Product details
Overview
1N5362AE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 28 V, ±10% tolerance (A suffix), 50 mA test current, 6 Ω dynamic impedance at 50 mA, and maximum reverse current of 0.5 μA at 20.1 V. It operates from –65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the 1N5362AE3/TR13 datasheet, 1N5362AE3/TR13 pinout, 1N5362AE3/TR13 application, or 1N5362AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (130 A), voltage regulation (ΔVZ = 3.9 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, with Zener voltage specified at 28 V ±10% under 50 mA DC test current. Its low dynamic impedance (6 Ω) ensures stable regulation across load variations, and its 25 °C/W thermal resistance enables reliable 5 W dissipation when leads are mounted at 3/8″ (10 mm) from body.
The 1N5362AE3/TR13 features cathode band polarity marking, UL94V-0 void-free epoxy encapsulation, and moisture sensitivity level 1 - eliminating dry-pack requirements. It withstands 8.3 ms half-sine surge currents up to 130 A and exhibits <0.5 μA leakage at VR = 20.1 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 28 V ±10% - defines regulated output voltage under 50 mA test current; high-end tolerance limit is 30.8 V for IZM calculation. |
| Power Dissipation | 5.0 W at TL = 25 °C - requires ≥10 mm lead length from body for full rating; derates linearly above 25 °C. |
| Dynamic Impedance (ZZ) | 6 Ω at IZT = 50 mA - determines output voltage variation under changing load current; lower value improves regulation stability. |
| Maximum Reverse Current | 0.5 μA at VR = 20.1 V - ensures minimal leakage in standby mode; critical for low-power bias networks. |
| Surge Current (IZSM) | 130 A (8.3 ms half-sine) - supports transient overvoltage clamping without failure in unprotected input stages. |
| Voltage Regulation (ΔVZ) | 3.9 V - difference between VZ measured at 10% and 50% of IZM; quantifies regulation linearity across operating range. |
| Thermal Resistance | 25 °C/W junction-to-lead - enables thermal design with discrete heatsinking via PCB copper or chassis mounting. |
Pinout & Package
Package: Axial-leaded T-18 plastic case (JEDEC DO-204AL), void-free UL94V-0 epoxy body, matte-tin plated leads, cathode indicated by black band. Weight: 0.7 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Non-banded lead | Connected to circuit ground or lower-potential node; forward voltage ≤1.2 V @ 1.0 A. |
| Cathode | Banded lead | Connected to regulated voltage node; must be held positive relative to anode to maintain Zener conduction. |
Key Features
| Feature | Design Value |
|---|---|
| RoHS Compliant Plating | Matte-tin annealed leads meeting MIL-STD-750 Method 2026 - ensures solderability without lead-based alloys. |
| ESD Robustness | Nonsensitive per MIL-STD-750 Method 1020 - eliminates need for handling precautions in assembly environments. |
| Moisture Sensitivity | Level 1 per IPC/JEDEC J-STD-020B - no dry pack or baking required prior to reflow or wave soldering. |
| Surge Withstand | 130 A peak non-recurrent 8.3 ms half-sine - provides single-event overvoltage immunity without external TVS. |
| Stable Regulation Range | Operates from –65 °C to +150 °C - suitable for automotive engine control and industrial power supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5362B | Same 28 V nominal voltage but ±5% tolerance (B suffix); 50 mA IZT, 6 Ω ZZ, identical package and thermal specs. | Higher voltage accuracy required where ±5% is mandated by system spec (e.g., MIL-PRF-19500 screened designs). | Select 1N5362B when tighter regulation tolerance is needed; same footprint and thermal behavior. |
| MMSZ5262ET1G | Surface-mount SOD-123 package; 28 V ±5%, 20 mA IZT, 35 Ω ZZ, 500 mW power rating - not a drop-in replacement. | Used in space-constrained PCBs where axial leads are impractical; unsuitable for 5 W continuous dissipation. | Choose MMSZ5262ET1G only for low-power, high-density layouts; requires layout redesign and derated current handling. |
Compared with 1N5362B and MMSZ5262ET1G, the 1N5362AE3/TR13 offers the highest continuous power capability (5 W) in axial form factor, while trading voltage tolerance for cost and availability - making it optimal for commercial-grade power supplies where ±10% is acceptable and through-hole assembly is preferred.

FAQ
What is the Zener voltage tolerance of the 1N5362AE3/TR13?
The 1N5362AE3/TR13 has a Zener voltage tolerance of ±10%, denoted by the "A" suffix in the part number. Its nominal regulation voltage is 28 V, meaning the actual measured VZ falls between 25.2 V and 30.8 V at 50 mA test current and 25 °C lead temperature. This tolerance is confirmed in the manufacturer's electrical characteristics table and applies across the full operating temperature range.
Can the 1N5362AE3/TR13 be used in surface-mount designs?
No - the 1N5362AE3/TR13 uses an axial-leaded T-18 (DO-204AL) package and is not compatible with surface-mount assembly processes. For SMT equivalents, Microsemi offers the SMBJ5362B or SMBG5362B in SMB/SMBG packages; however, those parts differ in thermal performance, surge rating, and mounting method, and are not direct replacements for the 1N5362AE3/TR13.
What is the maximum steady-state power dissipation for the 1N5362AE3/TR13 on a standard PCB?
When mounted on a FR4 PCB with 1 oz copper, 4 mm² pads, and 1 mm × 25 mm traces, the 1N5362AE3/TR13 delivers 1.47 W steady-state power at 25 °C ambient - derived from its 85 °C/W junction-to-ambient thermal resistance. Full 5 W operation requires lead temperature control at 25 °C, achieved via ≥10 mm lead length from body and/or external heatsinking.
Does the 1N5362AE3/TR13 require dry packing before reflow soldering?
No - the 1N5362AE3/TR13 has moisture sensitivity level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored and processed without dry pack or baking. Its void-free epoxy encapsulation and Level 1 classification eliminate moisture-related popcorning risk during standard reflow or wave soldering profiles, including peak temperatures up to 260 °C for 10 seconds.
How is polarity identified on the 1N5362AE3/TR13?
The 1N5362AE3/TR13 uses a cathode band marking: the end with the black band is the cathode terminal and must be held at a higher potential than the unmarked (anode) end to achieve Zener conduction. This polarity is consistent across all 1N53xx devices and is documented in the mechanical drawings and packaging section of the Microsemi datasheet.
