Key Parameters

Substitute Part Grouping Explanation

Substitution of Zener diodes within this category is determined by equivalence in the following parameters:

Critical Electrical Parameters:

• Voltage - Zener (Nominal): 36 V
• Power - Maximum: 250 mW
• Impedance (Maximum): 90 Ohms
• Operating Temperature: 150°C (TJ)

Critical Mechanical Parameters:

• Package / Case: TO-236-3, SC-59, SOT-23-3
• Mounting Type: Surface Mount

Compliance & Qualification:

• Grade: Automotive
• Qualification: AEC-Q101
• RoHS Status: ROHS3 Compliant

All four substitute parts (BZX84B36VLFHT116, BZX84B36VLT116, BZX84B36VLYFHT116, BZX84B36VLYT116) manufactured by Rohm Semiconductor maintain identical nominal Zener voltage, maximum power dissipation, impedance, and operating temperature specifications. All are surface mount devices in compatible TO-236-3/SOT-23-3 packages with automotive-grade qualification and AEC-Q101 certification. Tolerance specifications for substitute parts are ±1.94%, which is tighter than the main part's ±5% tolerance, providing enhanced voltage regulation precision.

Parameter Comparison

Engineering Selection Recommendations

All four Rohm Semiconductor substitute parts are functionally equivalent to the BZX84-C36-QR for applications requiring a 36 V, 250 mW Zener diode in a surface mount package.

BZX84B36VLFHT116 and BZX84B36VLYFHT116 are recommended for applications with strict automotive compliance requirements. Both parts carry AEC-Q101 qualification and automotive-grade designation, matching the primary part's certification status. BZX84B36VLFHT116 is supplied in Cut Tape & Digi-Reel® packaging, while BZX84B36VLYFHT116 is supplied in Tape & Reel format.

BZX84B36VLT116 and BZX84B36VLYT116 maintain identical electrical specifications and surface mount package compatibility. These parts do not carry explicit automotive-grade or AEC-Q101 designation in the provided data. BZX84B36VLT116 is supplied in Cut Tape & Digi-Reel® packaging, while BZX84B36VLYT116 is supplied in Tape & Reel format.

All substitute parts feature tighter tolerance specifications (±1.94%) compared to the main part (±5%), resulting in improved voltage regulation accuracy. All parts are RoHS3 compliant and REACH unaffected. Packaging format selection (Cut Tape vs. Tape & Reel) depends on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can BZX84B36VLFHT116 be used as a direct replacement for BZX84-C36-QR?

A: Yes. Both parts share identical nominal Zener voltage (36 V), maximum power dissipation (250 mW), impedance (90 Ohms), and operating temperature (150°C). Both are surface mount devices in TO-236-3/SOT-23-3 packages with automotive-grade qualification and AEC-Q101 certification. The primary difference is packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel) and tighter tolerance on the substitute part (±1.94% vs. ±5%).

Q: What is the difference between the four Rohm substitute parts?

A: The four Rohm parts differ in packaging format and automotive qualification status. BZX84B36VLFHT116 and BZX84B36VLYFHT116 carry explicit automotive-grade designation and AEC-Q101 qualification. BZX84B36VLT116 and BZX84B36VLYT116 do not carry these designations in the provided specifications. BZX84B36VLFHT116 and BZX84B36VLT116 are supplied in Cut Tape & Digi-Reel® format, while BZX84B36VLYFHT116 and BZX84B36VLYT116 are supplied in Tape & Reel format.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the same package designation (TO-236-3, SC-59, SOT-23-3) and are surface mount devices. PCB footprints are identical across all parts listed.

Q: Does the tighter tolerance of substitute parts affect circuit performance?

A: The substitute parts feature ±1.94% tolerance compared to the main part's ±5% tolerance. This tighter tolerance provides improved voltage regulation precision and reduced variation in Zener voltage across the specified operating range. Applications requiring precise voltage reference will benefit from this specification.

Q: Are all parts RoHS3 compliant?

A: Yes. All parts listed, including the main part and all four substitutes, are RoHS3 compliant and REACH unaffected.

Q: Which substitute part should be selected for automotive applications?

A: For automotive applications requiring explicit AEC-Q101 qualification and automotive-grade designation, select either BZX84B36VLFHT116 (Cut Tape & Digi-Reel® packaging) or BZX84B36VLYFHT116 (Tape & Reel packaging). Both parts maintain full automotive compliance equivalent to the primary part.
