Product details
Overview
1N5360BE3/TR12 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 25 V, ±5% tolerance (B suffix), 50 mA test current, 4.0 Ω maximum dynamic impedance at IZT, and 110 mA maximum Zener current (IZM) when adequately heat-sunk. It regulates voltage in power supply feedback loops and overvoltage protection circuits across industrial and telecom equipment.
For engineers reviewing the 1N5360BE3/TR12 datasheet, 1N5360BE3/TR12 pinout, 1N5360BE3/TR12 application, or 1N5360BE3/TR12 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (110 A), reverse leakage performance at VR = 18 V, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device operates as a voltage reference and shunt regulator in DC power systems, maintaining stable output by conducting reverse current above its specified Zener breakdown threshold. Its low dynamic impedance (4.0 Ω) ensures minimal voltage variation across 10–50% of IZM, and its 25 °C/W thermal resistance enables reliable 5 W dissipation with 3/8″ lead length heat sinking.
The 1N5360BE3/TR12 features a void-free thermosetting epoxy T-18 package rated for -65 °C to +150 °C operation, cathode band polarity marking, and compliance with IPC/JEDEC J-STD-020B Level 1 moisture sensitivity-no dry pack required. It withstands 8.3 ms half-sine surge currents up to 110 A and exhibits ≤0.55 V voltage regulation (ΔVZ) between 10% and 50% of IZM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±5% - precise regulation point for 24 V system references and clamp thresholds |
| Test Current (IZT) | 50 mA - operating point where VZ and ZZ are specified; defines stable bias condition |
| Dynamic Impedance (ZZ) | 4.0 Ω max - low AC resistance ensures tight voltage control under varying load current |
| Max Zener Current (IZM) | 110 mA - maximum continuous DC current at TL = 25 °C with proper heat sinking |
| Surge Current (IZSM) | 110 A - peak non-repetitive 8.3 ms half-sine capability for transient suppression |
| Voltage Regulation (ΔVZ) | 0.55 V max - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity |
| Reverse Leakage (IR) | 0.5 μA max at VR = 18 V - low off-state current preserves efficiency in high-impedance bias networks |
Pinout & Package
Package: Axial-leaded T-18 plastic case (JEDEC DO-201AD), void-free UL94V-0 epoxy body, tin-lead or RoHS-compliant matte-tin plated leads, cathode indicated by colored band.

| Anode | Forward conduction terminal / low-voltage reference node | Connected to circuit ground or lower-potential rail in shunt regulator configuration |
| Cathode | Zener breakdown terminal / regulated output node | Banded end; connected to input rail or feedback node; maintains 25 V relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance (B suffix) | Enables accurate 25 V regulation without post-calibration in cost-sensitive power supplies |
| 25 °C/W junction-to-lead thermal resistance | Supports full 5 W dissipation with simple 3/8″ lead-length heatsinking-no PCB copper pour required |
| RoHS-compliant e3 suffix | Meets global environmental regulations with annealed matte-tin plating solderable per MIL-STD-750 |
| Level 1 moisture sensitivity | Eliminates dry-pack requirement and floor-life constraints-ready for standard SMT/reflow or hand-soldering |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Reduces handling precautions and eliminates need for special ESD workstations during assembly |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360BRLG | Same 25 V ±5%, 5 W rating, but in bulk packaging (no tape/reel); identical electrical specs and T-18 package | No TR12 tape-and-reel format-requires manual loading or different feeder setup | Select when prototyping or low-volume production avoids reel logistics |
| MMSZ5254ET1G | Surface-mount SOD-123 package; 25 V ±5%, but only 500 mW rating and higher ZZ (30 Ω) | Not suitable for 5 W continuous dissipation; limited to low-power bias/reference roles | Select only for space-constrained PCBs where thermal design supports <0.5 W operation |
Compared with 1N5360BE3/TR12, 1N5360BRLG offers identical performance in bulk form, while MMSZ5254ET1G provides footprint reduction at the cost of 90% power derating and degraded regulation stability.

FAQ
What is the Zener voltage tolerance of the 1N5360BE3/TR12?
The 1N5360BE3/TR12 has a Zener voltage tolerance of ±5%, indicated by the "B" suffix in its part number. This means its actual regulation voltage falls between 23.75 V and 26.25 V at 50 mA test current and 25 °C lead temperature. The e3 suffix confirms RoHS compliance, and TR12 denotes tape-and-reel packaging per EIA-296 standards. This tolerance enables repeatable performance in feedback and clamp circuits without calibration.
How much power can the 1N5360BE3/TR12 dissipate continuously?
The 1N5360BE3/TR12 is rated for 5.0 W steady-state power dissipation at a lead temperature (TL) of 25 °C with 3/8″ (10 mm) lead length from the body. When mounted on a standard FR4 PCB with 1 oz copper, its derated power drops to 1.47 W at 25 °C ambient due to higher junction-to-ambient thermal resistance (85 °C/W). Full 5 W operation requires external heat sinking or lead-forming for thermal conduction.
What is the maximum surge current rating for the 1N5360BE3/TR12?
The 1N5360BE3/TR12 has a maximum non-repetitive surge current (IZSM) of 110 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating applies under single-event transient conditions such as lightning-induced surges or inductive kickback. The device maintains regulation integrity during such events, clamping voltage to no more than 25.55 V (25 V + 0.55 V ΔVZ) while safely dissipating the surge energy.
Does the 1N5360BE3/TR12 require dry packing before PCB assembly?
No, the 1N5360BE3/TR12 does not require dry packing prior to assembly. It carries IPC/JEDEC J-STD-020B moisture sensitivity level 1, meaning it is not hygroscopic and poses no popcorning risk during reflow. The void-free thermosetting epoxy package is inherently moisture-resistant, allowing indefinite floor life and standard handling without baking or humidity-controlled storage.
What is the reverse leakage current specification for the 1N5360BE3/TR12?
The 1N5360BE3/TR12 specifies a maximum reverse leakage current (IR) of 0.5 μA at a reverse test voltage (VR) of 18 V. This low leakage ensures minimal power loss in high-impedance bias networks and preserves accuracy in precision reference applications. The value is measured at 25 °C and reflects the device's ability to remain effectively open-circuit below its 25 V Zener threshold.
