SMAJ16CA Transient Voltage Suppression Diode DO-214AC
SMAJ16CA Transient Voltage Suppression Diode DO-214AC
I. Product Overview
SMAJ16CA is a bidirectional transient-voltage-suppression (TVS) diode in SMA (DO-214AC) surface-mount package, designed for transient over-voltage protection of 16 V DC systems. Adopting glass-passivated die construction with excellent clamping capability and fast response time, it can rapidly dissipate high-energy transient pulses such as ESD, EFT and induced surges, and protect 16 V circuits in industrial, automotive and power-supply equipment from damage caused by transient high-voltage shocks.
II. Product Characteristics
Package: SMA (DO-214AC), transfer molded epoxy surface-mount package Polarity: Bidirectional (no cathode band marking) VRWM (Reverse Working Voltage): 16.0 V VBR (Breakdown Voltage): 17.8 V (min) ~ 19.7 V (max) Test Current (IT): 1.0 mA VC (Maximum Clamping Voltage): 26.0 V IPP (Peak Pulse Current): 15.4 A IR (Reverse Leakage Current): 5 μA Peak Pulse Power Dissipation: 400 W (10/1000 μs waveform) Peak Forward Surge Current: 40 A (8.3 ms single half sine-wave, JEDEC Method) Terminals: Solder-plated, solderable per MIL-STD-750, Method 2026 Flame Retardant Rating: UL 94V-0 Operating & Storage Temperature: -55℃ ~ +150℃ Note: Power rating is measured on 5.0 mm² copper pad. Pulses are non-repetitive. Derating is required when ambient temperature exceeds 25℃. Maximum duty cycle: 4 pulses per minute.
III. Product Advantages
Pulse energy dissipation: 400 W peak pulse power to withstand transient high-voltage shocks from ESD and induced surges. Excellent clamping performance: Glass-passivated die quickly clamps transient high-voltage down to safe voltage level. Fast response: Fast response delivers outstanding suppression performance for high-speed transient interference. Forward surge withstand: Endures 40 A short-time forward surge current with strong anti-pulse disturbance capability. Ultra-low leakage current: Only 5 μA, low static power consumption and minimal disturbance to original system. High reliability: Glass-passivated chip features high temperature resistance and anti-aging property for stable long-term operation. SMT compatibility: SMA surface-mount package supports automatic SMT assembly and fits compact PCB layout.
IV. Application Fields
Industrial control: Protection for 16 V industrial control modules, PLC, sensors and signal ports Automotive electronics: Port protection for 12-16 V vehicle electrical systems and on-board control units Power management: Input & output protection for industrial adapters and DC-DC modules Communication equipment: Power and signal port protection for industrial switches and network devices Instruments & meters: Transient over-voltage protection for internal circuits of test instruments
