Product details
Overview
SMAJ60CAHE3_A/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMA (DO-214AC) package, designed for clamping voltage transients on power and signal lines. It features 60 V standoff voltage (VWM), 66.7–73.7 V breakdown voltage (VBR) at 1 mA, 96.8 V maximum clamping voltage (VC) at 4.1 A peak pulse current (IPPM), and 400 W peak pulse power (10/1000 μs waveform), suitable for protecting MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the SMAJ60CAHE3_A/H datasheet, SMAJ60CAHE3_A/H pinout, SMAJ60CAHE3_A/H application, or SMAJ60CAHE3_A/H equivalent, key selection criteria include bidirectional surge suppression capability, AEC-Q101 qualification, 150 °C junction temperature rating, low incremental surge resistance, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This device operates as a voltage-clamping protector with symmetrical reverse/forward conduction behavior due to its bidirectional construction. It responds within picoseconds to transient overvoltages induced by inductive switching or ESD events, limiting voltage across protected circuitry to ≤96.8 V at 4.1 A IPPM while dissipating up to 400 W peak pulse power.
Thermal performance is defined by 120 °C/W junction-to-ambient thermal resistance (RθJA) and 30 °C/W junction-to-lead (RθJL), enabling reliable operation up to +150 °C junction temperature. Its glass-passivated junction and matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA-M3 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification. | No difference in functional use; selected when halogen-free material compliance is required for end-product certification. | Choose SMAJ60CA-M3 if halogen-free bill-of-materials is mandated by regional environmental regulations. |

FAQ
What is the clamping voltage of SMAJ60CAHE3_A/H at its rated peak pulse current?
The SMAJ60CAHE3_A/H has a maximum clamping voltage (VC) of 96.8 V at its rated peak pulse current (IPPM) of 4.1 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and ensures downstream components see no more than 96.8 V during surge events, critical for safeguarding 5 V or 3.3 V logic circuits in automotive applications where SMAJ60CAHE3_A/H is commonly deployed.
Is SMAJ60CAHE3_A/H suitable for automotive applications?
Yes, SMAJ60CAHE3_A/H is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix "HE3". It meets rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD, making it appropriate for engine control units, body electronics, and ADAS modules. The SMAJ60CAHE3_A/H datasheet confirms qualification status and lists automotive-grade packaging and marking requirements.
What does the "CA" suffix indicate in SMAJ60CAHE3_A/H?
The "CA" suffix in SMAJ60CAHE3_A/H denotes a bidirectional configuration, meaning the device provides symmetrical transient suppression in both polarities-ideal for AC signal lines, differential buses, or ungrounded circuits. Unlike unidirectional "A" variants, SMAJ60CAHE3_A/H has no cathode marking and conducts identically in forward and reverse bias above VBR, simplifying layout and eliminating polarity orientation errors during assembly.
How does the thermal performance of SMAJ60CAHE3_A/H affect PCB layout?
SMAJ60CAHE3_A/H exhibits a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on minimum recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. To maintain TJ ≤ 150 °C under repetitive surge conditions, designers must allocate adequate copper area and avoid thermal bottlenecks. The SMAJ60CAHE3_A/H package (SMA/DO-214AC) relies on these pads for heat dissipation-reducing pad size degrades RθJA and risks thermal runaway during sustained transient activity.
What is the maximum reverse leakage current for SMAJ60CAHE3_A/H at its standoff voltage?
The SMAJ60CAHE3_A/H has a maximum reverse leakage current (ID) of 1.0 μA at its 60 V standoff voltage (VWM), measured at TA = 25 °C. This low leakage ensures minimal power loss in always-on circuits such as automotive wake-up receivers or battery-backed sensor interfaces, preserving system efficiency without compromising protection readiness. The specification is verified per the official Vishay datasheet revision dated 09-Jan-2024 for SMAJ60CAHE3_A/H.
