Product details
Overview
SMAJ130CE3/TR13 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for secondary lightning and ESD/EFT protection in DC power rails and signal lines. It features a 130 V standoff voltage (VWM), 144 V minimum breakdown voltage (VBR), 231 V clamping voltage (VC) at 209 A peak pulse current, and 500 W peak pulse power rating per 10/1000 µs waveform - deployed in industrial power supplies and telecom interface circuits.
For engineers reviewing the SMAJ130CE3/TR13 datasheet, SMAJ130CE3/TR13 pinout, SMAJ130CE3/TR13 application, or SMAJ130CE3/TR13 equivalent, key selection criteria include bidirectional clamping capability, IEC61000-4-5 Class 1–4 compliance with 12 Ω/42 Ω source impedances, RoHS-compliant "e3" termination, and DO-214AC package compatibility with standard SMT reflow profiles.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its <100 ps theoretical response time (unidirectional) and <5 ns for bidirectional operation ensures suppression before sensitive downstream circuitry sustains damage from fast transients such as ESD (IEC61000-4-2) or EFT (IEC61000-4-4).
The device is rated for 500 W peak pulse power at 25 °C with derating to zero at 150 °C junction temperature, supported by 15 °C/W junction-to-lead thermal resistance. It withstands 42 Ω source impedance lightning surges up to Class 1 (SMAJ130CE3/TR13 included) and 12 Ω surges up to Class 2 per IEC61000-4-5, with standby leakage current ≤2.2 µA at 130 VWM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Standoff) | 130 V - Maximum continuous reverse working voltage before clamping initiates |
| VBR (Min) | 144 V @ 1 mA - Ensures reliable turn-on margin above operating rail |
| VC @ IPP | 231 V @ 209 A - Clamped voltage during 10/1000 µs surge limits stress on protected ICs |
| PPP | 500 W - Peak transient energy absorption capacity under standardized surge waveform |
| ID @ VWM | ≤2.2 µA - Negligible leakage current preserves efficiency in high-impedance bias networks |
| Package | DO-214AC (SMA) - Industry-standard surface-mount outline with 1.70–2.26 mm body width and J-bend leads |
| Operating Temp | −65 °C to +150 °C - Supports deployment in extended-temperature industrial and automotive under-hood environments |
Pinout & Package
DO-214AC (SMA) package: surface-mount, void-free thermosetting epoxy body (UL94V-0), matte-tin RoHS-compliant plating, C-bend (modified J-bend) leads, cathode band omitted for bidirectional construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode | Bidirectional terminal pair | Identical electrical behavior in both directions; no polarity marking; connects across protected line and ground |
| Case | Non-electrical mechanical structure | No internal connection; serves only as thermal path and mechanical anchor; not used for circuit routing |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection of AC signals or floating buses without external polarity management |
| IEC61000-4-5 compliance | Validated for secondary lightning immunity up to Class 1 (42 Ω) and Class 2 (12 Ω) source impedances |
| RoHS-compliant "e3" finish | Meets EU Directive 2011/65/EU with annealed matte-tin plating compatible with Pb-free reflow |
| Moisture sensitivity Level 1 | Zero dry-pack requirement per IPC/JEDEC J-STD-020B - simplifies handling and storage logistics |
| Tape-and-reel packaging | Supplied in EIA-481-1-A compliant 12 mm tape, 750 units per 7-inch reel (TR13 suffix) |
Applications
| Industrial Power Input Protection | Telecom Line Interface |
|---|---|
Use Scenario: 24–48 V DC input stage of programmable logic controllers exposed to load dump and inductive switching transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between input rail and chassis ground, upstream of DC-DC converters and microcontrollers. Use Value: Limits transient voltage to ≤231 V during 209 A surges, preventing latch-up or gate oxide rupture in downstream MOSFETs and PMICs. | Use Scenario: RS-485 data lines in outdoor base stations subject to induced RF and nearby lightning strikes. IC Role / Device Role / Timing Role: Bidirectional shunt protector across differential pair (A/B) and ground, absorbing common-mode surges. Use Value: Symmetric clamping maintains signal integrity during ±231 V transients, preserving receiver common-mode range and avoiding data corruption. |
| Automotive Body Control Module | Medical Sensor Signal Conditioning |
Use Scenario: 12 V battery-supplied lighting control modules enduring ISO 7637-2 Pulse 1/2a/5a transients. IC Role / Device Role / Timing Role: Secondary protection stage after fuse and LC filter, directly at MCU GPIO and CAN transceiver supply pins. Use Value: Sub-5 ns response time intercepts fast-edge spikes before they propagate into low-voltage logic domains. | Use Scenario: Analog front-end of patient-connected ECG amplifiers requiring ultra-low leakage and high CMRR. IC Role / Device Role / Timing Role: Low-leakage (≤2.2 µA) bidirectional clamp on sensor input lines referenced to isolated analog ground. Use Value: Prevents ESD-induced baseline shift or amplifier saturation while adding <0.5 pF capacitance per terminal (half of unidirectional 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 |
|---|---|---|---|
| SMAJ130A-E3/5A (Vishay) | Unidirectional; 130 VWM, 144 VBR, 231 VC @ 209 A; same DO-214AC package | Requires explicit polarity assignment; unsuitable for AC or floating nodes | Select when protecting unidirectional DC rails with defined ground reference and lower BOM cost priority |
| 1.5SMC130CA (ON Semiconductor) | Bidirectional; 130 VWM, 144 VBR, 230 VC @ 217 A; DO-214AB (SMC) package - 2.54 mm wider body | Larger footprint; higher thermal mass but incompatible with SMA land patterns | Choose only if board layout accommodates SMC pad dimensions and higher surge margin (217 A vs. 209 A) is critical |
Compared with SMAJ130CE3/TR13, the Vishay SMAJ130A-E3/5A offers identical electrical specs but lacks bidirectional symmetry, while the ON Semiconductor 1.5SMC130CA provides marginally higher surge current rating but requires PCB redesign due to DO-214AB footprint mismatch.

FAQ
What does the "C" and "E3" suffix mean in SMAJ130CE3/TR13?
The "C" denotes bidirectional configuration - identical clamping behavior in both polarities, essential for AC or floating signal protection. The "E3" indicates RoHS-compliant matte-tin plating per EU Directive 2011/65/EU, qualified for lead-free reflow soldering. Both suffixes are integral to SMAJ130CE3/TR13's specification and cannot be omitted without changing device functionality or compliance status.
Is SMAJ130CE3/TR13 suitable for IEC61000-4-5 Class 4 lightning protection?
No - SMAJ130CE3/TR13 supports IEC61000-4-5 Class 1 (42 Ω source) and Class 2 (12 Ω source) only. Per Microsemi documentation, Class 4 compliance is limited to SMAJ12A and lower standoff voltages. Using SMAJ130CE3/TR13 for Class 4 would exceed its specified clamping and energy-handling limits, risking catastrophic failure during standardized surge testing.
What is the thermal resistance and maximum power dissipation of SMAJ130CE3/TR13?
SMAJ130CE3/TR13 has a junction-to-lead thermal resistance of 15 °C/W and junction-to-ambient resistance of 80 °C/W on FR4 with 1 oz Cu and recommended footprint. Steady-state power dissipation is 1.56 W at 25 °C ambient and 5 W at 75 °C lead temperature. These values define safe continuous operation limits - exceeding them risks thermal runaway during repeated transient events.
Does SMAJ130CE3/TR13 have polarity markings on the package?
No - SMAJ130CE3/TR13 is a bidirectional TVS and carries no cathode band or polarity marking, per Microsemi's mechanical specification. This distinguishes it from unidirectional variants (e.g., SMAJ130A) which use a band to indicate cathode. Board layout must treat both terminals as functionally identical, with symmetric placement relative to the protected node and ground.
What is the moisture sensitivity level (MSL) and reflow profile for SMAJ130CE3/TR13?
SMAJ130CE3/TR13 is rated MSL Level 1 per IPC/JEDEC J-STD-020B, meaning it may be stored indefinitely at ≤30 °C/60% RH without dry packing or baking. Reflow peak temperature is 260 °C for ≤10 seconds - fully compatible with standard Pb-free profiles. No floor life restrictions apply, simplifying manufacturing logistics versus higher-MSL discrete components.
