Product details
Overview
1N5356AE3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 19 V, ±10% tolerance (A suffix), 65 mA test current (IZT), 3.0 Ω maximum dynamic impedance (ZZ), and 75 mA maximum Zener current (IZM). 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 1N5356AE3/TR13 datasheet, 1N5356AE3/TR13 pinout, 1N5356AE3/TR13 application, or 1N5356AE3/TR13 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (120 A), 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, with cathode indicated by a band and required to be held positive relative to the anode. Its regulation stability relies on low dynamic impedance (3.0 Ω) at 65 mA and minimal voltage variation (ΔVZ = 0.40 V) between 10% and 50% of IZM.
The 1N5356AE3/TR13 uses void-free UL94V-0 thermosetting epoxy packaging with 0.7 g mass and T-18 axial outline. Thermal performance is specified for 3/8" (10 mm) lead length from body (25 °C/W) and FR4 board mounting (85 °C/W), enabling reliable operation up to 5 W at TL < 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19 V ±10% - defines stable regulation point under reverse bias at 65 mA test current |
| Power Dissipation | 5.0 W at TL < 25°C - requires minimum 3/8" lead length heat sinking for full rating |
| Dynamic Impedance (ZZ) | 3.0 Ω max @ IZT = 65 mA - ensures low voltage deviation across load current changes |
| Max Reverse Current (IR) | 0.5 μA @ VR = 14.4 V - guarantees high blocking integrity below regulation threshold |
| Surge Current (IZSM) | 120 A peak (8.3 ms half-sine) - supports transient overvoltage clamping without failure |
| Voltage Regulation (ΔVZ) | 0.40 V - measured as difference between VZ at 10% and 50% of IZM (7.5 mA and 37.5 mA) |
| Thermal Resistance | 25 °C/W junction-to-lead - enables direct thermal path to PCB copper or chassis via leads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5356B | ±5% tolerance (B suffix) vs. ±10% (A suffix); otherwise identical VZ, IZT, ZZ, and package | Higher voltage accuracy required in feedback loops where ±10% introduces unacceptable output error | Select 1N5356B when tighter regulation is needed; same thermal and surge ratings apply |
| MMBZ5242B | Surface-mount SOD-123 package; 100 mW rating; 19 V ±5%; not rated for 5 W dissipation | Low-power portable electronics where board space and weight constrain axial-leaded devices | Choose MMBZ5242B only for sub-100 mW applications; cannot replace 1N5356AE3/TR13 in 5 W roles |
Compared with 1N5356B and MMBZ5242B, the 1N5356AE3/TR13 uniquely balances high-power dissipation (5 W), axial-leaded serviceability, and industrial-grade temperature range (–65°C to +150°C), making it suitable for mains-connected power stages where surface-mount alternatives lack thermal capacity.

FAQ
What is the Zener voltage tolerance for 1N5356AE3/TR13?
The 1N5356AE3/TR13 has a Zener voltage tolerance of ±10%, indicated by the "A" suffix in the part number. This means its nominal 19 V regulation point falls within 17.1 V to 20.9 V at 25°C under 65 mA test current. The e3 suffix confirms RoHS compliance, and TR13 denotes tape-and-reel packaging per EIA-296.
How much power can 1N5356AE3/TR13 dissipate continuously?
The 1N5356AE3/TR13 is rated for 5.0 W continuous power dissipation at lead temperature (TL) below 25°C with 3/8" (10 mm) lead length from the body. Derating is required above 25°C - approximately 40 mW/°C - per the published power derating curve. On FR4 board with standard copper pads, steady-state rating drops to 1.47 W at 25°C ambient.
What is the maximum surge current rating for 1N5356AE3/TR13?
The 1N5356AE3/TR13 has a maximum non-repetitive surge current (IZSM) rating of 120 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating enables reliable transient suppression in DC power rails subject to inductive kickback or lightning-induced surges, provided proper PCB layout minimizes parasitic inductance in the clamping path.
Is 1N5356AE3/TR13 suitable for high-temperature environments?
Yes, the 1N5356AE3/TR13 is rated for operation from –65°C to +150°C, with thermal resistance of 25 °C/W junction-to-lead. Its UL94V-0 epoxy package and annealed matte-tin leads maintain mechanical and electrical integrity across this full range, making it appropriate for under-hood automotive modules and industrial motor drive controls.
Does 1N5356AE3/TR13 require dry packing or moisture barrier bags?
No, the 1N5356AE3/TR13 has IPC/JEDEC J-STD-020B Moisture Sensitivity Level 1, meaning it is not moisture-sensitive and does not require dry packing, baking, or humidity-controlled storage. This simplifies handling and eliminates floor-life tracking during assembly, even for lead-free reflow processes.
