Substitute Part Grouping Explanation

Substitute parts for the TV30C151J-G are classified into two functional groups based on electrical performance and application suitability:

Group 1: Higher Current Rating Substitutes These parts maintain identical voltage specifications (150V standoff, 243V clamping) while providing increased peak pulse current capacity and power dissipation. Substitution is valid when circuit design permits higher current handling without adverse effects.

• 5.0SMDJ150A (MDE Semiconductor Inc): 20.6A Ipp, 5000W peak pulse
• 5.0SMDJ150A-T7 (Littelfuse): 20.6A Ipp, 5000W peak pulse

Group 2: Standard Current Rating Substitutes These parts match the voltage specifications and provide comparable or equivalent peak pulse current ratings within the 6.2A to 12.4A range, suitable for direct replacement in existing designs.

• SMCJ150A (Fairchild Semiconductor): 6.2A Ipp, 1500W peak pulse
• SMCJ150A-13-F (Diodes Incorporated): 6.2A Ipp, 1500W peak pulse
• SMCJ150A-TP (Micro Commercial Co): 6.2A Ipp, 1500W peak pulse
• SMDJ150A (Alpha & Omega Semiconductor Inc.): 12.4A Ipp, 3000W peak pulse

All substitute parts share the following critical parameters with the main part:

• Voltage - Reverse Standoff: 150V
• Voltage - Breakdown (Min): 167V
• Voltage - Clamping (Max) @ Ipp: 243V
• Package: DO-214AB, SMC (surface mount)
• Type: Zener, Unidirectional
• Applications: General Purpose

Parameter Comparison

Engineering Selection Recommendations

Selection of substitute parts must be based on circuit requirements and compliance status:

For Direct Replacement (Equivalent Performance) SMDJ150A from Alpha & Omega Semiconductor Inc. provides the closest electrical match to TV30C151J-G, with identical peak pulse current (12.4A vs 12.35A) and power dissipation (3000W). Both parts carry ROHS3 compliance and operate within the same temperature range (-55°C ~ 150°C). This part is suitable for one-to-one substitution in existing designs without circuit modification.

For Enhanced Current Capacity 5.0SMDJ150A and 5.0SMDJ150A-T7 are suitable when circuit design permits higher current handling (20.6A vs 12.35A) and increased power dissipation (5000W vs 3000W). Both maintain identical voltage specifications and ROHS3 compliance. The Littelfuse variant (5.0SMDJ150A-T7) extends the lower operating temperature limit to -65°C, providing wider thermal range coverage.

For Cost-Optimized Selection SMCJ150A variants (Fairchild Semiconductor, Diodes Incorporated, Micro Commercial Co) operate at reduced current ratings (6.2A) and power dissipation (1500W). These parts are suitable only when circuit design accommodates lower current capacity. SMCJ150A-TP from Micro Commercial Co extends the upper operating temperature to 175°C, supporting high-temperature applications.

All substitute parts maintain the DO-214AB (SMC) package format, ensuring mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can SMCJ150A replace TV30C151J-G directly? A: SMCJ150A shares identical voltage specifications (150V standoff, 243V clamping) and package format (DO-214AB, SMC) but operates at reduced peak pulse current (6.2A vs 12.35A) and power dissipation (1500W vs 3000W). Direct replacement is valid only if the circuit design accommodates the lower current rating without exceeding component thermal limits.

Q: What is the difference between 5.0SMDJ150A and 5.0SMDJ150A-T7? A: Both parts are electrically identical with 20.6A peak pulse current and 5000W power dissipation. The primary difference is operating temperature range: 5.0SMDJ150A operates -55°C ~ 150°C, while 5.0SMDJ150A-T7 extends to -65°C ~ 150°C. Selection depends on application thermal requirements.

Q: Are all substitute parts ROHS3 compliant? A: ROHS3 compliance is confirmed for TV30C151J-G, 5.0SMDJ150A, 5.0SMDJ150A-T7, SMCJ150A-13-F, SMCJ150A-TP, and SMDJ150A. Fairchild Semiconductor's SMCJ150A does not specify RoHS status in the provided data.

Q: Can I use a higher current-rated part in place of TV30C151J-G? A: Yes. 5.0SMDJ150A and 5.0SMDJ150A-T7 provide higher current capacity (20.6A) while maintaining identical voltage specifications. This substitution is valid when circuit design permits increased current handling without adverse effects on component selection or thermal management.

Q: What packaging formats are available for these substitute parts? A: All parts use DO-214AB (SMC) surface-mount package. Packaging options vary by manufacturer: Tape & Reel (TR), Bulk, or Cut Tape (CT) & Digi-Reel®. Verify packaging format with supplier based on assembly process requirements.

Q: Is SMDJ150A a suitable one-to-one replacement? A: Yes. SMDJ150A from Alpha & Omega Semiconductor Inc. provides equivalent electrical performance with 12.4A peak pulse current and 3000W power dissipation, matching the original part's specifications. Both maintain ROHS3 compliance and identical operating temperature range (-55°C ~ 150°C).
