Product details
Overview
1N5274BE3/TR from Microsemi is a 130 V, ±5% tolerance, 500 mW glass axial-lead Zener diode in DO-35 (DO-204AH) package, rated for 0.95 mA test current and 4500 Ω maximum Zener impedance at 0.25 mA, used for precision voltage regulation in power supply reference circuits.
For engineers reviewing the 1N5274BE3/TR datasheet, 1N5274BE3/TR pinout, 1N5274BE3/TR application, or 1N5274BE3/TR equivalent, this page delivers verified electrical specs, thermal derating behavior, temperature coefficient (+0.110 %/°C), RoHS-compliant plating, and tape-and-reel packaging details critical for high-reliability industrial and aerospace designs.
Technical Context
This Zener operates in reverse breakdown with cathode band indicating polarity; it maintains stable 130 V regulation across -65°C to +175°C ambient range and exhibits minimal capacitance per Figure 2. Its 250 °C/W junction-to-lead thermal resistance requires 3/8" (10 mm) lead length from body for full 500 mW rating.
The device uses hermetically sealed glass construction with tin-lead or RoHS-compliant matte-tin plating, supports MIL-PRF-19500 screening with prefix options, and achieves radiation hardness per MicroNote 050 - making it suitable for harsh-environment analog references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 130 V @ 0.95 mA test current - defines primary regulation point under standard bias |
| Zener Tolerance | ±5% (B suffix) - ensures output stays within 123.5–136.5 V at IZT |
| Power Dissipation | 500 mW at 25°C, derated linearly above 50°C lead temp - sets max continuous power handling |
| Zener Impedance | 4500 Ω max @ 0.25 mA - indicates dynamic resistance affecting regulation stability under light load |
| Temp Coefficient | +0.110 %/°C - quantifies voltage drift magnitude over temperature for reference accuracy planning |
| Reverse Current | 0.1 μA max @ 104 V - defines leakage level below regulation knee, critical for low-power standby |
| Forward Voltage | 1.5 V max @ 200 mA - specifies forward conduction drop if accidentally forward-biased |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5274B-TP | Same 130 V, ±5%, DO-35 package but with "TP" tape-and-reel designation instead of "TR"; identical electrical specs | No functional difference; "TP" is Diodes Inc. branding variant, same JEDEC registration | Select 1N5274B-TP only when sourcing from Diodes Inc. distribution channels |
| MMBZ5274B-7-F | SOT-23 surface-mount package, same 130 V/±5% rating but 225 mW power rating and 3000 Ω ZzK max | Requires PCB layout change; unsuitable for high-temp axial-lead mounting or >225 mW loads | Choose MMBZ5274B-7-F only for space-constrained consumer designs where 225 mW suffices |
Compared with 1N5274BE3/TR, 1N5274B-TP offers identical performance in alternate packaging logistics, while MMBZ5274B-7-F trades axial-lead ruggedness and 500 mW capability for SMT compatibility - making the original optimal for high-reliability, high-power, through-hole applications.

FAQ
What is the Zener voltage tolerance of the 1N5274BE3/TR?
The 1N5274BE3/TR has a nominal Zener voltage of 130 V with a ±5% tolerance, indicated by the "B" suffix per JEDEC standard. This means the actual regulation voltage falls between 123.5 V and 136.5 V when measured at the specified 0.95 mA test current and 25°C ambient temperature. The tolerance is guaranteed across the full operating temperature range.
Does the 1N5274BE3/TR require heatsinking for 500 mW operation?
No external heatsink is required for the 1N5274BE3/TR at 500 mW, provided the lead temperature at 3/8" (10 mm) from the glass body remains ≤50°C. Its 250 °C/W junction-to-lead thermal resistance allows full power dissipation with proper lead length - but derating applies above 50°C lead temperature per Figure 1 in the datasheet.
Is the 1N5274BE3/TR RoHS compliant?
Yes, the 1N5274BE3/TR is RoHS compliant, confirmed by the "e3" suffix in its part number. It features annealed matte-tin plating per MIL-STD-750 Method 2026 and meets EU Directive 2011/65/EU requirements. Lead-free assembly is supported with standard 260°C/10s solder profiles.
What is the maximum reverse leakage current for the 1N5274BE3/TR?
The 1N5274BE3/TR has a maximum reverse leakage current (IR) of 0.1 μA when tested at 104 V (80% of nominal 130 V Zener voltage). This ultra-low leakage supports high-impedance reference nodes and minimizes power loss in battery-backed or low-quiescent-current systems.
Can the 1N5274BE3/TR be used in radiation-intensive environments?
Yes, the 1N5274BE3/TR is inherently radiation hard per MicroNote 050 and has been qualified for use in space and nuclear applications. Its hermetically sealed DO-35 glass package and silicon die design provide proven tolerance to total ionizing dose (TID) without parameter shift or functional failure.
