Product details
Overview
1N5359BRLG from onsemi is a 5 W axial-lead Zener diode with nominal zener voltage of 24 V, ±5% tolerance, maximum zener impedance of 50 Ω at 3.5 mA test current, and surge rating of 198 A at 8.3 ms. It operates as a precision voltage reference or shunt regulator in DC power supply feedback paths and overvoltage protection circuits.
For engineers reviewing the 1N5359BRLG datasheet, pinout, applications, or equivalent options, key selection criteria include its 24 V regulation point, low 0.55 mA leakage at 18.2 V, 50 Ω dynamic impedance, Pb-free Surmetic 40 package, and compatibility with standard through-hole PCB layouts.
Technical Context
This device uses silicon-oxide passivated junction technology to achieve tight voltage tolerance and stable regulation under varying load and temperature conditions. Its thermal resistance from junction-to-lead is 25 °C/W at 3/8″ lead length, enabling reliable 5 W dissipation when properly heatsunk.
The 1N5359BRLG exhibits a positive temperature coefficient above 5 V, with typical TC of +0.075 mV/°C per volt - resulting in ~+1.8 mV/°C at 24 V - supporting predictable drift compensation in reference designs. It meets Class 3 ESD immunity (>16 kV HBM) and withstands non-repetitive 8.3 ms surges up to 198 A.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N5359B | Same electrical specs but SnPb lead finish; not RoHS-compliant | Acceptable only in legacy non-RoHS production | Select 1N5359BRLG for new designs requiring Pb-free compliance and modern assembly processes |
| MMSZ5245B | Surface-mount SOD-123 package; 24 V ±5%; 500 mW rating; 30 Ω ZZT | Used where board space is constrained and thermal mass is limited | Choose MMSZ5245B only for low-power (<500 mW), space-constrained applications; not a drop-in replacement |
Compared with 1N5359B (SnPb) and MMSZ5245B (SMT, 500 mW), the 1N5359BRLG offers full 5 W dissipation in a robust axial package with guaranteed RoHS compliance and superior surge handling - making it the preferred choice for industrial 24 V power regulation and protection where reliability and thermal margin are critical.

FAQ
What is the nominal zener voltage and tolerance of the 1N5359BRLG?
The 1N5359BRLG has a nominal zener voltage of 24 V with a guaranteed tolerance of ±5%, meaning its actual VZ falls between 22.8 V and 25.2 V at IZT = 3.5 mA. This tight tolerance is specified per JEDEC standards and confirmed in onsemi's Rev. 19 datasheet. The 1N5359BRLG achieves this using oxide-passivated silicon junctions, ensuring consistent performance across production lots and temperature ranges.
Can the 1N5359BRLG be used in surface-mount designs?
No, the 1N5359BRLG is an axial-lead device in the Surmetic 40 (CASE 017AA) package and is designed exclusively for through-hole mounting. It cannot be directly substituted into SMT layouts. For surface-mount equivalents, consider the MMSZ5245B (SOD-123, 24 V, 500 mW), but note its lower power rating and different thermal behavior. The 1N5359BRLG requires 3/8″ lead length for rated 5 W dissipation.
What is the maximum surge current rating for the 1N5359BRLG and under what conditions?
The 1N5359BRLG is rated for a maximum non-repetitive surge current of 198 A at a pulse width of 8.3 ms, as specified in the onsemi datasheet Figure 5 and Table on page 3. This rating assumes TA = 25°C and proper lead-to-heatsink mounting. The 1N5359BRLG maintains structural integrity and electrical parameters after such events, making it suitable for industrial surge protection applications where IEC 61000-4-5 compliance is required.
How does the temperature coefficient affect the 1N5359BRLG's regulation accuracy?
The 1N5359BRLG exhibits a positive temperature coefficient of approximately +1.8 mV/°C near 24 V (derived from +0.075 mV/°C per volt, per Figure 3). This means its zener voltage increases by ~1.8 mV for each 1°C rise in junction temperature. In practice, this results in <±0.3% drift over −40°C to +125°C junction range - a key factor in high-accuracy reference designs. The 1N5359BRLG's predictable TC allows for effective compensation in precision circuits.
Is the 1N5359BRLG RoHS-compliant and what does the 'G' suffix indicate?
Yes, the 1N5359BRLG is RoHS-compliant. The 'G' suffix explicitly denotes a Pb-free package per onsemi's packaging nomenclature (confirmed in datasheet footnotes and ordering information). This includes lead finishes and mold compound meeting EU Directive 2011/65/EU requirements. The 1N5359BRLG supports lead-free reflow soldering at 260°C for 10 seconds, aligning with IPC-J-STD-020 standards for moisture sensitivity level 1.
