Product details
Overview
SMAJ130AHE3_A/H from Vishay General Semiconductor is a unidirectional 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 stand-off voltage (VWM), 144–159 V breakdown voltage (VBR) at 1 mA, 209 V maximum clamping voltage (VC) at 1.4 A peak pulse current (IPPM), and 400 W peak pulse power rating with 10/1000 μs waveform - suitable for protecting MOSFETs, ICs, and sensor interfaces in industrial power supplies and automotive control modules.
For engineers reviewing the SMAJ130AHE3_A/H datasheet, SMAJ130AHE3_A/H pinout, SMAJ130AHE3_A/H application, or SMAJ130AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, thermal resistance (RθJA = 120 °C/W), junction temperature range (−55 to +150 °C), and compatibility with automated SMT placement on standard PCB copper pad layouts.
Technical Context
This TVS diode operates as a fast-acting shunt protector: under normal bias it presents high impedance (>1 μA leakage at 130 V), but triggers into low-impedance conduction when transient voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance and long-term reliability under repetitive surge stress.
The device delivers 400 W peak pulse power up to 78 V and derates to 300 W above that level, with clamping performance validated per ANSI/IEEE C62.35 standards. It meets MSL Level 1 per J-STD-020 and supports lead-free reflow profiles with peak temperature up to 260 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse operating voltage before significant leakage begins |
| VBR min/max | 144 V / 159 V at 1 mA - guaranteed breakdown window defining turn-on consistency across production lots |
| VC @ IPPM | 209 V at 1.4 A - clamped voltage during worst-case 10/1000 μs surge, limiting downstream component stress |
| PPPM | 400 W (≤78 V), 300 W (>78 V) - peak transient energy absorption capability under standardized waveform |
| ID @ VWM | 1.0 μA - ultra-low reverse leakage ensuring minimal standby power loss in high-impedance circuits |
| TJ max | +150 °C - maximum junction temperature enabling operation in under-hood automotive or industrial enclosures |
| RθJA | 120 °C/W - thermal resistance from junction to ambient on standard 0.2" × 0.2" copper pads, guiding heatsinking decisions |

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: 12 V/24 V battery-fed ECUs exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Primary shunt clamp on main power input, placed upstream of DC-DC converters and microcontrollers. Use Value: Limits transient excursions to ≤209 V, preventing latch-up or gate oxide damage in downstream MOSFETs and PMICs. |
Use Scenario: Analog sensor outputs (e.g., pressure, temperature) routed across noisy motor drive zones. IC Role / Device Role / Timing Role: Low-capacitance (<50 pF) line protector on differential or single-ended signal traces. Use Value: Clamps ESD and inductive kickback without distorting millivolt-level signals due to sub-μA leakage at 130 V. |

Use Scenario: Secondary-side DC bus in USB-C PD adapters where space-constrained layout demands compact SMT protection. IC Role / Device Role / Timing Role: Unidirectional TVS placed between isolated DC output and USB port controller IC. Use Value: Provides UL 497B recognized protection while occupying only 2.8 mm × 4.5 mm footprint. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130A-E3/61 | Commercial-grade (non-AEC-Q101), same VWM/VBR/VC specs, identical SMA package and pinout | Lacks automotive qualification; unsuitable for under-hood or safety-critical modules | Select when cost sensitivity outweighs automotive compliance requirements |
| SMBJ130AHE3_A/H | Same electrical specs but SMB (DO-214AA) package - 30 % larger footprint, lower RθJA (90 °C/W) | Better thermal performance in high-power or high-ambient environments; requires PCB layout change | Choose when sustained surge duty cycle or elevated ambient temperature exceeds SMAJ130AHE3_A/H thermal margin |
Compared with SMAJ130A-E3/61, SMAJ130AHE3_A/H adds AEC-Q101 qualification for automotive use; compared with SMBJ130AHE3_A/H, it trades thermal margin for board space savings - making SMAJ130AHE3_A/H optimal for space-constrained, automotive-grade 130 V rail protection.

FAQ
What is the clamping voltage of SMAJ130AHE3_A/H at its rated peak pulse current?
The SMAJ130AHE3_A/H has a maximum clamping voltage (VC) of 209 V when subjected to its specified peak pulse current (IPPM) of 1.4 A under the 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees consistent overvoltage limiting behavior across production units - critical for ensuring downstream ICs remain within safe operating voltage margins during surge events.
Is SMAJ130AHE3_A/H qualified for automotive applications?
Yes, SMAJ130AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3" and documentation in datasheet revision 09-Jan-2024. This qualification covers stress tests including temperature cycling, high-temperature operating life, and mechanical shock - validating its suitability for engine control units, body electronics, and ADAS subsystems where reliability under thermal and vibration stress is mandatory.
What is the thermal resistance of SMAJ130AHE3_A/H, and how does it affect PCB layout?
SMAJ130AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout; reducing copper area increases thermal impedance and risks exceeding the +150 °C maximum junction temperature during repetitive surges - so designers must maintain specified pad dimensions and avoid excessive trace narrowing near terminals.
How does the unidirectional configuration of SMAJ130AHE3_A/H impact circuit design?
The unidirectional configuration of SMAJ130AHE3_A/H requires correct polarity orientation: cathode must connect to system ground or the lower-potential rail, while anode connects to the protected line. This enables forward conduction during negative transients relative to ground - unlike bidirectional variants, it does not protect against reverse-voltage faults, making it ideal for DC power rails where polarity is fixed and only positive-going surges are expected.
What packaging and moisture sensitivity level applies to SMAJ130AHE3_A/H?
SMAJ130AHE3_A/H is supplied in 7" diameter plastic tape and reel (package code H, base quantity 1800 units) and is rated MSL Level 1 per J-STD-020 - meaning it may be stored indefinitely at ambient conditions and placed directly into reflow without pre-baking. Its matte tin-plated leads comply with J-STD-002 and JESD 22-B102, supporting reliable solder joint formation in lead-free processes.
