Product details
Overview
1N5360C/TR8 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 at 50 mA test current with 4.0 Ω dynamic impedance and supports surge currents up to 110 A (8.3 ms half-sine).
For engineers reviewing the 1N5360C/TR8 datasheet, 1N5360C/TR8 pinout, 1N5360C/TR8 application, or 1N5360C/TR8 equivalent, key selection criteria include its tight ±2% VZ tolerance, low 4.0 Ω ZZ at IZT, 25 ºC/W junction-to-lead thermal resistance, and RoHS-compliant matte-tin plating compatible with 260 °C soldering.
Technical Context
This Zener operates in reverse breakdown mode with cathode band marking polarity; it requires the banded end to be held positive relative to the anode. Its regulation performance is specified at 25 °C lead temperature (TL), with voltage measured 40 ±10 ms after DC current application.
Thermal design must account for two distinct derating paths: 5.0 W at TL < 25 °C with 3/8″ (10 mm) lead length from body, or 1.47 W at TA = 25 °C on FR4 board (1 oz Cu, 4 mm² pads, 1 mm trace width). Dynamic impedance ZZ is measured using 1 kHz AC modulation at 10% of IZT.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±2% - precise reference voltage with minimal unit-to-unit variation for stable feedback control |
| Test Current (IZT) | 50 mA - operating point where VZ and ZZ are guaranteed per JEDEC registration |
| Dynamic Impedance (ZZ) | 4.0 Ω max - low AC resistance ensures minimal output voltage shift under load transients |
| Max Regulator Current (IZM) | 110 mA - maximum continuous DC current at rated power with adequate heat sinking |
| Surge Current (IZSM) | 110 A (8.3 ms half-sine) - withstands short-duration overvoltage events without failure |
| Voltage Regulation (ΔVZ) | 0.55 V - difference between VZ at 10% and 50% of IZM, indicating regulation linearity |
| Forward Voltage (VF) | 1.2 V max @ 1.0 A - low conduction loss when used in forward-biased clamp configurations |
Pinout & Package
Package: T-18 axial-leaded plastic encapsulated case per JEDEC TO-204AA; void-free UL94V-0 epoxy body; cathode indicated by colored band; leads plated with RoHS-compliant matte tin per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current sink in reverse bias | Connected to lower-potential node; forms regulated output reference when cathode is biased higher |
| Cathode | Current source in reverse bias | Banded end; connected to higher-potential node; defines regulated voltage drop across device |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance (C suffix) | Enables high-accuracy voltage references without external trimming or calibration |
| Moisture sensitivity Level 1 (IPC/JEDEC J-STD-020B) | Eliminates dry-pack requirement and bake-out prior to assembly |
| 25 ºC/W junction-to-lead thermal resistance | Supports 5 W dissipation with simple lead-length heat sinking (3/8″ from body) |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions and eliminates need for ESD-protective packaging during assembly |
| RoHS-compliant (e3 suffix) | Meets global environmental compliance requirements for commercial and industrial applications |

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/TR8 | ±5% VZ tolerance vs. ±2% for 1N5360C/TR8; identical package, IZT, ZZ, and thermal specs | Suitable where tighter regulation is not required; lower cost for non-critical references | Select 1N5360B/TR8 only if system-level accuracy budget permits ±5% reference drift |
| MMBZ5254B-TP | Surface-mount SOT-23 package; 24 V nominal VZ; ±5% tolerance; 0.25 W power rating | Used in space-constrained, low-power designs where 5 W dissipation is unnecessary | Choose MMBZ5254B-TP only for PCB area-limited applications accepting reduced power handling and looser tolerance |

FAQ
What is the Zener voltage tolerance of the 1N5360C/TR8?
The 1N5360C/TR8 has a Zener voltage tolerance of ±2%, as designated by the "C" suffix per Microsemi's documentation. 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. This tight tolerance enables use in applications demanding high reference accuracy without post-manufacturing calibration.
What does the "TR8" suffix indicate for the 1N5360C/TR8?
"TR8" indicates tape-and-reel packaging per EIA-296 standard, with 8 mm tape width and component orientation optimized for automated pick-and-place assembly. The 1N5360C/TR8 is supplied in this format to support high-volume SMT production, and the reel quantity is standardized per industry practice for axial-leaded T-18 devices.
Can the 1N5360C/TR8 be used in surface-mount designs?
No-the 1N5360C/TR8 is an axial-leaded T-18 package and is not compatible with surface-mount assembly. For SMT equivalents, Microsemi offers the SMBJ5360B series in DO-214AA (SMB) package. The 1N5360C/TR8 requires through-hole mounting with minimum 3/8″ (10 mm) lead length from body for full 5 W power dissipation.
What is the maximum steady-state power dissipation for the 1N5360C/TR8 on a standard FR4 PCB?
When mounted on a standard FR4 PCB (1 oz copper, 4 mm² pads, 1 mm trace width × 25 mm length), the 1N5360C/TR8 has a steady-state power rating of 1.47 W at 25 °C ambient temperature. This derated value reflects its 85 °C/W junction-to-ambient thermal resistance under those specific board conditions-not the full 5 W rating, which applies only with proper lead-length heat sinking.
Is the 1N5360C/TR8 RoHS compliant?
Yes-the 1N5360C/TR8 carries the "e3" designation per Microsemi's datasheet, confirming RoHS compliance with lead-free matte-tin plating on leads and halogen-free epoxy encapsulation. It meets EU Directive 2011/65/EU and is suitable for environmentally regulated commercial and industrial applications without exemption requests.
