Product details
Overview
SMAJ130CAE3/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 2.2 A peak pulse current, and 500 W peak pulse power rating per 10/1000 µs waveform - deployed in industrial power supplies, telecom interfaces, and automotive body electronics.
For engineers reviewing the SMAJ130CAE3/TR13 datasheet, SMAJ130CAE3/TR13 pinout, SMAJ130CAE3/TR13 application, or SMAJ130CAE3/TR13 equivalent, key selection criteria include bidirectional clamping capability, IEC61000-4-5 Class 1 compliance with 42 Ω source impedance, RoHS-compliant matte-tin plating, DO-214AC package thermal resistance (15 °C/W junction-to-lead), and tape-and-reel packaging (TR13 = 7-inch reel, 750 pcs).
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling robust protection without polarity sensitivity in AC-coupled or floating bus applications. Its <100 ps theoretical response time (unidirectional) and <5 ns for bidirectional configurations ensures sub-nanosecond suppression of fast transients such as ESD (IEC61000-4-2) and EFT (IEC61000-4-4).
The device sustains 500 W peak pulse power at 25 °C with 0.01% duty cycle, and derates linearly above 25 °C per the published thermal curve. Junction-to-lead thermal resistance is 15 °C/W, supporting reliable operation up to +150 °C storage and -65 °C operating temperature, with moisture sensitivity level 1 (no dry pack required).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 130 V - maximum continuous reverse working voltage before conduction begins; defines safe operating margin for 120 VAC-derived DC rails. |
| VBR min @ IBR | 144 V @ 1 mA - guaranteed minimum breakdown threshold; ensures predictable turn-on during overvoltage events. |
| VC @ IPP | 231 V @ 2.2 A - clamped voltage under 10/1000 µs surge; limits downstream component stress to ≤231 V. |
| PPP | 500 W - peak pulse power handling capacity; supports high-energy surges like induced lightning transients. |
| ID @ VWM | 2.2 µA - leakage current at rated standoff; negligible power loss in standby, critical for low-power sensor nodes. |
| TJ range | -65 °C to +150 °C - extended temperature capability enables use in under-hood automotive and outdoor telecom enclosures. |
| Package | DO-214AC (SMA) - industry-standard surface-mount outline with wide leads for enhanced thermal dissipation and mechanical reliability. |
Pinout & Package
DO-214AC (SMA) package: void-free thermosetting epoxy body (UL94V-0), C-bend (modified J-bend) leads with RoHS-compliant annealed matte-tin plating, cathode marking omitted on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: 120 VAC-derived 170 VDC bulk supply rail exposed to load dump and lightning-induced surges. IC Role / Device Role / Timing Role: Bidirectional TVS placed between DC+ and chassis ground to clamp positive/negative transients before they reach DC-DC converters. Use Value: Limits transient voltage to ≤231 V, preventing damage to 200 V-rated input capacitors and MOSFETs while maintaining >130 V nominal operation margin. |
Use Scenario: RS-485 data line pair (A/B) in outdoor base station equipment subject to induced RF and EFT bursts. IC Role / Device Role / Timing Role: Two SMAJ130CAE3/TR13 devices used differentially (A-to-B) and common-mode (A-to-GND, B-to-GND) for full-spectrum surge suppression. Use Value: Sub-5 ns response ensures clamping occurs before transceiver ICs (e.g., SN65HVD72) experience latch-up, preserving communication integrity during 4 kV EFT events. |
| Automotive Body Control Module (BCM) CAN Bus | Renewable Energy Inverter DC Link Monitoring |
Use Scenario: CAN_H/CAN_L lines in BCM exposed to ISO 7637-2 pulse 1/2a/3a transients during vehicle battery disconnect/reconnect. IC Role / Device Role / Timing Role: Bidirectional TVS installed across CAN differential pair to absorb negative-going spikes and positive overshoot simultaneously. Use Value: 231 V clamping protects 3.3 V CAN transceivers via series current-limiting resistors, avoiding reliance on internal clamp diodes alone. |
Use Scenario: Voltage sense input (0–250 V range) monitoring DC link in solar inverter, vulnerable to switching noise and grid fault coupling. IC Role / Device Role / Timing Role: SMAJ130CAE3/TR13 placed between sense node and ground to shunt transients exceeding 130 V before reaching precision ADC front-end. Use Value: 2.2 µA leakage at 130 V ensures minimal measurement error (<0.001% gain shift) in 16-bit isolated voltage sensing circuits. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ130CA | Same VWM/VC/PPP, but non-RoHS tin-lead plating; no "e3" suffix; TR13 not standard - typically supplied in bulk or different reel size. | Acceptable where RoHS exemption applies (e.g., legacy aerospace); requires reflow profile adjustment for Pb-based solder. | Select when legacy qualification or Pb-containing assembly process mandates compatibility with MIL-PRF-19500 screening options. |
| Vishay SMAJ130CAHE3_A/H | Identical electrical specs and RoHS compliance; differs in JEDEC-compliant DO-214AC footprint (max 2.66 mm width vs. Microsemi's 2.79 mm), slightly lower thermal resistance (14 °C/W). | Drop-in replacement only if PCB pad layout accommodates tighter width tolerance; preferred for high-volume consumer designs with strict JEDEC adherence. | Select when JEDEC footprint compliance is mandatory and thermal margin below 15 °C/W is required for sustained 500 W pulse duty cycles. |
Compared with Littelfuse SMAJ130CA and Vishay SMAJ130CAHE3_A/H, SMAJ130CAE3/TR13 offers verified tape-and-reel consistency for SMT line integration, extended thermal margin via wider lead geometry, and factory-screened RoHS compliance traceability - making it optimal for industrial OEMs requiring full supply chain documentation and long-term BOM stability.

FAQ
What does the "CA" suffix indicate in SMAJ130CAE3/TR13?
The "CA" suffix denotes a bidirectional configuration - meaning SMAJ130CAE3/TR13 provides symmetrical clamping for both positive and negative transients without polarity dependence. Unlike unidirectional variants (e.g., SMAJ130A), it has no cathode marking and is used across differential lines or AC-coupled nodes where voltage polarity reverses. This is confirmed in Microsemi's datasheet revision L, page 1.
Is SMAJ130CAE3/TR13 compatible with lead-free reflow processes?
Yes, SMAJ130CAE3/TR13 uses RoHS-compliant annealed matte-tin plating and is rated for solder temperatures up to 260 °C for 10 seconds - fully compatible with standard lead-free reflow profiles (e.g., IPC/JEDEC J-STD-020). Its UL94V-0 epoxy body withstands thermal cycling without delamination, and moisture sensitivity level 1 eliminates pre-bake requirements.
How does SMAJ130CAE3/TR13 meet IEC61000-4-5 Class 1 requirements?
SMAJ130CAE3/TR13 meets IEC61000-4-5 Class 1 (4 kV) with 42 Ω source impedance, as specified in Microsemi's datasheet page 1 under "Secondary lightning protection per IEC61000-4-5". Its 231 V clamping voltage at 2.2 A ensures protected circuits remain below destructive thresholds during standardized 1.2/50 µs open-circuit voltage and 8/20 µs current waveforms.
What is the thermal resistance of SMAJ130CAE3/TR13, and how does it affect layout?
SMAJ130CAE3/TR13 has a junction-to-lead thermal resistance (RθJL) of 15 °C/W, measured with recommended DO-214AC pad layout (2.57–2.79 mm width, 4.93–5.48 mm length on FR4 with 1 oz Cu). To maintain this value, PCB copper area must match the datasheet's footprint - undersized pads increase thermal resistance, risking premature failure under repeated 500 W pulses.
Can SMAJ130CAE3/TR13 replace SMAJ130A in an existing design?
No - SMAJ130CAE3/TR13 is bidirectional while SMAJ130A is unidirectional; substituting them requires verifying circuit topology. SMAJ130A conducts only in reverse bias and requires correct cathode orientation, whereas SMAJ130CAE3/TR13 clamps equally in both directions and has no polarity marking. Using SMAJ130CAE3/TR13 in place of SMAJ130A may cause unintended conduction in DC-biased rails.
