Product details
Overview
1N5360BE3/TR8 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 25 V, ±5% tolerance (B suffix), maximum dynamic impedance of 4.0 Ω at 50 mA test current, and maximum reverse current of 0.5 μA at 19 V. It operates from –65 °C to +150 °C and is used for precision voltage reference and overvoltage protection in industrial power supplies.
For engineers reviewing the 1N5360BE3/TR8 datasheet, 1N5360BE3/TR8 pinout, 1N5360BE3/TR8 application, or 1N5360BE3/TR8 equivalent, key selection criteria include Zener voltage accuracy, 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 functions as a two-terminal voltage regulator operating in reverse breakdown. Its Zener voltage is specified at 25 °C with 50 mA test current (IZT), and it maintains stable regulation across 10–50% of IZM (110 mA) with ΔVZ ≤ 0.55 V.
Thermal design relies on lead-length-dependent dissipation: 5.0 W at TL = 25 °C with 3/8″ (10 mm) lead length, derating linearly above 25 °C. Junction-to-ambient thermal resistance is 85 °C/W when mounted on FR4 with defined copper pad geometry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±5% - precise regulation point for 24 V rail clamping and reference generation |
| Test Current (IZT) | 50 mA - standardized bias point for VZ measurement and impedance characterization |
| Dynamic Impedance (ZZ) | 4.0 Ω max at IZT - low AC impedance ensures minimal output voltage variation under load transients |
| Max Reverse Current (IR) | 0.5 μA at VR = 19 V - ultra-low leakage preserves regulation integrity in high-impedance bias networks |
| Max Regulator Current (IZM) | 110 mA - maximum continuous DC current before thermal limit at TL = 25 °C |
| Surge Current (IZSM) | 110 A (8.3 ms half-sine) - withstands transient overvoltage events without degradation |
| Voltage Regulation (ΔVZ) | 0.55 V - difference between VZ measured at 10% and 50% of IZM, indicating regulation linearity |
Pinout & Package
Package: Axial-leaded T-18 plastic case (void-free UL94V-0 epoxy), cathode indicated by band; leads plated with RoHS-compliant matte tin per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / low-voltage side in regulation mode | Connected to circuit ground or lower-potential node during Zener operation |
| Cathode | Reverse-biased regulation terminal / high-voltage side in regulation mode | Banded end; connected to input rail to clamp voltage at 25 V relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered 5 W Zener | Industry-standard footprint and reliability for legacy and new designs requiring axial mounting |
| Moisture Sensitivity Level 1 | No dry pack required - simplifies handling and eliminates bake-out prior to assembly |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Robust handling in standard manufacturing environments without special ESD controls |
| RoHS-compliant (e3 suffix) | Lead-free matte-tin plating meets EU RoHS Directive 2011/65/EU and JEDEC J-STD-609A Class 1 |

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); no TR8 designation | Lacks tape-and-reel convenience for automated SMT placement; suitable for manual or wave-solder assembly | Select when reel packaging is unnecessary and cost-per-unit is prioritized over placement compatibility |
| SMBJ5360B | Surface-mount SMB package version; same electrical specs but 125 °C/W junction-to-ambient thermal resistance | Requires PCB layout revision; not drop-in compatible due to footprint and thermal path differences | Choose only when board space constraints mandate SMT and thermal management accommodates higher RθJA |
Compared with 1N5360BE3/TR8, 1N5360BRLG offers identical performance in bulk form but lacks tape-and-reel logistics, while SMBJ5360B provides surface-mount compatibility at the expense of thermal performance and mechanical fit-neither is pin-compatible, and both require design validation for replacement.

FAQ
What is the Zener voltage tolerance of the 1N5360BE3/TR8?
The 1N5360BE3/TR8 has a Zener voltage tolerance of ±5%, indicated 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 25 °C with 50 mA test current. The e3 suffix confirms RoHS compliance, and TR8 denotes tape-and-reel packaging with 8 mm carrier tape.
How much power can the 1N5360BE3/TR8 dissipate continuously?
The 1N5360BE3/TR8 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. Derating is linear above 25 °C at 20 mW/°C, yielding ~1.47 W at 25 °C ambient when mounted on FR4 with specified copper pads per datasheet Figure 1.
What is the maximum reverse leakage current for the 1N5360BE3/TR8?
The 1N5360BE3/TR8 exhibits a maximum reverse current (IR) of 0.5 μA when tested at 19 V (VR), which is 76% of its nominal 25 V Zener voltage. This ultra-low leakage supports high-impedance biasing and minimizes quiescent power loss in precision reference circuits.
Does the 1N5360BE3/TR8 require dry packing before reflow soldering?
No, the 1N5360BE3/TR8 has a moisture sensitivity level (MSL) of Level 1 per IPC/JEDEC J-STD-020B, meaning it is not moisture-sensitive and requires no dry pack or baking prior to soldering. Its void-free thermosetting epoxy body and matte-tin plating ensure reliable solderability under standard reflow profiles up to 260 °C for 10 seconds.
Can the 1N5360BE3/TR8 be used for transient voltage suppression?
Yes-the 1N5360BE3/TR8 is rated for a non-recurrent surge current (IZSM) of 110 A (8.3 ms half-sine waveform), making it suitable for clamping short-duration transients in 24 V systems. However, it is not optimized for repetitive ESD events like dedicated TVS diodes; its primary function remains precision DC voltage regulation.
