Product details
Overview
1N5360B/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 (IZT), 4.0 Ω dynamic impedance (ZZ), and 110 mA maximum Zener current (IZM) at 25 °C lead temperature. It regulates voltage in power supply feedback loops, overvoltage protection circuits, and reference voltage generation.
For engineers reviewing the 1N5360B/TR12 datasheet, 1N5360B/TR12 pinout, 1N5360B/TR12 application, or 1N5360B/TR12 equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (25 °C/W junction-to-lead), surge current rating (110 A), low voltage regulation (ΔVZ = 0.55 V), and RoHS-compliant e3 marking compatibility.
Technical Context
This discrete Zener diode operates in reverse breakdown to maintain stable voltage across its terminals under varying load and line conditions. Its 25 V nominal Zener voltage is specified at 50 mA test current with 4.0 Ω dynamic impedance, ensuring minimal voltage deviation over regulated current range.
Designed for axial-lead mounting with T-18 package, it features 25 °C/W thermal resistance (junction-to-lead at 10 mm lead length), 0.7 g mass, and UL94V-0 void-free epoxy encapsulation. Cathode polarity is marked by a band; operation requires cathode positive relative to anode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±5% - precise regulation point for 24 V system references and clamping |
| Test Current (IZT) | 50 mA - standardized bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 4.0 Ω - low AC resistance ensures tight voltage stability under dynamic load changes |
| Max Zener Current (IZM) | 110 mA - maximum continuous DC current at TL = 25 °C with adequate heat sinking |
| Power Dissipation | 5.0 W at TL < 25 °C - defines thermal design margin for PCB layout and 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 - peak non-repetitive half-sine (8.3 ms) capability for transient suppression |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B (bulk) | Identical electrical specs; differs only in packaging (TR12 = tape-and-reel, bulk has no reel) | No functional difference; TR12 supports automated SMT placement, bulk supports manual/hand-soldered assembly | Select TR12 for high-volume production with pick-and-place; choose bulk for prototyping or low-run builds |
| MMBZ5252B (SOT-23) | Same 25 V ±5%, but 0.5 W rating, 100 Ω ZZ, and surface-mount package | Not suitable for 5 W dissipation; limited to low-power bias/reference roles where space is constrained | Use MMBZ5252B only when board space is critical and power < 0.5 W; retain 1N5360B/TR12 for full 5 W capability |
Compared with 1N5360B (bulk) and MMBZ5252B, the 1N5360B/TR12 uniquely combines JEDEC-standard axial-leaded form factor, 5 W power handling, and tape-and-reel automation readiness-making it optimal for industrial power supplies requiring field-proven reliability and manufacturability.

FAQ
What is the Zener voltage tolerance of the 1N5360B/TR12?
The 1N5360B/TR12 has a ±5% Zener voltage tolerance, confirmed by the "B" suffix per Microsemi's datasheet. This means its nominal 25 V regulation point falls within 23.75 V to 26.25 V when measured at 50 mA test current and 25 °C lead temperature. The tolerance is tighter than standard ±10% (A suffix) or ±20% (no suffix) variants, supporting higher-accuracy voltage references in the 1N5360B/TR12.
What is the maximum continuous Zener current for the 1N5360B/TR12?
The 1N5360B/TR12 supports a maximum continuous Zener current (IZM) of 110 mA at 25 °C lead temperature (TL), as specified in the Electrical Characteristics table. This rating assumes proper heat sinking-its 25 °C/W junction-to-lead thermal resistance allows safe operation at full 5 W dissipation only when TL remains ≤25 °C. Exceeding this current risks thermal runaway and permanent damage to the 1N5360B/TR12.
Does the 1N5360B/TR12 meet RoHS requirements?
Yes, the 1N5360B/TR12 is RoHS compliant, indicated by the "e3" suffix in its full manufacturer designation (1N5360B/TR12, e3). Its leads use annealed matte-tin plating instead of tin-lead, and its void-free thermosetting epoxy body meets UL94V-0 flammability standards-all verified in Microsemi's official documentation for the 1N5333B–1N5388B family, including the 1N5360B/TR12.
What is the voltage regulation (ΔVZ) specification for the 1N5360B/TR12?
The voltage regulation (ΔVZ) for the 1N5360B/TR12 is 0.55 V, defined as the difference between Zener voltage measured at 10% and 50% of its maximum Zener current (IZM). This parameter quantifies how tightly the 1N5360B/TR12 maintains regulation across its operating current range-lower ΔVZ indicates superior line regulation, critical for stable reference and clamp performance in the 1N5360B/TR12.
How is polarity marked on the 1N5360B/TR12?
The 1N5360B/TR12 uses a cathode band-a single colored stripe near one end of the axial body-to indicate polarity. The banded end is the cathode and must be held at a higher potential than the unmarked (anode) end during normal Zener operation. This marking is consistent across the entire 1N5333B–1N5388B series and is essential for correct installation in voltage regulation or clamping circuits using the 1N5360B/TR12.
