Product details
Overview
SMAJ6.0AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for primary overvoltage protection of sensitive electronics. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR) at 10 mA, and clamps transients to ≤10.3 V at 38.8 A peak pulse current (IPPM) under 10/1000 μs waveform - ideal for safeguarding power rails and I/O lines in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the SMAJ6.0AHE3/61 datasheet, SMAJ6.0AHE3/61 pinout, SMAJ6.0AHE3/61 application, or SMAJ6.0AHE3/61 equivalent, key selection criteria include its AEC-Q101 qualification, 400 W peak pulse power rating, low clamping ratio (VC/VBR ≈ 1.5), and SMA (DO-214AC) package compatibility with automated SMT assembly.
Technical Context
This TVS diode operates as a voltage-clamping device in parallel with protected circuitry, conducting only when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), enabling effective suppression of ESD (IEC 61000-4-2), EFT (IEC 61000-4-4), and lightning-induced surges (IEC 61000-4-5).
The SMAJ6.0AHE3/61 is rated for 40 A non-repetitive forward surge current (IFSM), supports -55 °C to +150 °C operating junction temperature, and exhibits a low 0.059 %/°C temperature coefficient of VBR - critical for stable clamping across automotive thermal cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 6.0 V - maximum continuous reverse working voltage before significant leakage; defines safe operating margin below VBR. |
| VBR (Breakdown Voltage) | 6.67–7.37 V at 10 mA - precise voltage threshold where device transitions into avalanche conduction. |
| VC (Clamping Voltage) | ≤10.3 V at IPPM = 38.8 A - maximum voltage seen by protected circuit during worst-case 10/1000 μs surge. |
| PPPM (Peak Pulse Power) | 400 W - energy-handling capability for 10/1000 μs transients; derates to 300 W above 78 V. |
| ID (Reverse Leakage) | ≤800 μA at VWM - low off-state current minimizes standby power loss and avoids false triggering. |
| TJ max. | +150 °C - enables use in under-hood automotive environments and high-temperature industrial enclosures. |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per AEC standard. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002. Cathode indicated by band on body; anode is unmarked end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Transient current sink | Connected to protected line; conducts surge current to ground when Vreverse > VBR. |
| Anode (unbanded end) | Reference node | Typically tied to system ground or lower-potential rail; completes clamping path during overvoltage events. |
Key Features
| Feature | Design Value |
|---|---|
| 400 W peak pulse power (10/1000 μs) | Enables robust protection against ISO 7637-2 Load Dump and IEC 61000-4-5 surge waveforms without derating. |
| AEC-Q101 qualified (HE3 suffix) | Validated for automotive applications including engine control, ADAS sensors, and infotainment power supplies. |
| Low clamping ratio (VC/VBR ≈ 1.5) | Minimizes voltage overshoot during clamping, reducing stress on downstream ICs like microcontrollers and CAN transceivers. |
| MSL Level 1 (260 °C reflow compatible) | Supports lead-free reflow soldering without moisture sensitivity concerns or baking requirements. |
| Glass passivated junction | Ensures long-term stability of VBR and low leakage drift over temperature and lifetime. |
Applications
| Automotive Power Rail Protection | Industrial Sensor Interface Protection |
|---|---|
Use Scenario: Protecting 5 V/12 V power inputs in engine control modules against load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power rail and chassis ground to clamp positive transients. Use Value: Limits voltage to ≤10.3 V during 38.8 A surges, preventing latch-up or damage to MCU power domains. |
Use Scenario: Shielding analog output lines (e.g., 4–20 mA current loop) of pressure/temperature sensors from ESD and cable discharge events. IC Role / Device Role / Timing Role: TVS connected across signal and return lines to shunt fast transients before reaching precision amplifier inputs. Use Value: Sub-1 ns response ensures clamping occurs before sensor signal conditioning circuitry is exposed to damaging voltages. |
| Consumer USB Port ESD Protection | Telecom Line Card Surge Suppression |
Use Scenario: Safeguarding USB VBUS and D+/D− lines in portable chargers and docking stations against contact ESD (±8 kV air, ±15 kV contact). IC Role / Device Role / Timing Role: Discrete TVS array configured per-line to absorb ESD energy before it reaches USB PHY ICs. Use Value: Low 800 μA leakage at 6.0 V prevents interference with USB enumeration and maintains bus integrity. |
Use Scenario: Front-end protection of Ethernet PHY or RS-485 transceivers on telecom base station line cards exposed to lightning-induced surges. IC Role / Device Role / Timing Role: Primary clamping device in multi-stage protection scheme, absorbing bulk surge energy before secondary MOV/GDT stages. Use Value: 400 W rating handles repetitive 10/1000 μs surges up to 300 V common-mode, extending system MTBF. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ6.0A-E3/61 | Commercial-grade (non-AEC-Q101); identical electrical specs but no automotive qualification testing. | Not suitable for automotive production; acceptable for industrial or consumer prototypes. | Select SMAJ6.0AHE3/61 when AEC-Q101 compliance is required for OEM automotive programs. |
| SMBJ6.0AHE3/61 | Same VWM/VBR/VC but higher 600 W PPPM rating and SMB (DO-214AA) package (larger footprint, higher thermal mass). | Better suited for higher-energy surges; requires PCB layout change due to larger pad dimensions. | Choose SMBJ6.0AHE3/61 only if surge energy exceeds 400 W or thermal dissipation demands greater copper area. |
Compared with SMAJ6.0A-E3/61, the SMAJ6.0AHE3/61 adds AEC-Q101 validation for automotive use without altering clamping performance; versus SMBJ6.0AHE3/61, it trades 200 W pulse power headroom for space-constrained SMA footprint compatibility.

FAQ
What is the clamping voltage of the SMAJ6.0AHE3/61 at its rated peak pulse current?
The SMAJ6.0AHE3/61 has a maximum clamping voltage (VC) of 10.3 V at its rated peak pulse current (IPPM) of 38.8 A under the standardized 10/1000 μs waveform. This value is measured per JEDEC test conditions and guarantees that protected circuitry will not experience more than 10.3 V during such transient events, ensuring compatibility with 5 V logic and power domains.
Is the SMAJ6.0AHE3/61 suitable for automotive applications?
Yes, the SMAJ6.0AHE3/61 is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". It undergoes rigorous stress testing including temperature cycling, high-temperature reverse bias, and ESD verification - making it appropriate for under-hood and cabin-mounted automotive electronics such as body control modules and ADAS sensor power supplies.
How does the SMAJ6.0AHE3/61 differ from the SMAJ6.0A-E3/61?
The SMAJ6.0AHE3/61 and SMAJ6.0A-E3/61 share identical electrical parameters (VWM, VBR, VC, PPPM), but the HE3 variant includes full AEC-Q101 qualification and automotive-grade traceability. The E3 version is commercial-grade only and lacks automotive reliability validation - both use the same SMA (DO-214AC) package and RoHS-compliant matte tin plating.
What is the maximum operating junction temperature for the SMAJ6.0AHE3/61?
The SMAJ6.0AHE3/61 has a maximum operating junction temperature (TJ max.) of +150 °C, verified per Vishay's thermal characterization data. This allows reliable operation in high-ambient environments such as automotive engine compartments or sealed industrial enclosures, provided PCB copper pad layout meets the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) per terminal specification.
Does the SMAJ6.0AHE3/61 require special handling for moisture sensitivity?
No - the SMAJ6.0AHE3/61 is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and can be subjected to standard lead-free reflow profiles (peak 260 °C) without pre-baking. Its molding compound meets UL 94 V-0 flammability rating, and terminals comply with JESD 22-B102 whisker resistance Class 2.
