Product details
Overview
1N5360E3/TR13 from Microsemi is a 25 V, ±5% tolerance, 5 W axial-leaded silicon Zener diode optimized for voltage regulation in power supply feedback loops, overvoltage protection circuits, and precision reference applications. It delivers 4.3 V forward voltage at 1.0 A, supports 110 mA maximum Zener current (IZM), and maintains low dynamic impedance of 4.0 Ω at 50 mA test current.
For engineers reviewing the 1N5360E3/TR13 datasheet, 1N5360E3/TR13 pinout, 1N5360E3/TR13 application, or 1N5360E3/TR13 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
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 regulation performance is specified at TL = 25 °C with 50 mA test current (IZT), and it exhibits minimal voltage drift across temperature (–65 °C to +150 °C operating range).
The 1N5360E3/TR13 uses void-free thermosetting epoxy encapsulation (UL94V-0), achieves moisture sensitivity level 1 per J-STD-020B (no dry pack required), and is rated for 260 °C soldering (10 s max). Its 0.7 g mass and T-18 axial package support through-hole mounting on FR4 PCBs with 1 oz copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±5% - precise regulation point for feedback networks and clamp thresholds |
| Power Dissipation | 5.0 W at TL < 25 °C (3/8″ lead length) - requires heat sinking above ambient derating limits |
| Test Current (IZT) | 50 mA - standardized bias point for VZ and ZZ measurement |
| Dynamic Impedance (ZZ) | 4.0 Ω @ IZT - low AC impedance ensures stable regulation under varying load current |
| Max Reverse Current (IR) | 0.5 μA @ VR = 19 V - tight leakage enables high-impedance reference stability |
| Voltage Regulation (ΔVZ) | 0.55 V - difference between VZ measured at 10% and 50% of IZM, indicating knee sharpness |
| Surge Current (IZSM) | 110 A (8.3 ms half-sine) - withstands transient overvoltage events without degradation |
| Thermal Resistance | 25 °C/W junction-to-lead - enables predictable thermal design with standard lead heatsinking |
Pinout & Package
Package: T-18 axial-leaded plastic case (void-free UL94V-0 epoxy), 0.7 g weight, cathode indicated by band. Leads are annealed matte-tin plated (RoHS compliant, solderable per MIL-STD-750 Method 2026).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Current entry terminal in forward bias; reference ground node in reverse-bias regulation | Connected to system ground or low-side return path; defines reference potential for regulated output |
| Cathode (banded end) | Current exit terminal in forward bias; regulated voltage node in reverse bias | Connected to feedback node or protected rail; supplies stable 25 V reference when reverse-biased |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures cross-manufacturer compatibility and standardized test conditions per JEDEC JESD24 |
| ±5% voltage tolerance (B suffix) | Reduces calibration overhead in mid-precision power supply designs versus ±10% or ±20% variants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B | No e3 RoHS suffix; tin-lead plating instead of matte-tin; identical electrical specs | Not suitable for lead-free assembly processes requiring Pb-free solder compatibility | Select 1N5360B only for legacy SnPb reflow or non-RoHS-compliant programs |
| MMSZ5254ET1G | Surface-mount SOD-123 package; 25 V ±5%; 500 mW rating; higher ZZ (30 Ω) | Limited to low-power signal-level regulation; cannot replace 1N5360E3/TR13 in 5 W power stages | Choose MMSZ5254ET1G only for space-constrained PCBs where thermal dissipation ≤0.5 W is sufficient |
Compared with 1N5360B and MMSZ5254ET1G, the 1N5360E3/TR13 uniquely combines 5 W power handling, axial-leaded mechanical robustness, RoHS compliance, and 25 °C/W thermal resistance-making it optimal for industrial power supply and protection designs requiring field-replaceable through-hole components.

FAQ
What is the Zener voltage tolerance of the 1N5360E3/TR13?
The 1N5360E3/TR13 has a Zener voltage tolerance of ±5%, denoted by the "B" suffix in its part number. This means its nominal 25 V regulation point falls within 23.75 V to 26.25 V at 50 mA test current and 25 °C lead temperature. The e3 suffix confirms RoHS compliance but does not affect voltage tolerance.
How is the 1N5360E3/TR13 mounted and what are its thermal limitations?
The 1N5360E3/TR13 uses axial T-18 leads for through-hole mounting. Its thermal resistance is 25 °C/W junction-to-lead at 3/8″ (10 mm) lead length from body. When mounted on FR4 with 1 oz copper, thermal resistance rises to 85 °C/W junction-to-ambient. Derating begins above 25 °C lead temperature per Figure 1 in the datasheet.
Does the 1N5360E3/TR13 support lead-free soldering processes?
Yes-the e3 suffix certifies that the 1N5360E3/TR13 features RoHS-compliant annealed matte-tin plating, qualified for lead-free reflow up to 260 °C for 10 seconds. It meets J-STD-020B Level 1 moisture sensitivity, eliminating pre-bake requirements before assembly.
What is the maximum Zener current (IZM) for the 1N5360E3/TR13 and how is it calculated?
The 1N5360E3/TR13 has a maximum Zener current (IZM) of 110 mA at TL = 25 °C. This value is derived from P = VZM × IZM, where VZM = 26.25 V (upper limit of 25 V ±5%) and P = 5.0 W. IZM decreases linearly with rising lead temperature per the derating curve in Figure 1.
Can the 1N5360E3/TR13 be used as a direct replacement for the 1N5360B?
Yes-electrically and mechanically, the 1N5360E3/TR13 is identical to the 1N5360B except for plating: the E3 version uses RoHS-compliant matte-tin, while the B version uses tin-lead. Both share identical Zener voltage, power rating, thermal resistance, and package dimensions. No PCB changes are needed for substitution in compatible assembly processes.
