Customer Need |
How 2CL7-SH Solves It |
|
Need smaller HV diode for compact design |
φ2.5mm × 6.5mm body (2CL71ASH) is among the smallest for 8KV – saves PCB real estate. |
|
Need fast recovery to reduce heat |
100ns trr lowers switching losses, reduces heat sink requirements. |
|
Need reliable surge handling |
0.5A IFSM handles repetitive spark discharges without failure. |
|
Need low leakage for battery operation |
≈3µA reverse current extends standby and operating life. |
|
Need drop-in replacement for obsolete parts |
Directly replaces legacy 2CL71 / 2CL73 and similar models – no design change. |
|
Need high voltage in small package |
12KV rating in a 10mm × 2.5mm body – excellent voltage density. |
|
Need wide temperature operation |
Tj = 120°C allows use in enclosed or warm environments. |
|
Need RoHS compliance for global sales |
RoHS compliant – suitable for EU and North American markets. |
