Product details
Overview
SMAJ130CAHE3/61 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 a 130 V standoff voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 1.4 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - used to protect MOSFETs, ICs, and sensor interfaces in automotive and industrial control systems.
For engineers reviewing the SMAJ130CAHE3/61 datasheet, SMAJ130CAHE3/61 pinout, SMAJ130CAHE3/61 application, or SMAJ130CAHE3/61 equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, low thermal resistance (RθJL = 30 °C/W), MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional CA construction, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 μA at VWM) and fast response time (<1.0 ns), critical for suppressing ESD and inductive switching spikes.
The device delivers 400 W peak pulse power up to 78 V and derates to 300 W above that threshold, with clamping performance validated under standardized 10/1000 μs surge conditions. Thermal design relies on low RθJL (30 °C/W) and RθJA (120 °C/W) values, requiring minimum recommended pad layout for rated power dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuitry. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed breakdown threshold range; ensures reliable turn-on during overvoltage events. |
| VC @ IPPM | 209 V at 1.4 A - Clamped voltage during 10/1000 μs surge; determines maximum stress imposed on downstream components. |
| PPPM | 400 W (≤78 V), 300 W (>78 V) - Peak surge power handling capacity; defines transient energy absorption limit per pulse. |
| IFSM | 40 A - Non-repetitive forward surge current rating (8.3 ms half-sine); supports unidirectional fault tolerance where applicable. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive and high-ambient industrial environments. |
| MSL Level | Level 1 (J-STD-020) - No floor life limitation; compatible with standard reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H), cathode band omitted per bidirectional design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Transient current entry (either direction) | One terminal of symmetrical PN junction; accepts surge current regardless of polarity relative to other terminal. |
| Anode | Transient current exit (either direction) | Same physical terminal serves as return path during opposite-polarity surge; bidirectional conduction eliminates need for orientation-aware layout. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock - suitable for engine control, ADAS, and body electronics. |
| Glass passivated junction | Stable VBR tolerance and low leakage (<1.0 μA) across -55 °C to +150 °C; prevents parameter drift in harsh thermal environments. |
| 400 W peak pulse power | Withstands 10/1000 μs surges up to 1.4 A while limiting clamped voltage to 209 V - protects 130 V-rated power rails and interface ICs. |
| Low RθJL = 30 °C/W | Enables efficient heat transfer from junction to PCB copper pads; supports sustained operation near thermal limits with minimal derating. |
| Matte tin-plated leads | Ensures solderability per J-STD-002 and JESD 22-B102; compatible with lead-free reflow and meets JESD 201 Class 2 whisker resistance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA-M3/61 | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification. | No functional difference; selected when halogen-free compliance is mandated by OEM environmental policy. | Direct material substitution where halogen content must be minimized; same footprint, thermal, and electrical behavior. |
| SMCJ130CAHE3/61 | Higher 1500 W peak pulse power rating, larger SMC (DO-214AB) package, same VWM/VC values. | Used where higher single-pulse energy absorption is required, e.g., primary-side AC input protection or heavy-inductive loads. | Choose when surge duty cycle or energy level exceeds SMAJ130CAHE3/61's 400 W limit; requires PCB layout change due to larger footprint. |
Compared with SMAJ130CA-M3/61, the SMAJ130CAHE3/61 offers identical protection performance with standard RoHS compliance; versus SMCJ130CAHE3/61, it trades higher power handling for compact size and lower thermal mass - ideal for space-constrained automotive modules where 400 W suffices.

FAQ
What is the clamping voltage of SMAJ130CAHE3/61 under a 10/1000 μs surge?
The SMAJ130CAHE3/61 exhibits a maximum clamping voltage (VC) of 209 V when subjected to its rated peak pulse current of 1.4 A using the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88390 and defines the upper voltage limit imposed on protected circuitry during transient events. The SMAJ130CAHE3/61 maintains this clamping performance across its full operating temperature range.
Is SMAJ130CAHE3/61 suitable for automotive applications?
Yes, SMAJ130CAHE3/61 is AEC-Q101 qualified and explicitly designated for automotive use in Vishay's ordering nomenclature (HE3 suffix). It meets requirements for temperature cycling, mechanical shock, and humidity testing per AEC-Q101 Rev D, making it appropriate for engine control units, body electronics, and ADAS subsystems. The SMAJ130CAHE3/61 also supports MSL Level 1 handling and lead-free reflow compatibility required in modern automotive manufacturing.
How does the bidirectional nature of SMAJ130CAHE3/61 affect PCB layout?
The SMAJ130CAHE3/61 has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. Unlike unidirectional TVS diodes, it can be mounted without regard to anode/cathode alignment - simplifying layout, reducing assembly errors, and enabling use in AC-coupled or floating signal paths. This symmetry is confirmed in Vishay's "DEVICES FOR BIDIRECTION APPLICATIONS" section and applies specifically to all CA-suffixed SMAJ parts including SMAJ130CAHE3/61.
What is the thermal resistance from junction to lead (RθJL) for SMAJ130CAHE3/61?
The SMAJ130CAHE3/61 has a typical junction-to-lead thermal resistance (RθJL) of 30 °C/W, as specified in the Thermal Characteristics table of Vishay document 88390. This low value enables efficient heat conduction from the silicon die to the PCB copper pads through the leads, supporting reliable operation at elevated ambient temperatures. The SMAJ130CAHE3/61 achieves this with its DO-214AC package geometry and matte tin-plated terminations.
Does SMAJ130CAHE3/61 require special handling for moisture sensitivity?
No - SMAJ130CAHE3/61 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and may be stored and processed without dry pack or baking. Its maximum peak reflow temperature is 260 °C, fully compatible with standard lead-free soldering profiles. This moisture sensitivity classification is explicitly stated in the Mechanical Data section of Vishay's SMAJ5.0A–SMAJ188CA datasheet and applies directly to SMAJ130CAHE3/61.
