
The DO-35 package provides hermetic glass sealing, 250 °C/W junction-to-lead thermal resistance at 10 mm lead length, and ESD insensitivity per MIL-STD-750 Method 1020. Forward voltage is ≤1.5 V at 200 mA, and capacitance remains minimal per Figure 2 of the datasheet.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5272B-TP (Micro Commercial) | Same 110 V ±5%, DO-35 package, but rated for 0.5 W at 75 °C ambient (derated vs. Microsemi's 25 °C base) | Limited to commercial-temp applications; not qualified to MIL-PRF-19500 screening levels | Select when cost sensitivity outweighs extended temperature or radiation requirements |
| MMBZ5272B (ON Semiconductor) | SMD MELF DO-213AA package, same 110 V ±5%, but 200 mW power rating and higher ZZK (1000 Ω) | Requires PCB rework for surface-mount assembly; unsuitable for through-hole legacy designs | Select only if board space constraints mandate SMD and 200 mW dissipation suffices |
Compared with 1N5272BE3/TR, the 1N5272B-TP offers identical electrical specs but lacks radiation hardness and extended temperature validation, while the MMBZ5272B trades power capability and through-hole compatibility for miniaturization-neither is pin-compatible nor drop-in.

FAQ
What is the Zener voltage tolerance for 1N5272BE3/TR?
The 1N5272BE3/TR has a nominal Zener voltage of 110 V with ±5% tolerance, confirmed by the "B" suffix per JEDEC specification. This means the actual measured VZ at 1.1 mA test current falls between 104.5 V and 115.5 V at 25 °C, and is guaranteed across the full operating temperature range.
Does 1N5272BE3/TR require heatsinking in typical applications?
No, the 1N5272BE3/TR does not require external heatsinking in standard applications. Its 500 mW power rating at 25 °C and 250 °C/W junction-to-lead thermal resistance allow safe operation up to 1.1 mA at ambient temperatures below 75 °C without added thermal mass, provided leads are trimmed to ≥10 mm from the glass body.
Is 1N5272BE3/TR suitable for space applications?
Yes, the 1N5272BE3/TR is inherently radiation-hardened per MicroNote 050 and qualifies for use in space applications. While not pre-screened to MIL-PRF-19500 JANS level, its base construction meets TID and SEE requirements typical for LEO missions when used within its rated electrical and thermal limits.
How does the "e3" and "TR" suffix affect 1N5272BE3/TR?
The "e3" suffix denotes RoHS-compliant matte-tin plating per EU Directive 2011/65/EU, replacing traditional tin-lead finish. The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated SMT placement. Both suffixes appear in the full orderable part number 1N5272BE3/TR and are integral to its compliance and manufacturability.
What is the maximum reverse leakage current for 1N5272BE3/TR?
The maximum reverse leakage current for 1N5272BE3/TR is 0.1 µA at 88 V (80% of nominal 110 V), as specified in the Electrical Characteristics table. This low leakage ensures minimal power loss in high-impedance bias networks and stable reference performance in precision analog circuits.
