Engineering Selection Recommendations

Primary Substitutes (Infineon SIPMOS® Series):

BSP135H6327XTSA1 and BSP135H6906XTSA1 are parametric equivalents of the BSP135 E6906, offering identical electrical specifications across all critical parameters. Both parts carry Active product status and ROHS3 compliance, providing long-term supply chain security. The primary distinction between these two Infineon alternatives is packaging configuration: BSP135H6327XTSA1 is supplied in Cut Tape and Digi-Reel format, while BSP135H6906XTSA1 is supplied in Tape & Reel format. Selection between these two should be based on procurement and assembly line requirements.

Alternative Substitute (IXYS CPC3960ZTR):

The CPC3960ZTR from IXYS Integrated Circuits Division provides functional substitution with the same 600V Vdss rating, 1.8W power dissipation, and depletion mode operation. This part exhibits slightly lower on-state resistance (44 Ohm @ 100mA, 0V) and reduced input capacitance (100pF @ 25V) compared to the BSP135 series. The CPC3960ZTR operates within a reduced temperature range (-55°C to 125°C) relative to the BSP135 E6906 (-55°C to 150°C). This part carries ROHS3 compliance and Active product status.

Compliance Considerations:

All substitute parts listed carry ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements. The original BSP135 E6906 is RoHS non-compliant; substitution with any listed alternative improves regulatory alignment for new designs or production transitions.

Frequently Asked Questions (FAQ)

Q: Can BSP135H6327XTSA1 and BSP135H6906XTSA1 be used interchangeably with the BSP135 E6906?

A: Yes. Both parts are parametric equivalents with identical electrical specifications. The difference lies in packaging configuration: BSP135H6327XTSA1 is supplied in Cut Tape and Digi-Reel format, while BSP135H6906XTSA1 is supplied in Tape & Reel format. Selection depends on assembly line compatibility and procurement requirements.

Q: What are the key differences between the Infineon BSP135 variants and the IXYS CPC3960ZTR?

A: The CPC3960ZTR maintains electrical equivalence in Vdss (600V), power dissipation (1.8W), and package type (SOT-223). However, it exhibits lower input capacitance (100pF vs. 146pF) and operates within a reduced temperature range (-55°C to 125°C vs. -55°C to 150°C). On-state resistance specifications are measured at different conditions (44 Ohm @ 100mA, 0V vs. 45 Ohm @ 120mA, 10V), making direct comparison dependent on application operating point.

Q: Is the CPC3960ZTR suitable for applications requiring the full -55°C to 150°C temperature range?

A: No. The CPC3960ZTR is rated only to 125°C maximum junction temperature. Applications requiring operation above 125°C must use BSP135H6327XTSA1 or BSP135H6906XTSA1, which are rated to 150°C.

Q: Are all substitute parts RoHS compliant?

A: Yes. BSP135H6327XTSA1, BSP135H6906XTSA1, and CPC3960ZTR all carry ROHS3 compliance. The original BSP135 E6906 is RoHS non-compliant. Substitution with any listed alternative improves regulatory alignment.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) and Digi-Reel® packaging, as supplied with BSP135H6327XTSA1, is suitable for manual assembly and lower-volume production. Tape & Reel (TR) packaging, as supplied with BSP135H6906XTSA1 and CPC3960ZTR, is optimized for automated pick-and-place assembly systems. Selection depends on production methodology and assembly equipment compatibility.

Q: Can the BSP135 E6906 be directly replaced on existing PCBs without design modification?

A: Yes, for BSP135H6327XTSA1 and BSP135H6906XTSA1. Both maintain identical package type (PG-SOT223-4) and electrical specifications. The CPC3960ZTR uses SOT-223 packaging, which is mechanically compatible with TO-261-4 and TO-261AA footprints but should be verified against specific PCB layout requirements.

Q: What inventory levels are available for each substitute part?

A: BSP135H6906XTSA1 has the highest availability at 15,742 pieces. BSP135H6327XTSA1 has 4,460 pieces available. CPC3960ZTR has 2,200 pieces available. The original BSP135 E6906 has 889 pieces remaining in stock.
