Product details
Overview
1N5360E3/TR8 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 25 V, ±5% tolerance (B-suffix equivalent), 50 mA test current, 4.0 Ω maximum dynamic impedance at IZT, and 110 mA maximum Zener current (IZM) when adequately heat-sunk. It serves as a precision voltage reference or shunt regulator in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1N5360E3/TR8 datasheet, 1N5360E3/TR8 pinout, 1N5360E3/TR8 application, or 1N5360E3/TR8 equivalent, key selection criteria include its 25 V Zener voltage, 5 W steady-state power rating at TL < 25°C, 25 °C/W junction-to-lead thermal resistance, RoHS-compliant matte-tin plating, and T-18 axial package compatibility with through-hole PCB assembly.
Technical Context
The 1N5360E3/TR8 operates as a shunt-regulating device where reverse-biased conduction maintains stable voltage across load terminals. Its Zener voltage is specified at 25°C with 50 mA test current and exhibits 4.0 Ω dynamic impedance (ZZ) under those conditions, ensuring low voltage variation with current changes.
Designed for high-reliability DC voltage stabilization, it supports operation from –65°C to +150°C, withstands 8.3 ms non-recurring surge currents up to 110 A, and delivers 0.55 V maximum voltage regulation (ΔVZ) between 10% and 50% of IZM - critical for tight-tolerance analog references and feedback sensing.
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 - defined operating point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 4.0 Ω max at IZT - ensures minimal output voltage shift under load current transients |
| Max Zener Current (IZM) | 110 mA - maximum continuous DC current before thermal runaway when lead-temperature limited to 25°C |
| Power Dissipation | 5.0 W at TL < 25°C (3/8″ lead length) - requires heatsinking for sustained full-power operation |
| Thermal Resistance | 25 °C/W junction-to-lead - enables predictable temperature rise with known lead-mount thermal path |
| Voltage Regulation (ΔVZ) | 0.55 V max - difference between VZ measured at 11 mA and 55 mA, defining line regulation capability |
| Surge Current (IZSM) | 110 A peak (8.3 ms half-sine) - supports transient overvoltage suppression without failure |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B | Same 25 V ±5%, 5 W rating, but non-RoHS tin-lead plating; no e3 suffix | Not suitable for RoHS-compliant production; otherwise identical electrical and thermal performance | Select 1N5360B only if legacy tin-lead assembly process is used and RoHS exemption applies |
| MMBZ5254B (SOT-23) | 25 V ±5%, but 0.35 W power rating, surface-mount package, higher ZZ (25 Ω) | Limited to low-current biasing or signal-level clamping; cannot replace 1N5360E3/TR8 in 5 W power regulation | Choose MMBZ5254B only for space-constrained, low-power applications where thermal mass and surge capability are not required |
Compared with 1N5360B and MMBZ5254B, the 1N5360E3/TR8 uniquely combines RoHS compliance, 5 W power handling, 25 °C/W thermal resistance, and 110 A surge rating - making it the sole choice for industrial-grade through-hole shunt regulation requiring both reliability and regulatory conformance.

FAQ
What is the Zener voltage tolerance of the 1N5360E3/TR8?
The 1N5360E3/TR8 has a Zener voltage tolerance of ±5%, confirmed by its "B" suffix in the base part number (1N5360B) and documented in Microsemi's REV D datasheet. This tolerance applies at 25°C with 50 mA test current and defines the allowable deviation from the nominal 25 V regulation point across manufacturing lots and operating conditions.
Does the 1N5360E3/TR8 require dry packing before PCB assembly?
No, the 1N5360E3/TR8 does not require dry packing. It is rated at Moisture Sensitivity Level 1 per IPC/JEDEC J-STD-020B, meaning it can be stored and assembled without baking or humidity-controlled packaging - simplifying logistics and eliminating pre-reflow moisture mitigation steps.
What is the maximum surge current rating for the 1N5360E3/TR8?
The 1N5360E3/TR8 is rated for a maximum non-recurring surge current (IZSM) of 110 A, defined as the peak value of an 8.3 ms half-sine waveform. This rating is validated per Microsemi's test methodology and enables reliable transient suppression in industrial power rails subject to inductive switching events.
Can the 1N5360E3/TR8 be used in surface-mount designs?
No, the 1N5360E3/TR8 is an axial-leaded T-18 package intended for through-hole mounting. For surface-mount equivalents, Microsemi offers the SMBJ5360B or SMBG5360B in DO-214AA (SMB) or DO-214AB (SMBG) packages - which share the same 25 V ±5% regulation but differ in thermal and mechanical characteristics.
What is the forward voltage specification for the 1N5360E3/TR8?
The forward voltage (VF) of the 1N5360E3/TR8 is specified at ≤1.2 V when conducting 1.0 A in forward bias. This parameter is relevant for polarity protection or reverse-connection safeguard circuits where the device may conduct in forward direction during fault conditions.
