Product details
Overview
SMAJ130AE3/TR13 from Microsemi is a unidirectional surface-mount transient voltage suppressor (TVS) designed for primary and secondary lightning surge protection in DC power lines and signal interfaces. It features a 130 V standoff voltage (VWM), 144 V minimum breakdown voltage (VBR), clamps to ≤231 V at 209 A peak pulse current (IPP), and delivers 500 W peak pulse power (10/1000 µs). It is used in industrial power supplies, telecom line cards, and automotive body control modules requiring IEC61000-4-5 Class 1–4 compliance with 12 Ω or 42 Ω source impedance.
For engineers reviewing the SMAJ130AE3/TR13 datasheet, SMAJ130AE3/TR13 pinout, SMAJ130AE3/TR13 application, or SMAJ130AE3/TR13 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, standoff voltage alignment with system operating voltage, thermal derating on FR4 PCBs, and RoHS-compliant matte-tin termination compatibility with lead-free reflow profiles.
Technical Context
This TVS diode operates as a unidirectional avalanche clamp, triggered when reverse voltage exceeds its 144 V minimum breakdown threshold (IBR = 1 mA). Its sub-100 ps theoretical response time enables effective suppression of ESD (IEC61000-4-2) and EFT (IEC61000-4-4) transients before sensitive downstream circuitry is stressed.
It is rated for continuous operation from –65 °C to +150 °C, with thermal resistance of 15 °C/W junction-to-lead and 80 °C/W junction-to-ambient on standard FR4 (1 oz Cu). The DO-214AC package supports 500 W peak pulse power at 25 °C but requires derating above 75 °C ambient per the published curve.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 130 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; sets upper limit for protected circuit DC rail. |
| VBR (Min @ IBR) | 144 V @ 1 mA - Guaranteed avalanche onset voltage; defines minimum overvoltage threshold for clamping activation. |
| VC @ IPP | 231 V @ 209 A (10/1000 µs) - Maximum clamped voltage seen by protected load during worst-case surge; must stay below downstream IC's absolute max rating. |
| PPP | 500 W - Peak pulse power handling capability under standardized 10/1000 µs waveform; determines survivability against lightning-induced surges. |
| IPP | 209 A - Peak surge current the device passes while clamping to ≤231 V; used with source impedance to calculate let-through energy. |
| TJ Range | –65 °C to +150 °C - Full operational junction temperature range; supports under-hood automotive and industrial outdoor deployments. |
| Package | DO-214AC (SMA) - Standardized surface-mount outline with wide leads for low thermal resistance and high surge current path integrity. |
Pinout & Package
DO-214AC (SMA) package with cathode-indicated band; void-free thermosetting epoxy case (UL94V-0), matte-tin-plated C-bend leads solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Surge return path to ground | Connected to system ground plane; carries full surge current during clamping event; requires low-inductance layout. |
| Cathode | Protected line input | Connected to line being protected (e.g., 12 V or 24 V rail); polarity marking ensures correct orientation for unidirectional operation. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ130AHE3/TR13 | Same electrical specs, but with enhanced screening per MIL-PRF-19500 JANTX level (MX prefix option available); higher reliability testing including HTRB and surge cycling. | Required for aerospace, defense, or avionics-grade designs needing extended temperature cycling (-55 °C to +125 °C, 10×) and post-surge parameter verification. | Select SMAJ130AHE3/TR13 when mission-critical reliability and traceable screening records are mandatory; otherwise, SMAJ130AE3/TR13 suffices for commercial/industrial use. |
| SMCJ130A | Same VWM, VBR, and VC, but in larger DO-214AB (SMC) package; 1500 W peak power rating and lower thermal resistance (10 °C/W junction-to-lead). | Preferred where higher surge repetition rate, longer surge duration, or improved thermal margin is needed - e.g., in high-power motor drives or utility metering. | Choose SMCJ130A if board space allows and thermal/power robustness outweighs size constraints; SMAJ130AE3/TR13 remains optimal for space-constrained 500 W applications. |
Compared with SMAJ130AHE3/TR13, the SMAJ130AE3/TR13 omits military-grade screening but retains identical clamping performance and RoHS compliance; versus SMCJ130A, it trades 1000 W extra pulse power and better thermal dissipation for 40% smaller footprint - making it ideal for compact, cost-sensitive industrial designs where 500 W surge capacity is sufficient.

FAQ
What is the clamping voltage of SMAJ130AE3/TR13 at its rated peak pulse current?
The SMAJ130AE3/TR13 clamps to a maximum of 231 V when subjected to its rated 209 A peak pulse current (10/1000 µs waveform). This value is measured across the device terminals under standardized test conditions and defines the highest voltage that will appear on the protected line during a worst-case surge event. Designers must ensure this clamping voltage remains safely below the absolute maximum ratings of downstream components such as DC-DC controllers or microcontroller power pins.
Is SMAJ130AE3/TR13 unidirectional or bidirectional, and how is polarity marked?
SMAJ130AE3/TR13 is a unidirectional TVS diode, indicated by the "A" suffix in its part number. Polarity is marked by a cathode band on the DO-214AC package body; the banded end connects to the protected line (e.g., +12 V or +24 V rail), while the unbanded end connects to ground. Bidirectional variants carry a "C" or "CA" suffix (e.g., SMAJ130CA) and lack polarity marking.
Does SMAJ130AE3/TR13 meet IEC61000-4-5 for lightning surge immunity?
Yes, SMAJ130AE3/TR13 is validated for secondary lightning surge protection per IEC61000-4-5. It supports Class 1 (42 Ω source) up to 130 V standoff and Class 4 (12 Ω source) up to 12 V standoff. For a 130 V system, it satisfies Class 1 requirements - commonly applied in telecom infrastructure and industrial control panels where moderate coupling impedance is expected.
What is the maximum steady-state power dissipation of SMAJ130AE3/TR13 on a standard FR4 PCB?
When mounted on a standard FR4 printed circuit board with 1 oz copper and the recommended pad layout, SMAJ130AE3/TR13 dissipates up to 1.56 W at 25 °C ambient temperature. At higher ambient temperatures, power rating must be derated per the published thermal curve - for example, to ~0.8 W at 75 °C ambient. This rating applies only to continuous DC stress, not transient surge conditions.
Can SMAJ130AE3/TR13 be used in lead-free reflow processes?
Yes, SMAJ130AE3/TR13 features RoHS-compliant matte-tin plating ("e3" suffix) and is qualified for lead-free reflow soldering at 260 °C for up to 10 seconds. Its void-free thermosetting epoxy body (UL94V-0) withstands multiple thermal cycles without delamination or cracking, making it suitable for standard SMT assembly lines using Pb-free profiles.
