The crash power module must guarantee that airbags and pretensioners have the electrical energy they need to fire, even in the instant the vehicle's main battery connection is lost during a severe collision. It requires dependable energy storage, rapid, controlled switching, and robust components that can support safety-critical pyrotechnic functions.

Vishay's capacitors — including tantalum and aluminum electrolytic types — store the reserve energy this backup power module supplies, while power MOSFETs and diodes manage the charging and discharging of that reserve safely. Our massive electro-pyrotechnic initiator resistors and high current MOSFETs ensure safety features, such as airbags, are reliably triggered, and our precision resistors monitor stored voltage to confirm the module is always ready.

Behind the crash power module is The DNA of tech.®
