Description
The SM15TY Transil series has been designed to
protect sensitive automotive circuits against
surges defined in ISO 7637-2 and against
electrostatic discharges according to ISO 10605.
a. Not applicable to parts with stand-off voltage lower
than the average battery voltage (13.5 V)
March 2012
This is information on a product in full production.
Bidirectional
SMC
(JEDEC DO-214AB)
Complies with the following standards
■
K
The Planar technology makes it compatible with
high-end circuits where low leakage current and
high junction temperature are required to provide
reliability and stability over time. SM15TY are
packaged in SMC (SMC footprint in accordance
with IPC 7531 standard).

1. Pulse test: tp < 50 ms
2. To calculate maximum clamping voltage at other surge level, use the following formula: VCLmax = VCL - RD x (IPP - IPPappli)
where IPPappli is the surge current in the application
3. To calculate VBR or VCL versus junction temperature, use the following formulas:
VBR @ TJ = VBR @ 25 °C x (1 + αT x (TJ - 25))
VCL @ TJ = VCL @ 25 °C x (1 + αT x (TJ - 25))
4. Surge capability given for both directions for unidirectional and bidirectional types.
