Product details
Overview
1N5365AE3/TR13 from Microsemi is a 5 W axial-leaded Zener diode with nominal regulation voltage of 36 V, ±10% tolerance (A suffix), 30 mA test current (IZT), 11 Ω dynamic impedance (ZZ), and maximum reverse current of 0.5 μA at 28.1 V (VR). 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 1N5365AE3/TR13 datasheet, 1N5365AE3/TR13 pinout, 1N5365AE3/TR13 application, or 1N5365AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, 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 in reverse-biased mode, maintaining stable output across wide current (30 mA IZT to 160 mA IZM) and temperature ranges. Its low dynamic impedance (11 Ω) and tight ΔVZ (3.3 V) ensure minimal voltage drift under load variation.
The 1N5365AE3/TR13 uses void-free thermosetting epoxy encapsulation (UL94V-0), cathode-band polarity marking, and is rated for 260 °C soldering (10 s). Its 25 °C/W junction-to-lead thermal resistance enables high-current operation when mounted with ≥10 mm lead length from body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 36 V ±10% - defines nominal regulation point; high-end tolerance limit is 39.6 V for IZM calculation. |
| Test Current (IZT) | 30 mA - operating point where VZ and ZZ are specified; ensures stable regulation under typical bias conditions. |
| Dynamic Impedance (ZZ) | 11 Ω - low AC resistance minimizes output voltage variation during transient current changes. |
| Max Reverse Current (IR) | 0.5 μA @ 28.1 V - confirms sharp knee and low leakage below regulation threshold. |
| Max Regulator Current (IZM) | 160 mA - maximum DC current at TL = 25 °C with adequate heat sinking; supports robust overvoltage clamping. |
| Surge Current (IZSM) | 160 A - peak non-repetitive half-sine (8.3 ms) rating for transient suppression in power rails. |
| Voltage Regulation (ΔVZ) | 3.3 V - difference between VZ measured at 10% and 50% of IZM; quantifies regulation linearity. |
Pinout & Package
Package: Axial-leaded T-18 plastic case (void-free UL94V-0 epoxy), cathode indicated by band; leads plated with RoHS-compliant matte tin per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Reference ground node | Connected to circuit ground or lower-potential rail; forms reference return path in shunt regulator topology. |
| Cathode | Zener regulation terminal / Output node | Banded end; connected to regulated voltage node; sinks current to maintain fixed VZ across load. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5365B | Same 36 V, ±5% tolerance (B suffix); tighter voltage spec but higher cost and no RoHS compliance. | Suitable where tighter regulation (±5%) is required and lead-free assembly is not mandated. | Select 1N5365B if system-level qualification requires ±5% VZ stability and legacy Pb-based solder processes are used. |
| MMBZ5245B (SOT-23) | Surface-mount, 33 V, ±5%, 0.5 W - lower power, smaller footprint, different thermal profile. | Used in space-constrained PCBs where axial leads are impractical; not interchangeable without layout change. | Choose MMBZ5245B only for new SMT designs needing compact size; not a drop-in replacement for 1N5365AE3/TR13. |
Compared with 1N5365B and MMBZ5245B, the 1N5365AE3/TR13 uniquely combines RoHS compliance, 5 W power handling, axial mounting flexibility, and ±10% tolerance-making it optimal for cost-sensitive, through-hole industrial power regulation where lead-free assembly and surge resilience are mandatory.

FAQ
What is the Zener voltage tolerance for 1N5365AE3/TR13?
The "A" suffix in 1N5365AE3/TR13 specifies a ±10% Zener voltage tolerance. This means the measured VZ at 30 mA (IZT) falls between 32.4 V and 39.6 V at 25 °C. The tolerance is confirmed in the manufacturer's Electrical Characteristics table and applies across the full operating temperature range of –65 °C to +150 °C. This tolerance level balances cost and performance for general-purpose industrial regulation where tight voltage control is not critical.
Does 1N5365AE3/TR13 require dry packing before PCB assembly?
No, the 1N5365AE3/TR13 has Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it does not require dry packing or baking prior to reflow soldering. Its void-free thermosetting epoxy encapsulation prevents moisture ingress, eliminating handling delays and reducing manufacturing risk. This specification is explicitly stated in the Features section of the official Microsemi datasheet for the 1N5333B–1N5388B series.
What is the maximum steady-state power dissipation for 1N5365AE3/TR13 at ambient temperature?
When mounted on an FR4 PCB with 1 oz copper, 4 mm² pads, and 1 mm × 25 mm traces, the 1N5365AE3/TR13 delivers 1.47 W steady-state power at TA = 25 °C. This derated value reflects its 85 °C/W junction-to-ambient thermal resistance under those specific board conditions. At lead temperature TL = 25 °C (3/8″ from body), it sustains the full 5.0 W rating-confirming its suitability for chassis-mounted or heatsinked high-power applications.
How is polarity marked on the 1N5365AE3/TR13 package?
The cathode of the 1N5365AE3/TR13 is marked by a distinct color band on the axial plastic body. During operation, the banded end must be held at a more positive potential than the anode to achieve Zener breakdown and regulation. This polarity marking is standardized across the 1N53xx series and is verified in the Mechanical and Packaging section of the Microsemi datasheet, which also specifies that the diode must be operated in reverse-biased configuration for voltage regulation.
What surge current rating does 1N5365AE3/TR13 support?
The 1N5365AE3/TR13 supports a maximum non-repetitive surge current (IZSM) of 160 A, defined as the peak amplitude of an 8.3 ms half-sine waveform. This rating is validated per Note 5 in the datasheet and enables reliable transient suppression in applications such as automotive load-dump events or industrial motor drive switching noise. The surge capability is directly enabled by its 5 W power rating and low thermal resistance design.
