Product details
Overview
1N5353AE3/TR13 from Microsemi is a 5 W axial-leaded Zener diode with nominal regulation voltage of 16 V, ±10% tolerance (A suffix), 75 mA maximum Zener test current (IZT), 2.5 Ω maximum dynamic impedance (ZZ), and 1.0 μA maximum reverse leakage at 11.5 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 1N5353AE3/TR13 datasheet, 1N5353AE3/TR13 pinout, 1N5353AE3/TR13 application, or 1N5353AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (6.0 A), voltage regulation (ΔVZ = 0.30 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. Its 16 V nominal Zener voltage is specified at 75 mA IZT with ±10% tolerance, and it maintains stable regulation across 10–50% of IZM (6.0 A) with ΔVZ ≤ 0.30 V.
Thermal design relies on lead-length-dependent junction-to-lead resistance (25 °C/W at 3/8″ lead length); when mounted on FR4 with 4 mm² copper pads, junction-to-ambient rises to 85 °C/W. The cathode band indicates polarity, and operation requires the banded end to be positive relative to the anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 16 V ±10% - defines regulated output voltage under 75 mA test current; high-end limit is 17.6 V for IZM calculation. |
| Power Dissipation | 5.0 W at TL = 25 °C - requires minimum 3/8″ lead length from body for full rating; derates linearly above 25 °C. |
| Dynamic Impedance (ZZ) | 2.5 Ω max - low AC impedance ensures minimal voltage shift under varying load currents near IZT. |
| Reverse Leakage (IR) | 1.0 μA max at VR = 11.5 V - confirms tight blocking behavior below knee voltage, critical for low-power standby circuits. |
| Surge Current (IZSM) | 6.0 A peak (8.3 ms half-sine) - supports transient overvoltage clamping without failure in surge-prone inputs. |
| Voltage Regulation (ΔVZ) | 0.30 V max - difference between VZ measured at 10% and 50% of IZM; quantifies regulation linearity over operating range. |
| Thermal Resistance | 25 °C/W junction-to-lead - enables thermal modeling for PCB layout; 85 °C/W junction-to-ambient on FR4 with defined copper area. |
Pinout & Package
Package: Axial-leaded T-18 molded epoxy case (UL94V-0), 0.7 g weight, cathode indicated by colored band. Leads are annealed matte-tin plated (RoHS compliant, e3 suffix), solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node in shunt regulator configuration | Connected to system ground or lower-potential rail; carries full load current when regulating. |
| Cathode | Regulated output node | Banded end; held at stable 16 V relative to anode; must be biased positive w.r.t. anode to enter breakdown. |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener | Complies with industry-standard 1N53xxB series mechanical and electrical definitions for interchangeability. |
| Moisture Sensitivity Level 1 | No dry pack required before SMT reflow; compatible with standard assembly processes without baking. |
| Nonsensitive to ESD | Qualified per MIL-STD-750 Method 1020 - eliminates need for special ESD handling in production. |
| High Surge Withstand | Rated for 6.0 A non-repetitive surge (8.3 ms) - protects downstream circuitry during lightning or inductive switching events. |
| RoHS Compliant Plating | e3 suffix denotes matte-tin lead finish meeting EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 1. |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Reference |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5353B | Same 16 V nominal VZ, but ±5% tolerance (B suffix) vs. ±10% (A suffix); identical package, thermal, and surge specs. | Higher voltage accuracy required in precision feedback loops where 0.8 V tighter tolerance improves output regulation. | Select 1N5353B when tighter VZ tolerance is needed; otherwise 1N5353AE3/TR13 offers cost-effective performance for general-purpose clamping. |
| MMSZ5245B-TP | Surface-mount SOD-123 package, 500 mW rating, 16 V ±5%, 100 mA IZT - not drop-in; lower power and different mounting. | Suitable only for low-power, space-constrained designs; cannot replace 5 W dissipation requirement without parallel devices or heatsinking. | Choose MMSZ5245B-TP only for PCB area-limited consumer applications; avoid in industrial power supplies requiring 5 W continuous dissipation. |
Compared with 1N5353B and MMSZ5245B-TP, the 1N5353AE3/TR13 uniquely balances axial-leaded serviceability, 5 W thermal capability, and RoHS-compliant plating-making it optimal for repairable, high-reliability power systems where lead-forming and manual replacement are routine.

FAQ
What is the Zener voltage tolerance for 1N5353AE3/TR13?
The 1N5353AE3/TR13 has a ±10% Zener voltage tolerance, as indicated by the "A" suffix per Microsemi's documentation. This means its actual regulation voltage falls between 14.4 V and 17.6 V at 75 mA test current and 25 °C lead temperature. The e3/TR13 designation confirms RoHS-compliant plating and tape-and-reel packaging.
Can 1N5353AE3/TR13 be used in surface-mount designs?
No-1N5353AE3/TR13 is an axial-leaded T-18 package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5353A series; however, those parts differ in thermal performance, surge rating, and footprint. Direct substitution would require PCB redesign and thermal validation.
What is the maximum steady-state power dissipation for 1N5353AE3/TR13 on a standard FR4 board?
When mounted on FR4 with 1 oz copper, 4 mm² pads, and 1 mm × 25 mm traces, the 1N5353AE3/TR13 delivers 1.47 W steady-state power at TA = 25 °C. This derates linearly above 25 °C per the 85 °C/W junction-to-ambient thermal resistance specified in the datasheet.
Does 1N5353AE3/TR13 require dry packing before reflow soldering?
No-1N5353AE3/TR13 has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it may be stored and processed without dry packing or baking. Its void-free epoxy encapsulation prevents moisture ingress, eliminating preconditioning steps in standard assembly lines.
How is polarity identified on 1N5353AE3/TR13?
Polarity is marked by a cathode band on the body of the 1N5353AE3/TR13. During operation, the banded (cathode) end must be held positive relative to the unmarked (anode) end to achieve Zener breakdown regulation. Reversing polarity subjects the device to forward conduction with VF ≤ 1.2 V at 1.0 A, not regulation.
