Product details
Overview
SMA6J6.0A-E3/5A from Vishay General Semiconductor is a unidirectional surface-mount TransZORB® transient voltage suppressor (TVS) diode designed for clamping inductive switching surges and lightning-induced transients on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.7–7.41 V breakdown voltage (VBR at 10 mA), 9.5 V maximum clamping voltage (VC) at 63.2 A (10/1000 μs), 600 W peak pulse power rating, and SMA (DO-214AC) package with matte tin-plated leads.
For engineers reviewing the SMA6J6.0A-E3/5A datasheet, SMA6J6.0A-E3/5A pinout, SMA6J6.0A-E3/5A application, or SMA6J6.0A-E3/5A equivalent, key selection criteria include clamping performance at 63.2 A IPP, thermal resistance (RθJA = 120 °C/W), unidirectional polarity, RoHS-compliant industrial-grade construction, and compatibility with automated SMT placement on PCBs with 5.0 mm × 5.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamped crowbar device triggered above its breakdown threshold, providing low-impedance shunt protection during transient events. Its dynamic resistance (RD = 0.033 Ω) and tight VBR tolerance (6.7–7.41 V) ensure predictable clamping onset and minimal overshoot under standardized 10/1000 μs and 8/20 μs surge waveforms.
Designed for surface-mount integration, it leverages the SMA (DO-214AC) package's MSL Level 1 rating (260 °C reflow peak), UL 94 V-0 molding compound, and cathode band polarity marking. Thermal performance is specified with RθJA = 120 °C/W and RθJL = 25 °C/W, supporting operation up to TJ = 150 °C with derating above TA = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 6.0 V - Maximum continuous reverse operating voltage before leakage exceeds 10 µA; defines safe DC bias margin. |
| VBR (min/max) | 6.7 V / 7.41 V at IT = 10 mA - Confirmed breakdown range ensures reliable turn-on without premature conduction. |
| VC @ IPP | 9.5 V at 63.2 A (10/1000 μs) - Clamping voltage limits downstream IC/MOSFET stress during typical inductive load transients. |
| PPPM (10×1000 μs) | 600 W - Peak surge energy handling capacity under standard long-duration waveform per IEC 61000-4-5. |
| ID @ VWM | 600 µA max - Low leakage preserves power rail integrity and avoids false triggering in high-impedance circuits. |
| TJ max. | 150 °C - Enables use in industrial environments with elevated ambient temperatures and limited heatsinking. |
| RθJA | 120 °C/W - Thermal resistance value used to calculate junction temperature rise under steady-state PD = 4 W dissipation. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, unidirectional polarity, cathode denoted by color band. Matte tin-plated leads meet J-STD-002 and JESD 22-B102 solderability standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction or transient clamping | Connected to protected line (e.g., VCC or signal); must be routed with low-inductance trace to minimize clamping delay. |
| Cathode | Current exit terminal; marked by color band | Connected to ground reference plane; requires low-impedance return path to sustain clamping performance under high di/dt. |
Key Features
| Feature | Design Value |
|---|---|
| Unidirectional polarity | Enables precise clamping only on negative-going transients relative to cathode; prevents unintended conduction on positive excursions. |
| MSL Level 1 compliance | Supports single-reflow assembly without moisture sensitivity concerns; eliminates bake-out requirement prior to SMT placement. |
| UL 94 V-0 molding compound | Ensures flame-retardant encapsulation suitable for consumer, industrial, and telecom end equipment meeting safety certifications. |
| RoHS-compliant & industrial grade | E3 suffix confirms lead-free, halogen-free (except exempted), and qualified for extended temperature operation (-55 °C to +150 °C). |
| Low dynamic resistance (RD) | 0.033 Ω enables rapid voltage clamping with minimal overshoot, critical for protecting fast-switching MOSFETs and logic ICs. |
Applications
| Industrial Motor Drive Protection | Automotive Body Control Module (BCM) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA6J6.0A-E3/61 | Same electrical specs; differs only in packaging: 7″ tape/reel (1800 pcs) vs. 13″ tape/reel (7500 pcs) for SMA6J6.0A-E3/5A | Optimized for low-volume prototyping or small-batch production due to smaller reel size and lower base quantity | Select SMA6J6.0A-E3/61 when demand volume or SMT feeder constraints favor smaller reels; identical performance and qualification. |
| SMC6J6.0A-E3/57T | Higher power rating: 1500 W (10/1000 μs), larger SMC (DO-214AB) package, RθJA = 40 °C/W, same VWM/VBR/VC specs | Used where higher surge repetition rate or sustained power dissipation is required, e.g., heavy-duty industrial controls | Choose SMC6J6.0A-E3/57T only if system-level testing confirms need for >600 W single-pulse capability or improved thermal management; not drop-in compatible due to footprint change. |
Compared with SMA6J6.0A-E3/61, the SMA6J6.0A-E3/5A offers higher volume efficiency per reel but identical electrical behavior; versus SMC6J6.0A-E3/57T, it trades surge capacity and thermal performance for compact SMA footprint-critical for space-constrained consumer and telecom PCBs.

FAQ
What is the maximum clamping voltage of the SMA6J6.0A-E3/5A under a 10/1000 μs surge?
The SMA6J6.0A-E3/5A has a maximum clamping voltage (VC) of 9.5 V when subjected to a 63.2 A peak pulse current with a 10/1000 μs waveform. This value is measured at TA = 25 °C on PCBs with 5.0 mm × 5.0 mm copper pads per terminal and defines the upper voltage limit imposed on protected circuitry during standardized surge events.
Is the SMA6J6.0A-E3/5A suitable for bidirectional transient protection?
No, the SMA6J6.0A-E3/5A is strictly unidirectional, as confirmed in the Vishay datasheet under FEATURES and ELECTRICAL CHARACTERISTICS. It clamps only reverse-biased transients (cathode positive relative to anode) and must not be used in AC or bipolar signal paths without additional circuitry; bidirectional variants like SMA6J6.0CA require separate selection.
What does the "E3/5A" suffix indicate in SMA6J6.0A-E3/5A?
The "E3" denotes RoHS-compliant, industrial-grade construction with matte tin-plated leads and JESD 201 Class 2 whisker resistance; "5A" specifies the packaging format: 13-inch diameter plastic tape and reel containing 7500 units, optimized for high-volume SMT production lines.
How does the thermal resistance of SMA6J6.0A-E3/5A affect its power handling capability?
With a typical junction-to-ambient thermal resistance (RθJA) of 120 °C/W, the SMA6J6.0A-E3/5A dissipates up to 4 W continuously at TA = 50 °C. At higher ambient temperatures, derating per Figure 2 in the datasheet applies-e.g., at TA = 85 °C, usable PD drops to ~2.4 W-making pad layout and airflow critical for sustained operation.
Can SMA6J6.0A-E3/5A replace SMAJ6.0A in existing designs?
No direct replacement is guaranteed: SMAJ6.0A is a different family (lower PPPM = 400 W, higher VC ≈ 10.5 V) with distinct VBR (6.67–7.37 V) and thermal characteristics. While both use SMA packages, the SMA6J6.0A-E3/5A delivers 50% higher surge power and tighter clamping-substitution requires validation of clamping margin, leakage, and board-level thermal performance.
