Product details
Overview
SMAJ60CE3/TR13 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for robust ESD, EFT, and secondary lightning surge protection in DC power rails and signal lines. It features a 60 V standoff voltage (VWM), 107 V clamping voltage (VC) at 4.7 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 SMAJ60CE3/TR13 datasheet, SMAJ60CE3/TR13 pinout, SMAJ60CE3/TR13 application, or SMAJ60CE3/TR13 equivalent, key selection criteria include bidirectional clamping capability, IEC61000-4-2/4-4/4-5 compliance, DO-214AC package thermal performance, and RoHS-compliant matte-tin terminations with tape-and-reel delivery (TR13).
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with breakdown occurring at ≥66.7 V in either direction when tested at 1 mA (IBR). Its sub-5 ns response time enables effective suppression of fast transients including ESD events and inductive switching spikes.
Thermal design relies on low junction-to-lead resistance (15 °C/W) and recommended FR4 PCB footprint; steady-state power dissipation is 1.56 W at 25 °C ambient and 5 W at 75 °C lead temperature. The device meets IEC61000-4-5 Class 1 (42 Ω source) up to 60 V standoff, and Class 2 (12 Ω source) up to 30 V standoff.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 60 V - Maximum continuous reverse working voltage before leakage exceeds 5 µA; defines safe operating rail margin. |
| VBR min | 66.7 V @ 1 mA - Minimum breakdown voltage ensures reliable conduction onset during overvoltage events. |
| VC @ IPP | 107 V @ 4.7 A - Clamping voltage limits downstream component stress during 10/1000 µs surges. |
| PPP | 500 W - Peak pulse power handling capacity determines survivability under standardized surge waveforms. |
| IPP | 4.7 A - Peak pulse current derived from PPP/VC; used to size PCB trace and grounding paths. |
| TJ range | –65 °C to +150 °C - Full operational temperature range supports deployment in harsh industrial environments. |
| Package | DO-214AC (SMA) - Standardized surface-mount outline with wide leads for thermal dissipation and mechanical reliability. |
Pinout & Package
DO-214AC (SMA) package: void-free thermosetting epoxy body (UL94V-0), C-bend tin-lead or RoHS-compliant matte-tin plated terminals, cathode marking absent on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional transient path | Both terminals function identically; no polarity dependency - simplifies layout and eliminates orientation errors. |
| Case / Body | Thermal and mechanical interface | Non-electrical; provides mechanical anchoring and heat conduction to PCB copper via wide lead contact area. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Enables single-device protection on AC-coupled or floating lines without polarity constraints. |
| IEC61000-4-2/4-4/4-5 compliance | Validated for system-level ESD (±8 kV contact), EFT (±2 kV), and secondary lightning (Class 1, 42 Ω source). |
| RoHS-compliant "e3" termination | Matte-tin plating meets JEDEC J-STD-020B Level 1 moisture sensitivity - no dry pack required. |
| 500 W 10/1000 µs rating | Supports high-energy surge immunity in 24–48 V industrial control and PoE-powered equipment. |
| Tape-and-reel packaging (TR13) | 2500 units per 13-inch reel - optimized for automated SMT placement and inventory management. |
Applications
| Industrial Power Supply Input Protection | Telecom Line Interface Protection |
|---|---|
Use Scenario: 48 V DC input stage of programmable logic controller (PLC) power module exposed to load dump and field wiring transients. IC Role / Device Role / Timing Role: Bidirectional TVS placed across input rails to clamp positive/negative surges before upstream DC-DC converter. Use Value: Limits voltage excursion to ≤107 V during 4.7 A surges, preventing damage to input MOSFETs and controller ICs rated for 65 V max. |
Use Scenario: RS-485 data line pair in outdoor base station equipment subject to induced lightning surges. IC Role / Device Role / Timing Role: Paired SMAJ60CE3/TR13 devices (one per line) referenced to common ground to suppress differential-mode transients. Use Value: Symmetric clamping maintains signal integrity while meeting IEC61000-4-5 Class 1 requirements for 42 Ω source impedance. |
| Automotive Body Control Module (BCM) CAN Bus | Medical Equipment Sensor Interface |
Use Scenario: CAN_H/CAN_L lines in non-safety-critical BCM unit exposed to battery transients and ESD during service. IC Role / Device Role / Timing Role: Low-capacitance bidirectional TVS installed at connector entry point to shunt fast transients to chassis ground. Use Value: Sub-5 ns response prevents bit errors; 107 V clamping protects ISO11898-compliant transceivers rated for 70 V absolute max. |
Use Scenario: Analog front-end of patient-connected ECG monitor with isolated sensor inputs susceptible to ESD discharge. IC Role / Device Role / Timing Role: TVS mounted directly at board edge connector to protect instrumentation amplifier inputs from ±8 kV contact ESD. Use Value: Meets IEC61000-4-2 Level 4 without degrading signal bandwidth - capacitance <100 pF at 0 V bias (per bidirectional half). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ60CA-E3/54 (Vishay) | Identical VWM (60 V), VC = 107 V @ 4.7 A, same DO-214AC package and RoHS termination. | Same IEC61000-4-2/4-4/4-5 compliance profile; minor variation in leakage (<1 µA vs. <5 µA at VWM). | Drop-in replacement where Vishay sourcing or dual-source strategy is required; identical footprint and electrical behavior. |
| 1.5SMC60CA (ON Semiconductor) | Higher VC = 110 V @ 4.5 A, same 500 W rating but slightly lower peak pulse current due to different VC/IPP ratio. | Marginally reduced clamping performance may impact systems with tight voltage headroom near 65 V IC limits. | Acceptable alternative if 3 V higher clamping is within system tolerance; verify thermal derating on same PCB layout. |
Compared with SMAJ60CE3/TR13, SMAJ60CA-E3/54 offers identical clamping and packaging for seamless second-source flexibility, while 1.5SMC60CA trades 3 V higher clamping for broader vendor availability - critical when designing for long-term supply continuity in medical or industrial programs.

FAQ
What does the "C" suffix in SMAJ60CE3/TR13 indicate?
The "C" suffix denotes bidirectional construction - meaning SMAJ60CE3/TR13 clamps transients equally in both polarities, unlike unidirectional variants (e.g., SMAJ60A). This eliminates polarity concerns during layout and supports AC-coupled or floating signal lines. The device has no cathode band marking, consistent with its symmetrical terminal behavior.
Is SMAJ60CE3/TR13 compliant with IEC61000-4-5 for lightning surge protection?
Yes, SMAJ60CE3/TR13 is validated for IEC61000-4-5 secondary lightning surge testing with 42 Ω source impedance at Class 1 level (up to 60 V VWM). It delivers 107 V clamping at 4.7 A under the 10/1000 µs waveform, ensuring downstream ICs remain within safe operating voltage limits during standardized surge events.
What is the maximum steady-state power dissipation for SMAJ60CE3/TR13?
SMAJ60CE3/TR13 dissipates up to 1.56 W at 25 °C ambient temperature and 5 W at 75 °C lead temperature when mounted on an FR4 PCB with the recommended footprint. Thermal performance depends on copper area and via count - derating is required above 75 °C lead temperature per the published derating curve.
Does SMAJ60CE3/TR13 require moisture-sensitive handling?
No - SMAJ60CE3/TR13 has IPC/JEDEC J-STD-020B moisture sensitivity level (MSL) 1, meaning it can be stored indefinitely at ambient conditions without dry packing or baking prior to reflow. This simplifies manufacturing logistics and reduces assembly risk compared to higher-MSL components.
How does the "TR13" suffix affect ordering and packaging of SMAJ60CE3/TR13?
The "TR13" suffix specifies tape-and-reel packaging: 2500 units per 13-inch reel, conforming to EIA-481-1-A standards. This format enables direct integration into automated SMT pick-and-place systems and supports just-in-time inventory replenishment for high-volume production runs.
