Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Voltage - Reverse Standoff (Typ): 8V
Voltage - Clamping (Max) @ Ipp: 13.6V
Current - Peak Pulse (10/1000µs): 220.6A
Power - Peak Pulse: 3000W (3kW)

Parts are classified into two categories:

Direct Equivalents maintain all critical electrical parameters (8V standoff, 13.6V clamping, 220.6A peak pulse, 3000W power rating) with active product status and identical packaging.

Similar Alternatives share the same voltage rating and package but differ in peak pulse current or power dissipation capacity, suitable for applications with reduced transient energy requirements.

Engineering Selection Recommendations

Direct Equivalents (Full Specification Match)

SMLJ8.0A, SMDJ8.0A-HR, SMDJ8.0A-HRAT7, SMDJ8.0A, and SMDJ8.0A-HRA are direct functional equivalents with identical electrical specifications (8V standoff, 13.6V clamping, 220.6A peak pulse, 3000W power). All are active products with ROHS3 compliance. Selection among these should be based on packaging availability (Tape & Reel vs. Bulk) and extended temperature range requirements. Littelfuse variants (SMDJ8.0A-HR, SMDJ8.0A-HRAT7, SMDJ8.0A-HRA) support -65°C minimum operating temperature, compared to -55°C for Bourns and Alpha & Omega variants.

Similar Alternatives (Reduced Power Capacity)

SMCJ8.0A (Taiwan Semiconductor Corporation), SMCJ8.0A-TP (Micro Commercial Co), and SMCJ8V0A (Fairchild Semiconductor) maintain voltage specifications but operate at 115A to 110.3A peak pulse current and 1500W power dissipation. These are suitable for applications with lower transient energy requirements. SMCJ8.0A-TP extends operating temperature to -55°C ~ 175°C.

Marginal Alternative

SMCJ8.5A-13-F (Diodes Incorporated) deviates from the primary voltage specification with 8.5V standoff and 14.4V clamping voltage. This part is suitable only when the application circuit tolerates higher clamping voltage and reduced peak pulse current (104.2A).

Frequently Asked Questions (FAQ)

Q: Can SMLJ8.0A directly replace CD214L-T8.0ALF?

A: Yes. SMLJ8.0A is a direct equivalent with identical electrical specifications (8V standoff, 13.6V clamping, 220.6A peak pulse, 3000W power) and DO-214AB SMC packaging. Both are Bourns products with ROHS3 compliance. The primary difference is product status: SMLJ8.0A is active while CD214L-T8.0ALF is obsolete.

Q: What is the difference between SMDJ8.0A-HR and SMDJ8.0A-HRAT7?

A: Both are Littelfuse products with identical electrical specifications and operating temperature range (-65°C ~ 150°C). The suffix designations indicate different manufacturing or packaging variants. Electrical performance is equivalent for circuit design purposes.

Q: Can I use SMCJ8.0A as a substitute if peak pulse current is lower?

A: SMCJ8.0A operates at 115A peak pulse versus 220.6A for the original part, with 1500W power dissipation versus 3000W. This substitution is valid only if the application circuit generates transient pulses within the reduced current and power specifications. Voltage ratings (8V standoff, 13.6V clamping) remain identical.

Q: Why does SMCJ8.5A-13-F have different voltage ratings?

A: SMCJ8.5A-13-F has 8.5V standoff and 14.4V clamping voltage, deviating from the 8V/13.6V specification. This part is suitable only for circuits that tolerate higher clamping voltage and can operate with reduced peak pulse current (104.2A).

Q: What packaging options are available?

A: All parts use DO-214AB SMC surface mount package. Packaging format varies: SMLJ8.0A, SMDJ8.0A variants, SMCJ8.0A-TP, and SMDJ8.0A are available in Tape & Reel format. SMCJ8.0A is available in Bulk. SMCJ8V0A packaging is not specified in available data.

Q: Are all substitutes ROHS3 compliant?

A: All direct equivalents and similar alternatives listed are ROHS3 compliant. REACH status varies: Bourns and Littelfuse parts are REACH Affected or Unaffected as specified. All parts carry EAR99 ECCN classification.
