Product details
Overview
SMAJ13AHE3/61 from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA test current, and clamps up to 21.5 V at 18.6 A peak pulse current (IPPM) under 10/1000 μs waveform.
For engineers reviewing the SMAJ13AHE3/61 datasheet, SMAJ13AHE3/61 pinout, SMAJ13AHE3/61 application, or SMAJ13AHE3/61 equivalent, key selection considerations include its AEC-Q101 qualification for automotive use, 400 W peak pulse power rating (derated to 300 W above 78 V), low incremental surge resistance, and compatibility with automated SMT placement on PCBs requiring robust ESD and surge immunity.
Technical Context
The SMAJ13AHE3/61 operates as a clamping-type unidirectional TVS diode, leveraging an avalanche breakdown mechanism to limit transient overvoltages across protected lines. Its glass-passivated junction ensures stable breakdown characteristics and fast response time (<1 ns), while the SMA package provides thermal resistance of 120 °C/W (junction-to-ambient) and 30 °C/W (junction-to-lead).
Designed for single-polarity protection, it conducts only during reverse-biased overvoltage events - forward conduction is limited to 3.5 V at 25 A (IF). The device meets MSL Level 1 per J-STD-020, supports lead-free reflow up to 260 °C peak, and is rated for operation from –55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin below breakdown. |
| VBR (Breakdown Voltage) | 14.4–15.9 V at 1 mA - Confirmed avalanche threshold range; ensures reliable triggering during transients without premature conduction. |
| VC (Clamping Voltage) | 21.5 V at IPPM = 18.6 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines maximum stress on downstream components. |
| PPPM (Peak Pulse Power) | 400 W (10/1000 μs) - Transient energy absorption capacity; derates to 300 W above 78 V per spec. |
| ID (Reverse Leakage) | 1.0 μA max at VWM - Low leakage preserves signal integrity and minimizes standby power loss in high-impedance circuits. |
| TJ max. | +150 °C - Enables deployment in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A-E3/61 | Commercial-grade version; not AEC-Q101 qualified; identical electrical specs and package. | Limited to non-automotive industrial or consumer applications where automotive qualification is not required. | Select SMAJ13AHE3/61 when automotive-grade reliability and extended temperature validation are mandatory. |
| SMBJ13AHE3/61 | Same VWM/VBR/VC specs but in larger SMB (DO-214AA) package; higher thermal mass (RθJA = 85 °C/W vs. 120 °C/W). | Better suited for higher average power dissipation scenarios or less dense PCB layouts where footprint allows. | Choose SMBJ13AHE3/61 if board layout permits larger footprint and thermal performance under repetitive surge conditions is prioritized. |

FAQ
What is the clamping voltage of SMAJ13AHE3/61 at its rated peak pulse current?
The SMAJ13AHE3/61 has a maximum clamping voltage (VC) of 21.5 V at 18.6 A peak pulse current (IPPM) under the standard 10/1000 μs waveform. This value is measured per JEDEC test conditions and defines the upper voltage limit imposed on protected circuitry during transient events. The SMAJ13AHE3/61 maintains this clamping performance across its full operating temperature range (–55 °C to +150 °C), ensuring predictable protection in demanding environments.
Is SMAJ13AHE3/61 suitable for automotive applications?
Yes, SMAJ13AHE3/61 is AEC-Q101 qualified and specifically intended for automotive use. Its qualification covers temperature cycling, high-temperature reverse bias (HTRB), and ESD testing per AEC standards. The device is commonly deployed in body control modules, infotainment interfaces, and ADAS sensor signal conditioning circuits where sustained reliability under vibration, thermal stress, and electrical transients is required. SMAJ13AHE3/61 meets ISO 7637-2 and ISO 16750-2 surge immunity requirements when applied per Vishay's recommended layout guidelines.
How does the SMAJ13AHE3/61 differ from the SMAJ13A-E3/61?
The SMAJ13AHE3/61 and SMAJ13A-E3/61 share identical electrical specifications - same VWM (13 V), VBR (14.4–15.9 V), VC (21.5 V), and PPPM (400 W). The sole difference is qualification: SMAJ13AHE3/61 carries AEC-Q101 certification for automotive use, while SMAJ13A-E3/61 is commercial-grade only. Both use the same SMA (DO-214AC) package and RoHS-compliant matte tin plating. SMAJ13AHE3/61 is the appropriate choice when automotive qualification is mandated by program requirements or safety standards.
What is the maximum reverse leakage current for SMAJ13AHE3/61 at its stand-off voltage?
The SMAJ13AHE3/61 exhibits a maximum reverse leakage current (ID) of 1.0 μA at its 13 V stand-off voltage (VWM), measured at 25 °C. This low leakage ensures minimal impact on high-impedance signal paths and battery-powered circuits. Leakage remains within specification across the full operating temperature range, supporting stable performance in precision analog front-ends and always-on sensor interfaces where quiescent current budget is constrained.
Can SMAJ13AHE3/61 be used in bidirectional protection configurations?
No, SMAJ13AHE3/61 is a unidirectional TVS diode and is not suitable for bidirectional protection. Its cathode band indicates polarity, and it conducts only during reverse-biased overvoltage events. For bidirectional applications - such as AC signal lines or differential buses like RS-485 - a part with "CA" suffix (e.g., SMAJ13CAHE3/61) must be selected. Using SMAJ13AHE3/61 in bidirectional mode risks forward conduction during normal signal swings and failure to clamp positive transients.
