Product details
Overview
1N5360CE3/TR8 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 25 V, ±2% tolerance (C suffix), 50 mA test current, and 4.0 Ω maximum dynamic impedance at IZT. 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 1N5360CE3/TR8 datasheet, 1N5360CE3/TR8 pinout, 1N5360CE3/TR8 application, or 1N5360CE3/TR8 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (110 A), 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 Zener voltage is specified at 25 °C with 50 mA DC test current and exhibits 4.0 Ω dynamic impedance (ZZ) under those conditions, ensuring stable regulation across load variations.
It features a T-18 axial package with cathode band marking, void-free UL94V-0 epoxy body, and is rated for 5.0 W steady-state dissipation at TL < 25 °C with 3/8″ lead length. Thermal resistance is 25 °C/W junction-to-lead or 85 °C/W junction-to-ambient on FR4 board.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Test Current (IZT) | 50 mA - defined operating point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 4.0 Ω max - low AC resistance ensures minimal voltage deviation under varying load currents |
| Max Regulator Current (IZM) | 110 mA - maximum continuous DC current at 25 °C before exceeding 5 W power limit |
| Surge Current (IZSM) | 110 A - peak non-repetitive half-sine (8.3 ms) capability for transient overvoltage clamping |
| Thermal Resistance (RθJL) | 25 °C/W - enables high-current operation with simple lead-based heat sinking |
| Reverse Leakage (IR) | 0.5 μA max at 20.1 V - negligible standby current in high-impedance bias networks |
Pinout & Package

FAQ
What is the Zener voltage tolerance of the 1N5360CE3/TR8?
The 1N5360CE3/TR8 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its actual regulation voltage falls between 24.5 V and 25.5 V at 25 °C with 50 mA test current. This tight tolerance supports precision feedback and reference applications where calibration drift must be minimized across temperature and aging.
Does the 1N5360CE3/TR8 require dry packing before PCB assembly?
No, the 1N5360CE3/TR8 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it can be stored indefinitely at ambient conditions without desiccant or dry cabinet. This simplifies inventory handling and eliminates floor-life tracking during manual or wave solder assembly processes.
What is the maximum continuous current the 1N5360CE3/TR8 can handle at room temperature?
The 1N5360CE3/TR8 supports a maximum continuous Zener current (IZM) of 110 mA at 25 °C lead temperature (TL), corresponding to its 5.0 W power rating. This assumes 3/8″ (10 mm) lead length from the body for heat conduction. Derating applies above 25 °C per Figure 1 in the datasheet.
Can the 1N5360CE3/TR8 be used as a replacement for the 1N5360B?
Yes, the 1N5360CE3/TR8 is functionally compatible with the 1N5360B in most circuits, sharing identical 25 V nominal Zener voltage and 50 mA test current. However, the 1N5360CE3/TR8 offers tighter ±2% tolerance and RoHS-compliant plating, while the 1N5360B has ±5% tolerance and tin-lead leads. No PCB changes are needed, but verify compliance requirements and thermal margin.
What is the surge current rating of the 1N5360CE3/TR8 and how is it defined?
The 1N5360CE3/TR8 has a maximum non-repetitive surge current (IZSM) of 110 A, defined as the peak value of a single 8.3 ms half-sine waveform. This rating reflects its ability to absorb transient energy-such as inductive kickback or lightning-induced surges-without permanent degradation, making it suitable for clamp protection in relay and solenoid drive circuits.
