Product details
Overview
1N5360C/TR12 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 industrial power supplies.
For engineers reviewing the 1N5360C/TR12 datasheet, 1N5360C/TR12 pinout, 1N5360C/TR12 application, or 1N5360C/TR12 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (110 A), voltage regulation (ΔVZ = 0.55 V), and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
The 1N5360C/TR12 functions as a two-terminal voltage regulator in reverse-biased mode, maintaining stable output across wide current (1.0–110 mA) and temperature (−65 °C to +150 °C) ranges. Its low dynamic impedance (4.0 Ω) and tight ±2% voltage tolerance ensure minimal deviation under load variation.
Designed for axial-lead through-hole mounting on FR4 PCBs with 1 oz copper, it delivers 5 W steady-state power at TL < 25 °C (3/8″ lead length) and 1.47 W at TA = 25 °C - enabled by 25 °C/W junction-to-lead and 85 °C/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±2% - precise regulation point for feedback loops and reference circuits |
| Test Current (IZT) | 50 mA - operating point where VZ and ZZ are specified |
| Dynamic Impedance (ZZ) | 4.0 Ω max at IZT - low AC resistance ensures stable voltage under transient load changes |

| Voltage Regulation (ΔVZ) | 0.55 V - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity |
| Surge Current (IZSM) | 110 A peak (8.3 ms half-sine) - withstands short-duration transients without failure |
| Thermal Resistance (RθJL) | 25 °C/W junction-to-lead - enables high-power operation with minimal heatsinking when leads serve as thermal path |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B/TR12 | ±5% tolerance (vs. ±2%), same VZ, IZT, ZZ, and package | Acceptable where tighter regulation not required; lower cost | Select 1N5360B/TR12 only if system-level testing confirms ±5% VZ meets reference stability targets |
| MMSZ5254ET1G | Surface-mount SOD-123, 500 mW, 24 V ±5%, 22 Ω ZZ | Not suitable for 5 W power dissipation; limited to low-current bias/reference roles | Choose MMSZ5254ET1G only for space-constrained PCBs where power demand is ≤0.5 W |
Compared with 1N5360C/TR12, the 1N5360B/TR12 offers identical form and function but relaxed tolerance, while MMSZ5254ET1G trades power capability and precision for miniaturization - neither is pin-compatible, and both require layout or thermal redesign.

FAQ
What is the Zener voltage tolerance of the 1N5360C/TR12?
The 1N5360C/TR12 has a Zener voltage tolerance of ±2%, as indicated by the "C" suffix per Microsemi's documentation. This means its nominal 25 V regulation point falls within 24.5 V to 25.5 V at 50 mA test current and 25 °C lead temperature. The tolerance is verified per JEDEC standards and applies across the full operating temperature range of −65 °C to +150 °C.
Does the 1N5360C/TR12 require dry packing before PCB assembly?
No, the 1N5360C/TR12 does not require dry packing. It carries IPC/JEDEC J-STD-020B moisture sensitivity Level 1 classification, meaning it can be stored and assembled without baking or humidity-controlled packaging. This simplifies logistics and eliminates pre-reflow bake cycles in manufacturing.
What is the maximum continuous current the 1N5360C/TR12 can handle at room temperature?
The 1N5360C/TR12 supports a maximum continuous Zener current (IZM) of 110 mA at 25 °C lead temperature (TL), corresponding to its 5 W power rating. When mounted on an FR4 board with standard copper pads, its derated steady-state power drops to 1.47 W, limiting usable current to approximately 59 mA at 25 °C ambient.
How is polarity marked on the 1N5360C/TR12?
The 1N5360C/TR12 uses a cathode band to indicate polarity: the banded end is the cathode and must be held at a higher potential than the anode to operate in Zener breakdown. During forward conduction, the device exhibits ≤1.2 V drop at 1.0 A - but its primary function is reverse-biased regulation, not rectification.
Is the 1N5360C/TR12 RoHS compliant?
Yes, the 1N5360C/TR12 is RoHS compliant, as confirmed by the "e3" suffix in its full manufacturer designation (1N5360C/TR12 e3). Its leads feature annealed matte-tin plating meeting RoHS requirements and remain fully solderable per MIL-STD-750 Method 2026, including compatibility with lead-free reflow profiles up to 260 °C for 10 seconds.
