Product details
Overview
1N5365BE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 36 V, ±5% tolerance (B suffix), maximum dynamic impedance of 11 Ω at 30 mA test current, and maximum reverse current of 0.5 μA at 27.4 V. It operates from –65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in industrial power supplies.
For engineers reviewing the 1N5365BE3/TR13 datasheet, 1N5365BE3/TR13 pinout, 1N5365BE3/TR13 application, or 1N5365BE3/TR13 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (160 A), voltage regulation (ΔVZ = 3.3 V), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device functions as a two-terminal voltage regulator operating in reverse breakdown mode, with specified Zener voltage measured at 30 mA (IZT) and thermal derating defined for lead temperature (TL) and ambient (TA) mounting conditions. Its low dynamic impedance (11 Ω) and tight voltage regulation (ΔVZ = 3.3 V) ensure stable reference performance across load and temperature variations.
The 1N5365BE3/TR13 uses a void-free thermosetting epoxy T-18 package with cathode band polarity marking, rated for 5 W steady-state dissipation at TL < 25 °C with 3/8″ lead length, and supports surge currents up to 160 A (8.3 ms half-sine). It meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry pack requirement.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±5% - precise regulation point for 33–39 V system references |
| Test Current (IZT) | 30 mA - standard bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 11 Ω max - low AC resistance ensures minimal output voltage variation under load transients |
| Max Reverse Current (IR) | 0.5 μA at 27.4 V - ultra-low leakage preserves regulation integrity in high-impedance bias networks |
| Power Dissipation (PD) | 5.0 W at TL < 25 °C - requires minimum 3/8″ lead length heat sinking for full-rated operation |
| Thermal Resistance (RθJL) | 25 °C/W junction-to-lead - enables predictable thermal design when mounted with adequate copper heatsinking |
| Surge Current (IZSM) | 160 A (8.3 ms half-sine) - withstands transient overvoltage events without degradation |
Pinout & Package
T-18 axial-leaded plastic package with cathode indicated by color band; leads are annealed matte-tin plated per MIL-STD-750, solderable at 260 °C for 10 s max; weight 0.7 g; moisture sensitivity Level 1 (no dry pack required).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-voltage side in regulation | Connected to circuit ground or lower-potential node during Zener operation |
| Cathode | Reverse-biased regulation terminal / high-voltage side | Banded end; connected to unregulated input rail; establishes regulated output at cathode potential |
Key Features
| Feature | Design Value |
|---|---|

| JEDEC-registered 1N53xxB series | Industry-standard footprint and electrical behavior ensures supply chain interoperability and legacy design compatibility |
| Low voltage regulation (ΔVZ) | 3.3 V difference between 10% and 50% of IZM - enables stable reference in varying current conditions |
| Nonsensitive to ESD | Qualified per MIL-STD-750 Method 1020 - no special handling required during assembly or field service |
| High surge current capability | 160 A peak (8.3 ms half-sine) - protects downstream circuitry from lightning-induced or inductive-switching transients |
Applications
| Industrial Power Supply Reference | Overvoltage Clamp for DC Bus |
|---|---|
Use Scenario: Stable 36 V reference in isolated flyback feedback loop of 48 V telecom power supply. IC Role / Device Role / Timing Role: Zener diode provides precise voltage threshold for optocoupler biasing and error amplifier reference.

Use Value: Low ΔVZ (3.3 V) and tight 5 W power rating enable repeatable 36 V reference under varying load conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B (non-e3, non-TR) | Same electrical specs but SnPb plating and bulk packaging; not RoHS-compliant | Limited to legacy military/aerospace programs requiring tin-lead finish | Select only if SnPb finish and tape-and-reel are not required |
| SMBJ5365B | Surface-mount SMB package; same 36 V/5 W rating; 120 A surge rating vs. 160 A | Used where board space is constrained and automated SMT assembly is preferred | Choose for high-density PCBs; verify thermal pad layout matches FR4 derating curve |
Compared with 1N5365BE3/TR13, the 1N5365B lacks RoHS compliance and tape-and-reel packaging, while SMBJ5365B trades higher surge robustness and axial-mount flexibility for compact SMT integration-making the 1N5365BE3/TR13 optimal for through-hole industrial power and protection designs requiring full environmental compliance and proven surge resilience.

FAQ
What is the Zener voltage tolerance of the 1N5365BE3/TR13?
The 1N5365BE3/TR13 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its nominal 36 V regulation point falls within 34.2 V to 37.8 V at 30 mA test current and 25 °C lead temperature. The tolerance remains valid across the full operating temperature range of –65 °C to +150 °C, as confirmed in Microsemi's REV D datasheet.
Does the 1N5365BE3/TR13 require dry packing before reflow soldering?
No, the 1N5365BE3/TR13 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity Level 1 classification, meaning it can be stored indefinitely at ambient conditions without baking. Its void-free thermosetting epoxy T-18 package inherently resists moisture absorption, eliminating pre-reflow bake cycles.
What is the maximum continuous power dissipation for the 1N5365BE3/TR13 on a standard FR4 PCB?
When mounted on a standard FR4 PCB (1 oz Cu) with 4 mm² copper pads and 1 mm track width, the 1N5365BE3/TR13 is rated for 1.47 W steady-state power dissipation at 25 °C ambient temperature. This derated value reflects its 85 °C/W junction-to-ambient thermal resistance under those specific board-layout conditions.
How is polarity marked on the 1N5365BE3/TR13?
The 1N5365BE3/TR13 uses a cathode band marking: a single colored band near one end of the cylindrical body identifies the cathode terminal. During Zener operation, this banded end must be held at a higher potential than the anode (unbanded end) to achieve reverse-bias regulation. Forward voltage is guaranteed ≤1.2 V at 1.0 A.
What does the "TR13" suffix indicate in 1N5365BE3/TR13?
The "TR13" suffix indicates tape-and-reel packaging per EIA-296 standard, with 13-inch reels. This format supports automated pick-and-place assembly and ensures consistent orientation (cathode band facing outward) for high-volume manufacturing. The "e3" denotes RoHS-compliant matte-tin plating, and "B" specifies ±5% Zener voltage tolerance.
