The P4SMAJ series is a surface mount transient voltage suppressor with features including 400W peak pulse power dissipation, 5.0V-170V standoff voltage, availability in uni- and bi-directional versions, excellent clamping capability, and fast response time.
The P4SMAJ series from WTE offers 400 W peak pulse power dissipation transient voltage suppressors in both unidirectional and bi‑directional versions. Features include glass‑passivated die construction, fast response time, and UL‑rated plastic case material.
Mechanical data specify a JEDEC DO‑214AC low‑profile molded plastic package with dimensions from 0.050 in to 0.083 in and a weight of about 0.064 g. Maximum ratings cover a standoff voltage range of 5.0 V‑170 V and an operating temperature range of –55 °C to +150 °C. The handbook also lists detailed electrical characteristics, peak‑pulse derating curves, ordering part numbers, and recommended footprints.
