Product details
Overview
SMAJ130CAHE3/5A 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 power rails.
For engineers reviewing the SMAJ130CAHE3/5A datasheet, SMAJ130CAHE3/5A pinout, SMAJ130CAHE3/5A application, or SMAJ130CAHE3/5A equivalent, this device delivers AEC-Q101 qualified transient suppression for bidirectional DC bus protection, with verified thermal resistance (RθJA = 120 °C/W), low leakage (<1.0 μA at VWM), and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling robust protection without polarity sensitivity on AC-coupled or floating lines. Its glass-passivated junction ensures stable VBR tolerance (±5 %) and fast response time (<1.0 ns), while the 120 °C/W junction-to-ambient thermal resistance requires careful PCB copper pad design (0.2" × 0.2") to sustain 400 W surge capability.
The device meets MSL Level 1 per J-STD-020 with 260 °C reflow peak, supports 40 A IFSM surge current (8.3 ms half-sine), and exhibits a +0.108 %/°C temperature coefficient of VBR, ensuring predictable clamping behavior over -55 °C to +150 °C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - Maximum continuous reverse working voltage before conduction begins; defines safe operating margin below clamping threshold. |
| VBR (min/max) | 144 V / 159 V at 1 mA - Confirmed breakdown range ensures reliable turn-on during transients without premature conduction. |
| VC @ IPPM | 209 V at 1.4 A - Clamped voltage under 10/1000 μs surge; limits downstream component stress to ≤209 V. |
| PPPM | 400 W - Peak pulse power handling with 10/1000 μs waveform; derates to 300 W above 78 V per spec. |
| IDR @ VWM | <1.0 μA - Ultra-low reverse leakage preserves signal integrity and minimizes standby power loss. |
| TJ max. | +150 °C - Maximum junction temperature enables operation in under-hood automotive and high-ambient industrial environments. |
| RθJA | 120 °C/W - Thermal resistance dictates minimum required copper pad area (0.2" × 0.2") for full 400 W rating. |
Pinout & Package

Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
|
Use Scenario: Suppressing load-dump transients (up to 120 V, 400 ms) on 12 V battery-fed ECUs and lighting control modules. IC Role / Device Role / Timing Role: Bidirectional clamping element placed across power input pins to limit voltage excursions during alternator regulation failure. Use Value: Limits peak rail voltage to ≤209 V, preventing damage to 36 V-rated CAN transceivers and microcontrollers. |
Use Scenario: Protecting analog front-end inputs of pressure/temperature sensors connected to noisy factory floor PLCs. IC Role / Device Role / Timing Role: Low-capacitance TVS shunting ESD (IEC 61000-4-2) and fast-switching noise on 0–5 V sensor outputs. Use Value: Sub-1.0 μA leakage avoids DC offset errors; 1.0 ns response prevents transient coupling into ADC sampling windows. |
| Telecom DC Power Feeds | Consumer Device USB/DC Jack Protection |
|
Use Scenario: Guarding PoE-powered network switches against lightning-induced surges on 48 V DC input lines. IC Role / Device Role / Timing Role: Primary overvoltage clamp upstream of DC-DC converters and hot-swap controllers. Use Value: 400 W rating handles multi-kA induced surges; bidirectional symmetry eliminates polarity dependency in floating DC feeds. |
Use Scenario: Safeguarding USB-C PD port and barrel jack inputs in portable audio equipment from user-handling ESD and adapter transients. IC Role / Device Role / Timing Role: First-line transient suppressor mounted directly at connector entry point. Use Value: SMA footprint allows compact placement; AEC-Q101 qualification ensures robustness beyond consumer-grade reliability expectations. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130CA-M3/5A | Halogen-free, RoHS-compliant variant; identical electrical specs and AEC-Q101 qualification. | No functional difference; selected when halogen-free material compliance is mandated by OEM or regional regulations. | Choose SMAJ130CA-M3/5A if halogen-free content is required; otherwise SMAJ130CAHE3/5A satisfies standard automotive and industrial specs. |
| SMBJ130CAHE3/5A | Same VWM/VC ratings but in SMB (DO-214AA) package - 2.5 mm wider, higher RθJA (100 °C/W), lower PPPM (600 W). | Better surge handling but larger footprint; less suitable for space-constrained automotive modules. | Select SMBJ130CAHE3/5A only when board layout permits larger package and higher 600 W surge margin is needed; SMAJ130CAHE3/5A optimizes size vs. 400 W requirement. |
Compared with SMAJ130CA-M3/5A, the HE3 suffix offers identical performance with standard RoHS compliance; versus SMBJ130CAHE3/5A, the SMAJ version trades 200 W peak power for 30 % smaller PCB area and tighter thermal management constraints.

FAQ
What is the clamping voltage of SMAJ130CAHE3/5A at its rated peak pulse current?
The SMAJ130CAHE3/5A has a maximum clamping voltage (VC) of 209 V at its specified peak pulse current (IPPM) of 1.4 A under a 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 surge events. The SMAJ130CAHE3/5A maintains this clamping performance across its full operating temperature range (-55 °C to +150 °C) with minimal drift due to its +0.108 %/°C VBR coefficient.
Is SMAJ130CAHE3/5A suitable for automotive applications?
Yes, SMAJ130CAHE3/5A is AEC-Q101 qualified and explicitly designated for automotive use with ordering code suffix HE3. It meets stringent requirements for thermal cycling, mechanical shock, and humidity resistance, and is commonly deployed in engine control units, body control modules, and infotainment power rails. The SMAJ130CAHE3/5A also complies with RoHS and supports lead-free reflow up to 260 °C per J-STD-020 MSL Level 1.
How does the bidirectional configuration of SMAJ130CAHE3/5A affect its circuit implementation?
The bidirectional configuration of SMAJ130CAHE3/5A means it functions identically in both polarities - no cathode marking is present, and it clamps transients regardless of voltage polarity across its terminals. This simplifies layout on AC-coupled lines, floating grounds, or differential buses where polarity cannot be guaranteed. Unlike unidirectional variants, SMAJ130CAHE3/5A eliminates the need for orientation verification during automated placement and avoids reverse-bias failure modes in unpredictable signal environments.
What is the thermal resistance and recommended PCB layout for SMAJ130CAHE3/5A to achieve full 400 W rating?
SMAJ130CAHE3/5A has a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, which requires mounting on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to sustain its full 400 W peak pulse power rating. Reducing pad area increases thermal impedance and forces derating per Figure 2 in Vishay document 88390. The SMAJ130CAHE3/5A's RθJL of 30 °C/W further supports heat transfer through leads when connected to internal ground/power planes.
Does SMAJ130CAHE3/5A have any special handling or packaging requirements?
SMAJ130CAHE3/5A is supplied in 13" diameter plastic tape and reel (package code /5A) with 7500 units per reel, and is MSL Level 1 compliant - meaning it may be stored indefinitely at ambient conditions and processed using standard lead-free reflow profiles peaking at 260 °C. No baking or dry-packaging is required. The matte tin-plated leads meet J-STD-002 solderability standards, and whisker resistance is certified per JESD 201 Class 2.
