Product details
Overview
1N5360CE3/TR12 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 up to 110 mA maximum Zener current when adequately heat-sunk.
For engineers reviewing the 1N5360CE3/TR12 datasheet, 1N5360CE3/TR12 pinout, 1N5360CE3/TR12 application, or 1N5360CE3/TR12 equivalent, this page provides verified electrical parameters, thermal derating behavior, RoHS-compliant packaging details, and validated alternative parts for industrial power management designs.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias connection where the banded end is positive relative to the anode. Its 25 °C/W junction-to-lead thermal resistance enables 5 W dissipation at TL < 25°C with 3/8" lead length, while its 85 °C/W junction-to-ambient rating applies to FR4 PCB mounting with defined copper pad geometry.
The 1N5360CE3/TR12 exhibits 0.55 V maximum voltage regulation (ΔVZ) between 10% and 50% of IZM, and maintains ≤4.0 Ω dynamic impedance (ZZ) at 50 mA IZT - critical for low-noise, high-stability reference applications across -65°C to +150°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±2% at 50 mA - ensures tight reference accuracy for feedback control in regulated DC-DC converters. |
| Power Dissipation | 5.0 W at TL < 25°C - supports robust overvoltage clamping without external heatsink under lead-temperature-limited conditions. |
| Dynamic Impedance (ZZ) | 4.0 Ω max at IZT = 50 mA - minimizes output voltage variation under load transients in precision references. |
| Max Reverse Current (IR) | 0.5 μA at VR = 19 V - guarantees low leakage in high-impedance bias networks and sensing circuits. |
| Thermal Resistance | 25 °C/W junction-to-lead - enables predictable thermal design when mounted with 3/8" (10 mm) lead length from body. |
| Surge Current (IZSM) | 110 A peak (8.3 ms half-sine) - withstands transient overvoltage events such as ESD or inductive kickback. |
| Operating Temperature | -65°C to +150°C - suitable for automotive under-hood, industrial motor drives, and aerospace power systems. |
Pinout & Package
Package: Axial-leaded T-18 plastic encapsulated case per JEDEC DO-201AD standard; moisture sensitivity level 1 (no dry pack required); RoHS-compliant matte-tin plated leads; cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential node in reverse-bias regulation | Must be held at lower potential than cathode during Zener operation; defines reference ground reference point in shunt regulator topologies. |
| Cathode | Current exit terminal in forward bias; higher-potential terminal in reverse-bias regulation | Banded end; connects to regulated rail or error amplifier input; determines polarity of clamping action in overvoltage protection. |
Key Features
| Feature | Design Value |
|---|---|
| ±2% Zener voltage tolerance (C suffix) | Enables tighter closed-loop regulation without post-manufacturing trimming in power supply feedback paths. |
| e3 RoHS-compliant plating | Meets EU Directive 2011/65/EU and J-STD-020B Level 1 moisture sensitivity - eliminates dry-pack requirements and simplifies SMT reflow compatibility. |
| Low ΔVZ = 0.55 V | Reduces output voltage drift across 10–50% of IZM, improving stability in battery-powered instrumentation references. |
| High IZM = 110 mA | Supports higher shunt current capability in 24 V system protectors without derating, extending safe operating area under fault conditions. |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Eliminates need for on-board ESD protection circuitry in field-deployed industrial controllers and telecom line cards. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B | ±5% tolerance (B suffix), same VZ = 25 V, identical package and thermal specs | Lower accuracy acceptable in non-critical biasing or coarse overvoltage detection | Select when cost sensitivity outweighs need for ±2% regulation tightness. |

FAQ
What is the Zener voltage tolerance of the 1N5360CE3/TR12?
The 1N5360CE3/TR12 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its nominal 25 V Zener voltage falls within 24.5 V to 25.5 V at 50 mA test current and 25°C, enabling tighter regulation than ±5% (B suffix) or ±10% (A suffix) variants. This tolerance is confirmed in Microsemi's official 1N5333B–1N5388B datasheet revision D.
Does the 1N5360CE3/TR12 require dry packing before reflow soldering?
No, the 1N5360CE3/TR12 does not require dry packing prior to reflow soldering. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it is rated for unlimited floor life at ≤30°C/60% RH. The device uses void-free thermosetting epoxy encapsulation and RoHS-compliant matte-tin plating compatible with standard 260°C/10 s solder profiles.
What is the maximum steady-state power dissipation of the 1N5360CE3/TR12 on a standard FR4 PCB?
The 1N5360CE3/TR12 dissipates up to 1.47 W continuously when mounted on a standard FR4 PCB (1 oz Cu) with 4 mm² copper pads and 1 mm track width over 25 mm length. This value derives from its 85°C/W junction-to-ambient thermal resistance at TA = 25°C, as specified in the Microsemi datasheet Figure 1 derating curve and Maximum Ratings table.
How is polarity marked on the 1N5360CE3/TR12?
The 1N5360CE3/TR12 uses a cathode band to indicate polarity: the banded end is the cathode and must be connected to the higher-potential node during Zener operation. This marking aligns with JEDEC DO-201AD standards and is visible on the black epoxy body. Forward voltage is specified at 1.2 V max @ 1.0 A, confirming standard silicon PN junction behavior.
What does the "TR12" suffix indicate in 1N5360CE3/TR12?
The "TR12" suffix in 1N5360CE3/TR12 indicates tape-and-reel packaging per EIA-296 standard, with 12,000 units per reel. This format supports automated pick-and-place assembly and is distinct from bulk or ammo-pack options. The "e3" portion confirms RoHS compliance per EU Directive 2011/65/EU, verified in Microsemi's official documentation.
