PolySwitch^®Resettable PPTC Datasheet

Automotive ASMDC Series

Surface Mount

RoHS

Description

The ASMDC PPTC offers a lower profile form factor for better

space saving and provides higher VDC and IHOLD

rating, most robust performance compared to the competitors in

the market.

Features & Benefits

■ Products meet applicable

automotive industry

standards

■ Provides wider range of form

factors to enhance design

ﬂexibility

■ Compatible with high-volume

electronics assembly

■ Restores system operation

after reset when fault

condition is removed,

thus provides safety and

protection

■ Lower Proﬁle – Comparing to

the existing 2920 size ASMD

series

■ Able to meet most stringent

requirements for the

extreme harsh automotive

environment

■ Resettable solution against

overcurrent and short-circuit

Additional Information

■ AEC-Q200 qualiﬁed, RoHS

compliant, and

ISO/TS16949 certiﬁed

■ Suitable for standard

PCB assembly to enable

automated mass production

■ Surface-mount form factor

■ High Performance expertise

from the world’s leading

resettable overcurrent

: Hold current: maximum current device will pass without interruption in 25°C, unless otherwise specified

: Trip current: minimum current that will switch the device from low-resistance to high-resistance in 25°C still air, unless otherwise specified.

V_MAX: Maximum voltage device can withstand without damage at rated current.

I_MAX: Maximum fault current device can withstand without damage at rated voltage.

P_D: Power dissipated from device when in the tripped state in 25°C still air, unless otherwise specified.

R_MIN: Minimum resistance of device as supplied at 25°C, unless otherwise specified.

R_1MAX: Maximum resistance of device when measured one hour post reflow, unless otherwise specified.

R_aMAX: Maximum functional resistance of device after being subjected to the stresses described in PS400 at 25°C, unless otherwise specified.

Speciﬁcations are subject to change without notice.
