STIEC45-xxAS, STIEC45-xxACS

Transil™ TVS for IEC 61000-4-5 compliance

Datasheet - production data



MIL STD 883G, method 3015-7 Class 3B

25 kV HBM (human body model)





Resin meets UL 94, V0

MIL-STD-750, method 2026 solderability

EIA-481 and IEC 60286-3 packing

IPC 7531 footprint

Description

The STIEC45 Transil series has been designed

to protect DC power supply lines according to

IEC 61000-4-5. This device protects circuits

against electrical fast transients (EFT) according

to IEC 61000-4-4 and ETS EN 300 386.

Protection against electrostatic discharges is

provided according to IEC 61000-4-2 and MIL

STD 883 Method 3015.

Features



Peak pulse current: 500 A (1.2/50 μs,

8/20 μs)



Stand-off voltage range: from 24 V to 33 V

Unidirectional types: STIEC45-xxAS

Planar technology makes these devices suitable

for high-end equipment and SMPS where low

leakage current and high junction temperature

are required to provide reliability and stability

over time.



Reverse: Clamping starts at V_BR

Forward: Clamping starts around 0.6 V



Bidirectional types: STIEC45-xxACS



Clamping starts at V_BRon both

directions

The STIEC45 device is packaged in SMC (SMC

footprint in accordance with IPC 7351 standard).

Low leakage current

Transil is a trademark of STMicroelectronics
