Engineering Selection Recommendations

Parametric Equivalent Selection (Direct Replacement):

For applications requiring full electrical and mechanical equivalence to the ES2JAHR3G, select from the parametric equivalent group:

ES2JAH is the preferred choice. This part maintains identical electrical specifications (600 V, 2 A, 35 ns recovery time) and carries automotive-grade qualification with AEC-Q101 certification, matching the original part's qualification status. Product status is Active, ensuring long-term availability.
ES2JA provides parametric equivalence with identical electrical performance. Product status is Active with higher inventory availability (34,435 units). This part lacks explicit automotive grading but maintains all electrical parameters.
ES2JA R3G offers parametric equivalence but carries Discontinued status at DiGi Electronics, limiting its suitability for new designs despite adequate inventory (10,051 units).

Similar Part Selection (Current-Derated Applications):

For applications where the 2 A current requirement can be reduced to 1 A, similar parts provide alternative sourcing:

CMR1F-06M TR13 PBFREE (Central Semiconductor Corp) offers fast recovery characteristics (250 ns trr) with the highest inventory (9,694 units) and Active status. Operating temperature range extends to 175°C maximum junction temperature.
CMR1F-06M BK PBFREE provides identical electrical performance in bulk packaging with 922 units available.
CFRA105-G and CGRA4005-G (Comchip Technology) deliver fast recovery performance with Active status but lower inventory levels.
CMR1-06M variants (Central Semiconductor Corp) feature standard recovery characteristics (>500 ns) with extended temperature range (-65°C to 150°C).

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and DO-214AC package compatibility.

Frequently Asked Questions (FAQ)

Q: Can ES2JA directly replace ES2JAHR3G in automotive applications?

A: ES2JA provides full parametric equivalence (600 V, 2 A, 35 ns recovery) but lacks explicit automotive grading. ES2JAH is the recommended replacement for automotive applications, as it carries AEC-Q101 qualification matching the original part's grade specification.

Q: What is the difference between parametric equivalent and similar parts?

A: Parametric equivalent parts (ES2JA, ES2JAH, ES2JA R3G) maintain identical electrical ratings across voltage, current, and recovery characteristics. Similar parts (CFRA105-G, CGRA4005-G, CMR1 series) share the same voltage rating and package but operate at reduced current (1 A vs. 2 A). Similar parts are suitable only for applications where lower current capacity is acceptable.

Q: Are the 1 A rated diodes suitable as drop-in replacements?

A: No. The 1 A rated parts (CMR1-06M, CMR1F-06M, CMR1U-06M, CFRA105-G, CGRA4005-G) cannot function as drop-in replacements in circuits designed for 2 A operation. These parts are suitable only for redesigned circuits with reduced current requirements or for applications where the 2 A rating provides design margin.

Q: What packaging options are available for equivalent parts?

A: ES2JA and ES2JAH are supplied in Tape & Reel (TR) packaging. The original ES2JAHR3G does not specify packaging format. All equivalent and similar parts use the DO-214AC (SMA) surface mount package, ensuring mechanical compatibility.

Q: How do recovery time specifications affect substitution?

A: The ES2JAHR3G specifies 35 ns reverse recovery time (trr). Parametric equivalents (ES2JA, ES2JAH, ES2JA R3G) maintain this specification. Similar parts vary: CMR1F-06M and CFRA105-G specify 250 ns, while CMR1U-06M specifies 75 ns. Faster recovery reduces switching losses but may not be required in all applications. Slower recovery times may introduce additional switching losses in high-frequency circuits.

Q: What is the significance of automotive grading and AEC-Q101 qualification?

A: Automotive grading and AEC-Q101 qualification indicate the part meets automotive industry reliability and qualification standards. ES2JAHR3G and ES2JAH carry this designation. For non-automotive applications, parts without automotive grading (ES2JA, Comchip, and Central Semiconductor parts) are functionally equivalent. For automotive applications, ES2JAH is the recommended equivalent.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All parts listed in this reference maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), supporting deployment in standard manufacturing environments without special handling requirements.

Q: What inventory considerations apply to part selection?

A: ES2JAH (15,753 units) and ES2JA (34,435 units) offer substantial inventory for immediate procurement. ES2JAHR3G (909 units) and ES2JA R3G (10,051 units) are discontinued or limited. CMR1F-06M TR13 PBFREE (9,694 units) provides the highest inventory among 1 A alternatives. Inventory levels should be verified with suppliers for current availability.
