Product details
Overview
1N5360B from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 25 V, ±5% tolerance, 50 Ω maximum zener impedance at 4 mA test current, and 190 A peak surge current rating for 8.3 ms pulses. It operates as a precision voltage reference or shunt regulator in DC power supply feedback paths, overvoltage protection circuits, and voltage-clamping applications.
For engineers reviewing the 1N5360B datasheet, pinout, applications, or equivalent options, key selection criteria include its 25 V nominal regulation voltage, 110 A maximum DC zener current, 0.55 mA leakage current at 19 V, and compatibility with standard through-hole PCB assembly using its CASE 017AA package.
Technical Context
The 1N5360B employs a silicon-oxide passivated junction to achieve tight voltage tolerance (±5%), low dynamic impedance, and high ESD robustness (Class 3, >16 kV HBM). Its thermal design relies on lead-to-ambient conduction, with junction-to-lead thermal resistance of 25 °C/W at 3/8″ lead length.
It delivers stable regulation across −65 °C to +200 °C operating range, with temperature coefficient of +11.5 mV/°C (typical) for 25 V units. Surge capability is defined per non-repetitive 8.3 ms square-wave pulses up to 190 A, validated under JEDEC test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 23.75–26.25 V at IZT = 4 mA - defines precise regulation point for feedback or clamping |
| Power Dissipation | 5 W at TL = 25 °C - sets maximum continuous DC power handling in lead-mounted configuration |
| Zener Impedance | 50 Ω max at IZT = 4 mA - ensures minimal output voltage variation under load transients |
| Leakage Current | 0.55 mA max at VR = 19 V - guarantees low standby power loss in high-impedance bias networks |
| Surge Current | 190 A peak for 8.3 ms - enables transient overvoltage suppression without failure |
| Max DC Zener Current | 110 A - derived from PD/VZ(min), limiting safe continuous conduction |
| ESD Rating | Class 3 (>16 kV HBM) - supports robust handling in automated assembly and field environments |
Pinout & Package

| Cathode | Zener breakdown terminal / voltage reference output | Provides stable 25 V reference when reverse-biased above VZ; marked with band |
Key Features
| Feature | Design Value |
|---|---|
| ±5% Zener voltage tolerance | Guarantees tight regulation window (23.75–26.25 V) without post-manufacturing trimming |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5360BRLG | Same electrical specs; tape-and-reel packaging (4000 pcs/reel) vs. bulk box (1000 pcs) | Optimized for automated SMT placement with orientation marking; identical thermal and electrical behavior | Select for high-volume production requiring pick-and-place compatibility |
| BZX85C24 | 24 V nominal, ±5%, 1.3 W power rating, TO-204AA metal can package | Lower power handling and different thermal path; requires heatsinking above 0.5 W | Choose only for legacy designs where 24 V tolerance is acceptable and metal-can mounting is required |
Compared with 1N5360B, the 1N5360BRLG offers identical regulation performance in automated assembly format, while BZX85C24 provides a lower-power, metal-can alternative with distinct thermal management needs and reduced surge capability.

FAQ
What is the nominal zener voltage and tolerance of the 1N5360B?
The 1N5360B has a nominal zener voltage of 25 V with a guaranteed tolerance of ±5%, corresponding to a minimum of 23.75 V and maximum of 26.25 V at 4 mA test current. This tolerance is specified per JEDEC standards and applies strictly to the B-suffix device variant documented in the onsemi datasheet Rev. 19.
What is the maximum steady-state power dissipation for the 1N5360B?
The 1N5360B is rated for 5 W maximum steady-state power dissipation at lead temperature (TL) of 25 °C with 3/8 inch lead length. Derating is required above 25 °C at 40 mW/°C, meaning usable power drops to 4 W at 50 °C lead temperature. This rating assumes proper lead-to-heatsink thermal conduction.
How does the 1N5360B perform under surge conditions?
The 1N5360B supports a peak non-repetitive surge current of 190 A for an 8.3 ms square-wave pulse, as verified per JEDEC test method. This capability enables reliable operation in IEC 61000-4-5 compliant surge protection circuits without parameter shift or catastrophic failure when used within datasheet-defined mounting and thermal conditions.
What is the leakage current specification for the 1N5360B?
The 1N5360B specifies a maximum reverse leakage current (IR) of 0.55 mA at VR = 19 V, measured at 25 °C. This value reflects the diode's ability to minimize standby power loss in high-impedance bias networks and ensures predictable turn-on behavior in precision reference applications.
Is the 1N5360B RoHS-compliant and what package type does it use?
Yes, the 1N5360B is Pb-free and RoHS-compliant, indicated by the "G" suffix in ordering codes like 1N5360BG. It uses an axial-lead, transfer-molded plastic package designated CASE 017AA, with cathode polarity marked by a visible band and dimensions conforming to JEDEC outline standards.
