Product details
Overview
SMAJ6.0CE3/TR13 from Microsemi is a bidirectional surface-mount transient voltage suppressor (TVS) designed for primary and secondary lightning surge protection, ESD/EFT immunity per IEC61000-4-2/4-4, and inductive switching transient suppression in power rails and signal lines. It features 6.0 V reverse standoff voltage (VWM), 6.67 V minimum breakdown voltage (VBR), 11.4 V maximum clamping voltage (VC) at 43.9 A peak pulse current, and 500 W peak pulse power rating at 10/1000 µs waveform.
For engineers reviewing the SMAJ6.0CE3/TR13 datasheet, SMAJ6.0CE3/TR13 pinout, SMAJ6.0CE3/TR13 application, or SMAJ6.0CE3/TR13 equivalent, this device is selected for robust overvoltage protection in automotive body electronics, industrial I/O interfaces, telecom line cards, and DC power input stages where fast response (<5 ns), low clamping, and RoHS-compliant surface-mount reliability are required.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, enabling protection of AC-coupled or floating signal paths without polarity constraints. Its silicon avalanche structure delivers sub-nanosecond response to transients, with clamping action triggered when reverse or forward voltage exceeds VBR = 6.67 V @ IBR = 10 mA.
Thermal performance is defined by 15 °C/W junction-to-lead resistance and 80 °C/W junction-to-ambient (FR4, 1 oz Cu), supporting continuous dissipation of 1.56 W at 25 °C ambient or 5 W at 75 °C lead temperature. The DO-214AC (SMA) package ensures mechanical robustness and solderability per MIL-STD-750 Method 2026.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before leakage exceeds 800 µA; sets upper limit for protected circuit's normal operating range. |
| VBR min | 6.67 V @ 10 mA - Minimum voltage at which avalanche conduction begins; defines turn-on threshold under standardized test conditions. |
| VC | 11.4 V @ IPP = 43.9 A - Clamped voltage during 10/1000 µs surge; determines maximum stress imposed on downstream components. |
| PPP | 500 W - Peak pulse power handling capability; enables protection against high-energy transients like IEC61000-4-5 Class 4 (12 Ω source). |
| IPP | 43.9 A - Peak surge current supported at rated clamping voltage; directly correlates with system-level surge immunity level. |
| Response time | <5 ns - Bidirectional clamping delay; ensures suppression before sensitive logic or analog circuitry sustains damage. |
| Package | DO-214AC (SMA) - Standardized surface-mount outline with wide leads for thermal dissipation and mechanical stability on PCBs. |
Pinout & Package
DO-214AC (SMA) package: molded thermosetting epoxy case meeting UL94V-0; void-free construction; C-bend (modified J-bend) leads with RoHS-compliant matte-tin plating; cathode marking omitted on bidirectional variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional terminal pair | No polarity designation; either terminal serves as anode or cathode depending on transient polarity; enables AC or floating rail protection. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional architecture | Enables single-device protection of differential signals, AC lines, or ungrounded buses without external polarity management. |
| RoHS-compliant "e3" suffix | Meets EU Directive 2011/65/EU with annealed matte-tin plating; eliminates lead content while maintaining solderability and reliability. |
| Tape-and-reel packaging (TR13) | 2500 units per 13-inch reel per EIA-481-1-A; supports automated SMT placement with standard feeder compatibility. |
| IEC61000-4-5 Class 4 compliance | Validated for secondary lightning surges with 12 Ω source impedance up to 43.9 A peak current; meets industrial port protection requirements. |
| Moisture sensitivity Level 1 | No dry-pack or baking required prior to reflow; simplifies manufacturing flow and reduces handling risk. |
Applications
| Automotive Body Control Module (BCM) Power Input | Industrial RS-485 Transceiver Protection |
|---|---|
Use Scenario: 12 V battery-fed BCM power rail exposed to load dump and jump-start transients. IC Role / Device Role / Timing Role: Primary overvoltage clamp placed between VIN and GND, upstream of DC/DC converter input. Use Value: Limits transient voltage to ≤11.4 V, preventing damage to 16 V-rated input capacitors and enabling compliance with ISO 7637-2 Pulse 5a. |
Use Scenario: RS-485 data lines in factory automation systems subject to ESD and induced RF coupling. IC Role / Device Role / Timing Role: Bidirectional TVS connected across differential pair (A–B) and to ground, suppressing common-mode and differential surges. Use Value: Clamps ±15 kV ESD events (IEC61000-4-2) within <5 ns, preserving signal integrity and avoiding receiver latch-up. |
| Telecom DSL Line Card Surge Protection | DC Power Supply Input Stage |
Use Scenario: POTS/DSL line interface exposed to lightning-induced surges on twisted-pair copper lines. IC Role / Device Role / Timing Role: Secondary protection device after gas discharge tube (GDT), shunting residual energy to ground. Use Value: Handles 43.9 A peak current at 11.4 V clamping, ensuring GDT follow-on current is safely diverted per IEC61000-4-5 Class 2 (42 Ω source). |
Use Scenario: 5–12 V DC input stage of embedded power supply subjected to inductive switching noise and hot-plug transients. IC Role / Device Role / Timing Role: Low-capacitance TVS placed at connector entry point to absorb fast-rising edge transients before bulk capacitance. Use Value: Provides 500 W surge rating with 6.0 V standoff, allowing stable operation during nominal 5.5 V–12 V input while blocking >11.4 V spikes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A | Unidirectional variant; same VWM, VBR, VC, and PPP; includes cathode band marking. | Requires known polarity in circuit; unsuitable for AC or floating nodes. | Select SMAJ6.0A only when protecting DC rails with fixed polarity and space-constrained layouts needing identical footprint. |
| SMBJ6.0CA | Same bidirectional function but in DO-214AA (SMB) package; 600 W PPP; VC = 10.3 V @ 58.5 A. | Higher surge rating and lower clamping, but larger footprint and higher thermal resistance (20 °C/W j–l). | Choose SMBJ6.0CA when system-level surge tests exceed 43.9 A or when lower clamping voltage is prioritized over board area. |
Compared with SMAJ6.0CE3/TR13, SMAJ6.0A lacks bidirectional symmetry and requires polarity-aware layout, while SMBJ6.0CA offers higher surge margin and tighter clamping but consumes more PCB area and dissipates heat less efficiently-making SMAJ6.0CE3/TR13 optimal for compact, polarity-agnostic 500 W protection.

FAQ
What does the "CE3/TR13" suffix mean in SMAJ6.0CE3/TR13?
The "C" denotes bidirectional configuration, "E3" indicates RoHS-compliant matte-tin plating per JEDEC J-STD-020B Level 1 moisture sensitivity, and "TR13" specifies tape-and-reel packaging with 2500 units per 13-inch reel. These suffixes define critical electrical, environmental, and assembly attributes of the SMAJ6.0CE3/TR13 device.
Is SMAJ6.0CE3/TR13 suitable for IEC61000-4-5 compliance testing?
Yes, SMAJ6.0CE3/TR13 is validated for IEC61000-4-5 secondary lightning protection up to Class 4 (12 Ω source impedance) with 43.9 A peak pulse current and 11.4 V clamping voltage. Its bidirectional design and 500 W rating make it appropriate for Ethernet, RS-485, and DC power port testing per this standard.
How does SMAJ6.0CE3/TR13 differ from unidirectional SMAJ6.0A?
SMAJ6.0CE3/TR13 provides symmetrical clamping for both positive and negative transients, eliminating polarity constraints in AC or floating circuits. In contrast, SMAJ6.0A is unidirectional with a cathode band, limiting use to DC rails with known polarity-and cannot protect bidirectional signals without additional components.
What is the maximum steady-state power dissipation of SMAJ6.0CE3/TR13?
SMAJ6.0CE3/TR13 dissipates 1.56 W at 25 °C ambient temperature and 5 W at 75 °C lead temperature when mounted on FR4 with 1 oz copper and the recommended pad layout. This thermal performance is enabled by its DO-214AC package and 15 °C/W junction-to-lead thermal resistance.
Can SMAJ6.0CE3/TR13 be used in place of SMAJ6.0CA?
Yes-SMAJ6.0CE3/TR13 and SMAJ6.0CA share identical electrical specifications (VWM, VBR, VC, PPP) and bidirectional functionality; the "E3" suffix simply confirms RoHS compliance, while "CA" is the legacy non-RoHS designation. Both are drop-in replacements in existing designs meeting JEDEC moisture and soldering requirements.
