1N5362BRL Equivalent & Substitute Parts

Part Overview

The 1N5362BRL is a Zener diode rated for 28 V nominal voltage and 5 W maximum power dissipation in a through-hole axial package (T-18). Manufactured by onsemi, this component is classified as obsolete. Due to its obsolete status, equivalent substitute parts are necessary for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage regulation, power handling, and thermal operating ranges while accommodating available packaging and compliance options.

Substitute Part Grouping Explanation

Substitution of the 1N5362BRL is determined by the following critical parameters:

Electrical Compatibility Requirements:

Zener voltage: 28 V nominal
Voltage tolerance: ±5% (allows tolerance variations within design margin)
Power rating: 5 W maximum (substitutes with lower power ratings are not equivalent)
Impedance: 6 Ohms maximum
Reverse leakage current: 500 nA @ 21.2 V
Forward voltage: 1.2 V @ 1 A

Mechanical Compatibility Requirements:

Mounting type: Through Hole
Package type: T-18 Axial

Thermal Requirements:

Operating temperature range: -65°C ~ 200°C

Substitute parts are grouped into two categories:

Direct Substitutes (Electrical & Mechanical Equivalence): Parts that maintain all electrical parameters (28 V, ±5%, 5 W, 6 Ohms impedance) and identical T-18 axial packaging. These parts differ only in packaging format (bulk, cut tape, or tape & reel) and compliance status.

Functional Alternatives (Reduced Power Rating): Parts with matching 28 V nominal voltage and ±5% tolerance but reduced power ratings (500 mW instead of 5 W). These are suitable only for applications where the lower power dissipation capacity is acceptable. These parts use DO-35 (DO-204AH) packaging instead of T-18.

Engineering Selection Recommendations

Primary Substitute (Direct Electrical & Mechanical Equivalent):

The 1N5362BRLG is the recommended direct substitute for the obsolete 1N5362BRL. Both parts maintain identical electrical specifications (28 V, ±5%, 5 W, 6 Ohms impedance) and T-18 axial packaging. The 1N5362BRLG is currently in active production status with ROHS3 compliance, addressing both obsolescence and regulatory requirements. This part is suitable for direct replacement in existing designs without circuit modification.

Alternative Substitutes (Same Power Rating, Tolerance Variation):

The 1N5362/TR12 and 1N5362/TR8 (Microchip Technology) provide equivalent 5 W power handling and T-18 packaging but with ±20% voltage tolerance compared to the ±5% specification of the original part. These are suitable for applications where the wider tolerance band is acceptable within circuit design margins.

The 1N5362A/TR12 and 1N5362A/TR8 (Microchip Technology) offer ±10% voltage tolerance with identical 5 W power rating and T-18 packaging, providing a middle-ground tolerance specification.

Functional Alternatives (Reduced Power Rating):

The 1N4119-1, 1N4712, and 1N5255B are 500 mW alternatives with 28 V nominal voltage and ±5% tolerance. These parts use DO-35 packaging instead of T-18 and are suitable only for applications where power dissipation does not exceed 500 mW. The 1N5255A provides ±10% tolerance at the same 500 mW power level.

Compliance Considerations:

All substitute parts listed are RoHS non-compliant except 1N5362BRLG (ROHS3 compliant). For applications requiring RoHS compliance, 1N5362BRLG is the only available option among the listed substitutes.

Frequently Asked Questions (FAQ)

Q: Can I use a 500 mW Zener diode (1N4119-1, 1N4712, 1N5255B) as a direct replacement for the 1N5362BRL?

A: No. The 1N5362BRL is rated for 5 W maximum power dissipation, while these alternatives are rated for 500 mW. Using a lower-power device in an application designed for 5 W operation will result in component failure due to thermal overload. These parts are suitable only for applications where power dissipation is confirmed to remain below 500 mW.

Q: What is the difference between 1N5362/TR12, 1N5362/TR8, 1N5362A/TR12, and 1N5362A/TR8?

A: All four parts maintain the same 28 V nominal voltage, 5 W power rating, and T-18 axial packaging. The differences are: (1) voltage tolerance: 1N5362 series has ±20% tolerance while 1N5362A series has ±10% tolerance; (2) packaging format: TR12 indicates tape & reel with 12 mm pitch, TR8 indicates tape & reel with 8 mm pitch. Select based on your tolerance requirements and tape reel specifications for automated assembly.

Q: Is 1N5362BRLG a direct replacement for 1N5362BRL?

A: Yes. The 1N5362BRLG is electrically and mechanically identical to 1N5362BRL, with identical 28 V nominal voltage, ±5% tolerance, 5 W power rating, and T-18 axial packaging. The primary differences are: (1) 1N5362BRLG is in active production while 1N5362BRL is obsolete; (2) 1N5362BRLG is ROHS3 compliant while 1N5362BRL is RoHS non-compliant; (3) 1N5362BRLG uses cut tape packaging while 1N5362BRL uses bulk packaging.

Q: Why do some substitutes have different impedance values?

A: Impedance (Zzt) is a parameter that varies by device design and power rating. The 1N5362BRL has 6 Ohms impedance at 5 W. Lower-power alternatives (500 mW devices) have higher impedance values (44 Ohms to 200 Ohms) due to their different internal construction. This difference affects circuit behavior at high currents and should be evaluated in your specific application.

Q: Can I use 1N5362/TR12 or 1N5362/TR8 if my design requires ±5% tolerance?

A: No. These parts have ±20% voltage tolerance, which exceeds the ±5% specification of the original 1N5362BRL. If your circuit design requires ±5% tolerance, use 1N5362BRLG (direct equivalent) or 1N5362A/TR12 and 1N5362A/TR8 (±10% tolerance, which is tighter than ±20% but not as tight as ±5%).

Q: What is the difference between bulk, cut tape, and tape & reel packaging?

A: These are packaging and delivery formats: (1) Bulk packaging is loose components in a container, suitable for manual assembly; (2) Cut tape (CT) is components cut from tape in specified quantities, suitable for semi-automated assembly; (3) Tape & reel (TR) is components on continuous tape wound on a reel, suitable for fully automated pick-and-place assembly. All three formats contain electrically identical components; selection depends on your assembly process.

Q: Are all substitute parts RoHS compliant?

A: No. Only 1N5362BRLG is ROHS3 compliant. All other listed substitutes are RoHS non-compliant. If your application or regulatory requirements mandate RoHS compliance, 1N5362BRLG is the only suitable option.

Q: What is the operating temperature range difference between 1N5362BRL and the 500 mW alternatives?

A: The 1N5362BRL operates from -65°C to 200°C. The 500 mW alternatives (1N4119-1, 1N4712, 1N5255B, 1N5255A) operate from -65°C to 175°C. If your application requires operation above 175°C, the 1N5362BRL or its direct equivalents (1N5362BRLG, 1N5362/TR12, 1N5362/TR8, 1N5362A/TR12, 1N5362A/TR8) must be used.
