Datasheet − production data
Description
A
The SM30TY Transil series has been designed to
protect automotive sensitive circuits against
surges defined in ISO 7637-2 and against
electrostatic discharges according to ISO 10605.
K
Unidirectional
Bidirectional
SMC
(JEDEC DO-214AB)
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. SM30TY are
packaged in SMC (SMC footprint in accordance
with IPC 7531 standard).
Features

• Unidirectional and bidirectional types
• Operating Tj max: 175 °C
• JEDEC registered package outline
• Resin meets UL 94, V0
• AEC-Q101 qualified
Complies with the following standards
• ISO 10605 - C = 150 pF, R = 330 Ω exceeds
level 4
– 30 kV (air discharge)
– 30 kV (contact discharge)
• ISO 10605 - C = 330 pF, R = 330 Ω exceeds
level 4
– 30 kV (air discharge)
– 30 kV (contact discharge)
• ISO 7637-2:
– Pulse 1: Vs = -150 V

1. Pulse test: tp < 50 ms
2. To calculate VBR or VCL versus junction temperature, use the following formulas:
VBR at TJ = VBR at 25 °C x (1 + αT x (TJ - 25))
VCL at TJ = VCL at 25 °C x (1 + αT x (TJ - 25))
3. 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.
4. Surge capability given for both directions for unidirectional and bidirectional types.
