Product details
Overview
1N5360CE3/TR13 from Microsemi is a 25 V, ±2% tolerance, 5 W axial-leaded silicon Zener diode optimized for precision voltage regulation in power supply feedback loops, overvoltage protection circuits, and reference voltage generation. It delivers stable regulation across 10–50% of its maximum Zener current (IZM = 110 mA), with low dynamic impedance (4.0 Ω at IZT = 50 mA) and minimal voltage drift (ΔVZ = 0.55 V).
For engineers reviewing the 1N5360CE3/TR13 datasheet, 1N5360CE3/TR13 pinout, 1N5360CE3/TR13 application, or 1N5360CE3/TR13 equivalent, key selection criteria include Zener voltage tolerance (±2%), thermal resistance (25 °C/W junction-to-lead), surge current rating (110 A), RoHS-compliant matte-tin plating, and tape-and-reel packaging (TR13).
Technical Context
This device operates as a two-terminal voltage reference, conducting in reverse breakdown to clamp voltage at 25 V ±2% when reverse-biased above its knee voltage. Its design supports stable regulation under varying load and temperature conditions, with specified performance at TL = 25 °C and derated power above that temperature.
The 1N5360CE3/TR13 uses a void-free thermosetting epoxy case (UL94V-0), cathode-indicated band polarity, and is rated for -65 °C to +150 °C operation. It withstands 8.3 ms non-repetitive surge currents up to 110 A and exhibits low voltage regulation (ΔVZ = 0.55 V) between 10% and 50% of IZM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±2% - precise reference point for feedback or clamping at nominal 25 V |
| Test Current (IZT) | 50 mA - standardized bias point for measuring VZ and ZZ |
| Dynamic Impedance (ZZ) | 4.0 Ω - low AC resistance ensures minimal voltage shift under dynamic load changes |
| Max Regulator Current (IZM) | 110 mA - maximum continuous DC current at 25 °C lead temperature |
| Power Dissipation | 5.0 W at TL < 25 °C (3/8" lead length) - defines thermal design margin for heatsinking |
| Voltage Regulation (ΔVZ) | 0.55 V - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity |
| Surge Current (IZSM) | 110 A (8.3 ms half-sine) - peak transient capability for overvoltage event suppression |
Pinout & Package

| RoHS-compliant matte-tin plating (e3) | Ensures solderability and reliability under Pb-free reflow profiles (260 °C/10 s max) |
| Moisture sensitivity Level 1 (J-STD-020B) | Eliminates dry-pack requirement and floor-life constraints, enabling immediate use after opening |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions during assembly and testing in standard environments |
Applications
| Switch-Mode Power Supply Feedback | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Used in the optocoupler feedback path of an isolated DC-DC converter to regulate output voltage. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 25 V threshold for error amplifier comparison. Use Value: ±2% tolerance ensures output regulation within ±1% over line/load/temperature, meeting industrial PSU specs. | Use Scenario: Placed across a 24 V DC bus to protect downstream logic from transients exceeding 26.5 V.

IC Role / Device Role / Timing Role: Precision bias source maintaining constant bridge voltage despite supply ripple. Use Value: Stable VZ over -40 °C to +85 °C enables <0.05%/°C drift in bridge output calibration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B | Same 25 V nominal, but ±5% tolerance (B suffix) and higher ZZ (6.0 Ω) | Acceptable where tighter regulation not required; lower cost for non-critical rails | Select 1N5360B if ±5% tolerance suffices and cost optimization is prioritized over regulation linearity |
| MMSZ5254ET1G | Surface-mount SOD-123 package, 24 V ±5%, 500 mW rating, 22 Ω ZZ | Not drop-in; requires PCB redesign; limited to low-power signal-level references | Choose MMSZ5254ET1G only for space-constrained, low-current (<10 mA) applications where axial leads are impractical |
Compared with 1N5360B and MMSZ5254ET1G, the 1N5360CE3/TR13 provides superior voltage accuracy (±2% vs. ±5%), lower dynamic impedance (4.0 Ω vs. 6.0 Ω or 22 Ω), and full 5 W power handling-making it optimal for industrial-grade power regulation where stability and surge resilience are critical.

FAQ
What is the Zener voltage tolerance of the 1N5360CE3/TR13?
The 1N5360CE3/TR13 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 25 V Zener voltage is guaranteed between 24.5 V and 25.5 V at 50 mA test current and 25 °C lead temperature, supporting tighter regulation than ±5% (B) or ±10% (A) variants.
How does the 1N5360CE3/TR13 handle thermal dissipation?
The 1N5360CE3/TR13 features a junction-to-lead thermal resistance of 25 °C/W, allowing full 5 W power dissipation when leads are heat-sunk at 3/8" (10 mm) from the body at ≤25 °C. On FR4 PCBs with 4 mm² copper pads, its steady-state rating drops to 1.47 W at 25 °C ambient-requiring careful thermal layout for sustained operation.
Is the 1N5360CE3/TR13 RoHS compliant?
Yes, the 1N5360CE3/TR13 is RoHS compliant, confirmed by the "e3" suffix in its part number. Its matte-tin-plated leads meet Pb-free soldering requirements, including compatibility with 260 °C/10 s reflow profiles per MIL-STD-750 Method 2026.
What is the maximum surge current rating for the 1N5360CE3/TR13?
The 1N5360CE3/TR13 is rated for a maximum non-repetitive surge current (IZSM) of 110 A, defined as the peak of an 8.3 ms half-sine waveform. This rating enables robust transient suppression in industrial power rails without device failure under short-duration overvoltage events.
Can the 1N5360CE3/TR13 be used in surface-mount designs?
No-the 1N5360CE3/TR13 is an axial-leaded T-18 package and is not surface-mount compatible. For SMT equivalents, Microsemi offers the SMBJ5360B (DO-214AA) and SMBG5360B (DO-214AB), though neither matches the ±2% tolerance or identical electrical specs of the 1N5360CE3/TR13.
