Product details
Overview
1N5361BE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with a nominal regulation voltage of 27 V, ±5% tolerance (B suffix), 50 mA test current (IZT), 5.0 Ω dynamic impedance (ZZ), and 120 mA maximum Zener current (IZM) when adequately heat-sunk. It operates across –65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in industrial power supplies.
For engineers reviewing the 1N5361BE3/TR13 datasheet, 1N5361BE3/TR13 pinout, 1N5361BE3/TR13 application, or 1N5361BE3/TR13 equivalent, key selection criteria include Zener voltage stability under varying load currents, low dynamic impedance at 50 mA, thermal resistance (25 °C/W junction-to-lead), RoHS compliance (e3 suffix), and tape-and-reel packaging (TR13).
Technical Context
This device functions as a two-terminal voltage regulator, maintaining stable reverse-biased conduction above its 27 V breakdown threshold. Its 5.0 Ω dynamic impedance ensures minimal voltage variation across 10–50% of IZM, and its 25 °C/W junction-to-lead thermal resistance enables reliable 5 W operation with 3/8″ lead length heat sinking.
The 1N5361BE3/TR13 exhibits 0.60 V maximum voltage regulation (ΔVZ) between 10% and 50% of IZM, and supports surge currents up to 120 A (8.3 ms half-sine). Its cathode band marking and tin-plated leads comply with MIL-STD-750 solderability requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±5% - precise regulation point for 24 V system clamping and reference generation |
| Test Current (IZT) | 50 mA - standardized operating point for measuring VZ and ZZ |
| Dynamic Impedance (ZZ) | 5.0 Ω - low AC resistance ensures <0.25 V deviation over 5–25 mA current change |
| Max Zener Current (IZM) | 120 mA - maximum continuous DC current at TL = 25 °C with 3/8″ lead heat sink |
| Power Dissipation | 5.0 W at TL = 25 °C - full-rated power achievable only with proper lead-length thermal path |
| Thermal Resistance | 25 °C/W junction-to-lead - enables direct thermal modeling for PCB layout and heatsink design |
| Reverse Leakage (IR) | 0.5 μA @ 20.1 V - negligible standby current below regulation threshold |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5361BRLG | Same 27 V ±5%, 5 W rating, but in bulk packaging (no TR13); identical electrical specs and T-18 package | No tape-and-reel - unsuitable for automated assembly; requires manual or vibratory feeding | Select 1N5361BRLG only for prototyping or low-volume hand-soldered builds |
| MMSZ5260ET1G | 27 V ±5%, but 500 mW SOD-123 surface-mount package; 10x lower power; 30 Ω ZZ; 20 mA IZM | Cannot replace 1N5361BE3/TR13 in 5 W applications; limited to low-power bias/reference roles | Choose MMSZ5260ET1G only where board space constraints prohibit axial leads and power <0.5 W suffices |
Compared with 1N5361BRLG and MMSZ5260ET1G, the 1N5361BE3/TR13 uniquely delivers 5 W regulation in tape-and-reel format with industry-standard axial mounting - essential for high-reliability industrial power designs requiring automated assembly and robust transient handling.

FAQ
What is the Zener voltage tolerance of the 1N5361BE3/TR13?
The 1N5361BE3/TR13 has a ±5% Zener voltage tolerance, confirmed by the "B" suffix per Microsemi's documentation. This means its measured VZ at 50 mA falls within 25.65 V to 28.35 V at 25 °C. The e3 suffix indicates RoHS compliance but does not affect voltage tolerance. This tolerance is tighter than the ±10% (A suffix) or ±20% (no suffix) variants in the same family.
Can the 1N5361BE3/TR13 be used without a heatsink?
The 1N5361BE3/TR13 can dissipate up to 1.47 W at 25 °C ambient when mounted on FR4 with specified copper pads - but its full 5 W rating requires a 3/8″ (10 mm) lead length acting as a thermal path to ambient. Without adequate lead-length heat sinking, continuous operation above ~1.5 W risks exceeding the 150 °C max junction temperature. Derating curves in the datasheet must be followed for safe operation.
What does the "TR13" suffix mean in 1N5361BE3/TR13?
The "TR13" suffix denotes tape-and-reel packaging per EIA-296 standard, with 1,300 units per reel. This format enables compatibility with automated pick-and-place equipment configured for axial-leaded components. The base part 1N5361BE3 remains electrically and mechanically identical; TR13 adds only packaging configuration - no parameter or reliability changes.
How does the 1N5361BE3/TR13 handle surge currents?
The 1N5361BE3/TR13 is rated for 120 A peak non-recurrent surge current (IZSM) in an 8.3 ms half-sine waveform, verified per Microsemi's test conditions. This capability allows it to absorb common industrial transients such as inductive switch-off spikes or ESD events without degradation, provided the average power remains within 5 W limits and thermal mass prevents cumulative heating.
Is the 1N5361BE3/TR13 suitable for precision reference applications?
The 1N5361BE3/TR13 provides moderate precision: ±5% initial tolerance, 0.60 V voltage regulation (ΔVZ) across 10–50% of IZM, and low 5.0 Ω dynamic impedance. It is appropriate for non-critical references in power supplies and protection circuits but lacks the temperature coefficient and long-term stability of temperature-compensated or buried-Zener references like the LM399 or LTZ1000.
