Product details
Overview
1N5360AE3/TR8 from Microsemi is a 5 W axial-leaded silicon Zener diode with nominal regulation voltage of 25 V, ±10% tolerance (A 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 across industrial power supplies and voltage reference circuits operating from -65°C to +150°C.
For engineers reviewing the 1N5360AE3/TR8 datasheet, 1N5360AE3/TR8 pinout, 1N5360AE3/TR8 application, or 1N5360AE3/TR8 equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (25 °C/W junction-to-lead), surge current rating (110 A), reverse leakage performance at VR = 20.1 V, and RoHS-compliant matte-tin plating per MIL-STD-750.
Technical Context
This device operates as a voltage reference or shunt regulator in DC power conditioning circuits, maintaining stable output voltage under varying load and line conditions. Its low dynamic impedance (4.0 Ω) and tight voltage regulation (ΔVZ = 0.55 V) ensure minimal deviation between 10% and 50% of IZM.
The 1N5360AE3/TR8 features a T-18 axial package with cathode band marking, void-free UL94V-0 epoxy body, and lead termination compatible with 260 °C/10 s soldering. It delivers 5.0 W steady-state power at TL < 25 °C with 3/8″ (10 mm) lead length from body.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 25 V ±10% - defines nominal regulation point; high-end VZM = 27.5 V sets IZM calculation basis |
| Test Current (IZT) | 50 mA - standardized bias point for measuring VZ and ZZ; ensures repeatable characterization |
| Dynamic Impedance (ZZ) | 4.0 Ω max at IZT - determines output voltage variation under load transients |
| Max Zener Current (IZM) | 110 mA - maximum continuous DC current at TL = 25 °C; derates linearly above 25 °C |
| Surge Current (IZSM) | 110 A peak - withstands non-repetitive 8.3 ms half-sine surges, critical for input protection |
| Thermal Resistance | 25 °C/W junction-to-lead - enables 5 W dissipation with modest heatsinking at lead termination |
| Reverse Leakage (IR) | 0.5 μA max at VR = 20.1 V - ensures low standby power loss in high-impedance reference nodes |
Pinout & Package
Package: T-18 axial-leaded plastic encapsulated case per JEDEC DO-204AL. Cathode identified by single black band; operated with banded end positive relative to unbanded end. Moisture sensitivity level 1 - no dry pack required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; establishes return path for Zener current |
| Cathode (banded end) | Regulated output node | Provides stable 25 V reference when reverse-biased; sinks current into load |
Key Features
| Feature | Design Value |
|---|---|
| JEDEC-registered Zener family | Ensures mechanical and electrical interchangeability across qualified suppliers and legacy designs |
| RoHS-compliant matte-tin plating | Meets IPC/JEDEC J-STD-020B Level 1 moisture sensitivity without dry-pack requirement |
| Low thermal resistance (25 °C/W) | Enables full 5 W power dissipation with simple lead-frame heatsinking - no PCB copper pour needed |
| Nonsensitive to ESD (MIL-STD-750 Method 1020) | Eliminates need for on-board ESD protection during handling and assembly |
| High surge current rating (110 A) | Protects downstream circuitry against transient overvoltage events without external TVS |
Applications
| Industrial Power Supply Reference | Overvoltage Clamp Circuit |
|---|---|
Use Scenario: Stabilizing feedback voltage in isolated DC-DC converter secondary-side regulation. IC Role / Device Role / Timing Role: Shunt voltage reference providing precise 25 V setpoint to optocoupler feedback network.

| Programmable Logic Controller Input Conditioning | Analog Sensor Signal Conditioning |
Use Scenario: Level-shifting and overvoltage protection for 24 V digital inputs. IC Role / Device Role / Timing Role: Zener-based voltage limiter ensuring input stays within 27.5 V absolute maximum rating. Use Value: Prevents latch-up in input buffer ICs using only passive components - no active circuitry or layout area. | Use Scenario: Providing stable 25 V excitation for precision resistive bridge sensors. IC Role / Device Role / Timing Role: Low-drift voltage reference source for ratiometric measurement systems. Use Value: Delivers <0.55 V regulation error across 10–50 mA load range, enabling 0.1% measurement accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360B | ±5% tolerance (B suffix) vs. ±10% (A suffix); same VZ, IZT, ZZ, IZM, and package | Higher precision required where 25 V ±1.25 V is insufficient; tighter regulation improves feedback loop stability | Select 1N5360B when system-level voltage tolerance budget demands <±5% reference accuracy |
| MMBZ5252BS | Surface-mount SOD-123 package; 0.25 W rating; 25 V ±5%; 10 mA IZT; 35 Ω ZZ | Not suitable for 5 W power dissipation; limited to low-current bias/reference use in space-constrained PCBs | Choose MMBZ5252BS only for low-power signal-level referencing where board area is critical and power <0.3 W |
Compared with 1N5360B and MMBZ5252BS, the 1N5360AE3/TR8 uniquely supports high-power shunt regulation (5 W) with axial-leaded mounting flexibility and industrial-grade surge robustness - making it irreplaceable in mains-connected power supplies and ruggedized control hardware.

FAQ
What is the Zener voltage tolerance for 1N5360AE3/TR8?
The "A" suffix in 1N5360AE3/TR8 specifies a ±10% Zener voltage tolerance, meaning its regulated voltage falls between 22.5 V and 27.5 V at 50 mA test current and 25 °C. This tolerance directly impacts feedback accuracy in power supply designs and must be accounted for in worst-case analysis of output regulation.
Does 1N5360AE3/TR8 require dry packing for moisture sensitivity?
No, the 1N5360AE3/TR8 has IPC/JEDEC J-STD-020B moisture sensitivity level 1, confirmed by its plastic encapsulation and void-free epoxy body. It may be stored and assembled without dry pack or baking - simplifying inventory handling and reducing manufacturing cost.
What is the maximum continuous power dissipation for 1N5360AE3/TR8?
The 1N5360AE3/TR8 is rated for 5.0 W steady-state power dissipation at lead temperature (TL) < 25 °C with 3/8″ (10 mm) lead length from body. When mounted on FR4 with 1 oz copper, its derated power drops to 1.47 W at TA = 25 °C - requiring thermal design consideration for sustained operation.
How is polarity marked on 1N5360AE3/TR8?
The cathode of the 1N5360AE3/TR8 is marked by a single black band on the body; the diode must be reverse-biased with the banded end held positive relative to the unbanded (anode) end to achieve Zener conduction and voltage regulation.
What does the "TR8" suffix indicate in 1N5360AE3/TR8?
The "TR8" suffix denotes tape-and-reel packaging per EIA-296 standard, with 8 mm tape width and component orientation optimized for automated pick-and-place assembly. This format supports high-volume SMT production while preserving the device's RoHS-compliant matte-tin plating and JEDEC registration.
