Product details
Overview
1N5359E3/TR13 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 24 V, ±5% tolerance (B-suffix equivalent), 3.5 Ω dynamic impedance at 50 mA test current, and maximum reverse current of 0.5 µA at 19.4 V. 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 1N5359E3/TR13 datasheet, 1N5359E3/TR13 pinout, 1N5359E3/TR13 application, or 1N5359E3/TR13 equivalent, key selection criteria include Zener voltage stability under varying load current, low dynamic impedance for tight regulation, thermal resistance (25 °C/W junction-to-lead), RoHS-compliant matte-tin plating, and tape-and-reel packaging for automated assembly.
Technical Context
This device functions as a two-terminal voltage regulator operating in reverse breakdown, maintaining stable output voltage across wide current ranges (50 mA test current, 75 mA max Zener current). Its low 3.5 Ω dynamic impedance ensures minimal voltage shift with load variation, and its 25 °C/W junction-to-lead thermal resistance enables reliable 5 W dissipation with standard lead-length heat sinking.
The 1N5359E3/TR13 features a void-free thermosetting epoxy T-18 package with cathode band marking, RoHS-compliant annealed matte-tin leads per MIL-STD-750 Method 2026, and moisture sensitivity level 1 - eliminating dry-pack requirements. It withstands 8.3 ms half-sine surge currents up to 100 A.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5359B | Same 24 V ±5%, but with SnPb (non-RoHS) plating and bulk packaging (no TR13) | Lacks tape-and-reel automation support and RoHS compliance; unsuitable for new EU-designs | Select 1N5359B only for legacy repair or non-RoHS-constrained environments where reel packaging is unnecessary |
| MMSZ5245B-TP | Surface-mount SOD-123 package, 24 V ±5%, 500 mW rating, 30 Ω ZZ | Lower power (0.5 W vs. 5 W), higher impedance, no axial mounting flexibility | Choose MMSZ5245B-TP only for space-constrained PCBs where full 5 W dissipation is not required |
Compared with 1N5359B and MMSZ5245B-TP, the 1N5359E3/TR13 uniquely combines RoHS compliance, 5 W power handling, axial-leaded mechanical robustness, and tape-and-reel readiness - making it optimal for high-reliability industrial and automotive production lines requiring full regulatory and assembly compatibility.

FAQ
What is the Zener voltage tolerance of the 1N5359E3/TR13?
The 1N5359E3/TR13 has a nominal Zener voltage of 24 V with ±5% tolerance, consistent with the "B" suffix designation in the 1N53xxB family. This tolerance is verified at 25 °C lead temperature with 50 mA test current and applies across the full operating temperature range of –65 °C to +150 °C per Microsemi's published electrical characteristics table.
Does the 1N5359E3/TR13 require dry-pack moisture protection before reflow?
No - the 1N5359E3/TR13 carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it is exempt from dry-pack requirements. Its void-free UL94V-0 epoxy encapsulation and Level 1 rating allow indefinite floor life at ≤30 °C/60% RH without baking or humidity-controlled storage.
What is the maximum steady-state power dissipation for the 1N5359E3/TR13 on a standard FR4 PCB?
When mounted on a standard FR4 PCB (1 oz Cu, 4 mm² copper pads, 1 mm track width, 25 mm length), the 1N5359E3/TR13 delivers 1.47 W steady-state power at 25 °C ambient. This derated value reflects its 85 °C/W junction-to-ambient thermal resistance under those specific board conditions.
How does the dynamic impedance of the 1N5359E3/TR13 affect voltage regulation performance?
The 1N5359E3/TR13 exhibits 3.5 Ω dynamic impedance (ZZ) at 50 mA test current, meaning its regulated voltage shifts less than 0.18 V between 10% and 50% of its maximum Zener current (75 mA). This low ZZ ensures minimal output variation under dynamic load changes in precision reference and protection circuits.
Is the 1N5359E3/TR13 suitable for automotive under-hood applications?
Yes - the 1N5359E3/TR13 is rated for –65 °C to +150 °C operating temperature and qualified per MIL-STD-750 for ESD immunity (Method 1020). Its T-18 axial package and 25 °C/W junction-to-lead thermal resistance support reliable operation in engine-control units and body control modules exposed to extreme thermal cycling and vibration.
