Product details
Overview
1N5364E3/TR13 from Microsemi is a 33 V, ±5% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply feedback loops, overvoltage protection circuits, and precision reference applications. It delivers 33 V regulation at 40 mA test current, with 10 Ω dynamic impedance, 150 mA maximum Zener current, and operates across –65°C to +150°C.
For engineers reviewing the 1N5364E3/TR13 datasheet, 1N5364E3/TR13 pinout, 1N5364E3/TR13 application, or 1N5364E3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (150 A), voltage regulation (ΔVZ = 3.5 V), and RoHS-compliant matte-tin plating.
Technical Context
This device functions as a two-terminal voltage reference by operating in reverse breakdown, maintaining stable output voltage across wide current (1–150 mA) and temperature (–65°C to +150°C) ranges. Its low 25 °C/W junction-to-lead thermal resistance enables reliable 5 W dissipation with minimal heatsinking when leads are trimmed to 10 mm.
The 1N5364E3/TR13 exhibits 10 Ω dynamic impedance at 40 mA and 3.5 V voltage regulation (ΔVZ) between 10% and 50% of IZM - critical for minimizing output drift in regulated DC-DC converters and analog sensor biasing circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 33 V ±5% at 40 mA - defines nominal regulation point with tight tolerance for stable reference generation |
| Power Dissipation | 5.0 W at 25°C lead temperature - supports high-current regulation without forced cooling when mounted per JEDEC T-18 spec |
| Dynamic Impedance (ZZ) | 10 Ω at IZT = 40 mA - ensures minimal output voltage variation under load transients |
| Max Reverse Current (IR) | 0.5 μA at 25.1 V - guarantees low leakage in high-impedance reference paths |
| Voltage Regulation (ΔVZ) | 3.5 V - measured between 10% and 50% of IZM, indicating stability across operating current range |
| Surge Current (IZSM) | 150 A (8.3 ms half-sine) - provides robust transient overvoltage clamping capability |
| Thermal Resistance | 25 °C/W junction-to-lead (3/8″ lead length) - enables predictable thermal design in through-hole PCB layouts |
Pinout & Package
Package: Axial-leaded T-18 plastic encapsulated case per JEDEC DO-204AL. Cathode indicated by color band; operated with banded end positive relative to unbanded end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reverse-biased reference terminal | Connected to circuit ground or lower-potential node; carries full Zener current during regulation |
| Cathode | Regulated output terminal | Marked with band; supplies stable 33 V reference to feedback networks or protection comparators |
Key Features
| Feature | Design Value |
|---|---|
| RoHS-compliant matte-tin plating | Enables lead-free reflow soldering per MIL-STD-750 Method 2026 without tin whisker risk |
| Moisture sensitivity Level 1 | Eliminates dry-pack requirement and floor-life constraints for production handling |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces need for ESD controls during manual assembly and board-level testing |
| High surge current rating (150 A) | Provides single-event overvoltage protection without external TVS devices in many industrial inputs |
| Stable regulation over –65°C to +150°C | Supports operation in automotive engine compartments and outdoor telecom enclosures |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5364B | Same 33 V ±5%, but non-RoHS tin-lead plating; no e3 suffix | Not suitable for lead-free manufacturing; identical electrical specs and thermal performance | Select 1N5364B only if legacy Pb-based assembly is required and RoHS compliance is waived |
| MMSZ5255ET1G | Surface-mount SOD-123 package; 33 V ±5%; 500 mW rating; 30 Ω ZZ | Limited to low-power applications; cannot replace 1N5364E3/TR13 in 5 W designs without parallel devices | Choose MMSZ5255ET1G only for space-constrained PCBs where power dissipation ≤0.5 W is sufficient |
Compared with 1N5364B and MMSZ5255ET1G, the 1N5364E3/TR13 uniquely combines RoHS compliance, 5 W power handling, axial-leaded mechanical robustness, and 10 Ω dynamic impedance - making it the sole option for high-reliability through-hole 33 V regulation in industrial power systems.

FAQ
What is the Zener voltage tolerance of the 1N5364E3/TR13?
The 1N5364E3/TR13 has a Zener voltage tolerance of ±5%, as indicated by the "B" suffix in its full designation. This means its nominal 33 V regulation point falls within 31.35 V to 34.65 V at 40 mA test current and 25°C lead temperature. The e3 suffix confirms RoHS compliance but does not affect voltage tolerance.
Can the 1N5364E3/TR13 be used in surface-mount designs?
No - the 1N5364E3/TR13 uses an axial-leaded T-18 package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5364B (DO-214AA) and SMBG5364B (DO-214AB), both rated for 5 W and sharing identical electrical specs including 33 V ±5% and 10 Ω dynamic impedance.
What is the maximum steady-state power dissipation for the 1N5364E3/TR13 on a standard FR4 PCB?
When mounted on a standard FR4 PCB (1 oz copper, 4 mm² pads, 1 mm track width, 25 mm length), the 1N5364E3/TR13 has a steady-state power rating of 1.47 W at 25°C ambient. This derates linearly above 25°C per the 85°C/W junction-to-ambient thermal resistance specified in the datasheet.
Does the 1N5364E3/TR13 require dry-pack moisture protection before PCB assembly?
No - the 1N5364E3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity Level 1, meaning it can be stored indefinitely at ambient conditions without dry-pack desiccant or floor-life tracking. This eliminates baking requirements and simplifies manufacturing logistics for high-volume production.
How is polarity marked on the 1N5364E3/TR13?
The cathode of the 1N5364E3/TR13 is marked by a distinct color band on the body. During operation, the banded end must be held at a higher potential than the unbanded (anode) end to achieve reverse-bias Zener conduction. Incorrect polarity results in forward conduction (~1.2 V drop) and loss of regulation.
