Product details
Overview
SMA5J13HE3/5A from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on power and signal lines. It features 13 V standoff voltage (VWM), 21.5 V clamping voltage (VC) at 23.3 A peak pulse current (IPPM), 500 W peak pulse power (10/1000 µs), and AEC-Q101 qualification for automotive electronics.
For engineers reviewing the SMA5J13HE3/5A datasheet, SMA5J13HE3/5A pinout, SMA5J13HE3/5A application, or SMA5J13HE3/5A equivalent, this device is selected for robust overvoltage protection in DC power rails, automotive control modules, and industrial sensor interfaces where fast response (<1 ns), low clamping ratio, and high surge reliability are critical.
Technical Context
The SMA5J13HE3/5A operates as a unidirectional avalanche diode with glass-passivated junction, enabling stable breakdown behavior under repetitive transients. Its 14.4–15.9 V breakdown voltage (VBR at 1 mA) ensures precise triggering above nominal 13 V system rails while maintaining <1.0 µA reverse leakage at VWM.
Thermally, it exhibits 25 °C/W junction-to-lead thermal resistance and 80 °C/W junction-to-ambient (on 5 mm × 5 mm copper pads), supporting sustained operation up to 150 °C junction temperature. The device meets MSL Level 1 and JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before conduction begins |
| VBR (min/max) | 14.4 V / 15.9 V - Breakdown occurs within this range at 1 mA test current, ensuring reliable turn-on margin |
| VC @ IPPM | 21.5 V - Clamped voltage during 23.3 A 10/1000 µs surge, limiting downstream stress |
| PPPM | 500 W - Peak surge power handling capability per single transient event |
| IPPM | 23.3 A - Maximum non-repetitive surge current supported with defined waveform |
| TJ max | 150 °C - Maximum allowable junction temperature for long-term reliability |
| RθJL | 25 °C/W - Low thermal resistance path from junction to lead enables efficient heat dissipation |
Pinout & Package

|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Unidirectional TVS placed between power input and ground to clamp surges before they reach LDOs or microcontrollers. Use Value: With 21.5 V clamping at 23.3 A and 500 W rating, SMA5J13HE3/5A prevents damage to downstream 13.5 V-rated components during 35 V/100 ms load dump events. | Use Scenario: Safeguarding analog sensor outputs (e.g., pressure, temperature) in factory automation systems exposed to ESD and inductive switching noise. IC Role / Device Role / Timing Role: TVS mounted at connector interface to shunt fast transients before entering op-amp front-end or ADC input stage. Use Value: Sub-1 ns response time and 1.0 µA leakage at 13 V ensure signal integrity remains uncompromised during normal operation while suppressing ±15 kV contact ESD per IEC 61000-4-2. |
| DC Power Supply Input Protection | Telecom Line Card Surge Suppression |
Use Scenario: Input-stage protection for 12 V wall adapters and PoE-powered devices subject to lightning-induced surges. IC Role / Device Role / Timing Role: Primary surge clamp on DC input rail upstream of filtering and regulation circuitry. Use Value: 500 W peak power rating and 25 °C/W junction-to-lead thermal resistance allow repeated surge handling without thermal runaway in compact PCB layouts. | Use Scenario: Secondary-level protection on telecom line cards interfacing with external wiring susceptible to induced surges. IC Role / Device Role / Timing Role: Unidirectional TVS used in conjunction with gas discharge tubes (GDTs) for coordinated multi-stage protection. Use Value: Precise 14.4–15.9 V breakdown window enables clean coordination with upstream GDTs while maintaining low clamping to protect downstream PHY ICs rated for ≤24 V absolute maximum. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13A-E3/5A | Same electrical specs but commercial-grade (non-AEC-Q101); no JESD201 Class 2 whisker testing | Not qualified for automotive or harsh-environment use; suitable for consumer or industrial non-automotive designs | Select when AEC-Q101 qualification is not required and cost optimization is prioritized |
| SMC5J13AHE3/5A | Same VWM/VC but in larger DO-214AB (SMC) package; higher IFSM (100 A vs. 40 A) and lower RθJA (40 °C/W) | Better thermal performance and surge endurance; requires larger PCB footprint | Select when higher single-pulse surge margin or improved thermal derating is needed in space-tolerant designs |
Compared with SMA5J13A-E3/5A, the SMA5J13HE3/5A adds automotive qualification and enhanced whisker resistance; compared with SMC5J13AHE3/5A, it trades off surge robustness and thermal capacity for smaller DO-214AC footprint-making SMA5J13HE3/5A optimal for space-constrained AEC-Q101-compliant applications.

FAQ
What is the clamping voltage of the SMA5J13HE3/5A under maximum surge conditions?
The SMA5J13HE3/5A has a maximum clamping voltage (VC) of 21.5 V when subjected to its rated peak pulse current of 23.3 A using the standardized 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and ensures predictable voltage limiting during transient events. The SMA5J13HE3/5A maintains this clamping performance across its specified operating temperature range and is validated per AEC-Q101 stress tests.
Is the SMA5J13HE3/5A suitable for automotive applications?
Yes, the SMA5J13HE3/5A is AEC-Q101 qualified and explicitly rated for automotive use. Its HE3 suffix denotes RoHS compliance and JESD201 Class 2 whisker resistance, and it meets MSL Level 1 for lead-free reflow. The SMA5J13HE3/5A is designed for under-hood and body-control module applications where reliability under thermal cycling, vibration, and load-dump conditions is essential.
What is the difference between SMA5J13HE3/5A and SMA5J13A-E3/5A?
The SMA5J13HE3/5A is AEC-Q101 qualified and passes JESD201 Class 2 whisker testing, whereas the SMA5J13A-E3/5A is commercial-grade without automotive qualification. Both share identical electrical parameters (VWM, VBR, VC, PPPM), but only the SMA5J13HE3/5A is approved for automotive production. The HE3 suffix also indicates enhanced process controls for long-term reliability in harsh environments.
Does the SMA5J13HE3/5A have polarity marking, and how is it oriented on the PCB?
Yes, the SMA5J13HE3/5A is unidirectional and features a cathode band marking on the package body. During PCB layout, the banded end must be connected to ground (or the lower-potential rail), while the anode connects to the line being protected. Incorrect orientation will prevent proper clamping during reverse-polarity transients and may cause failure under surge conditions. The DO-214AC (SMA) outline drawing confirms band position relative to lead geometry.
What is the thermal resistance specification for the SMA5J13HE3/5A, and how does it affect layout?
The SMA5J13HE3/5A has a typical junction-to-lead thermal resistance (RθJL) of 25 °C/W and junction-to-ambient (RθJA) of 80 °C/W when mounted on 5.0 mm × 5.0 mm copper pads per terminal. To maintain safe operating temperature under repeated surges, PCB layout must provide adequate copper area and thermal vias-especially under the leads-to leverage the low RθJL. The SMA5J13HE3/5A's thermal performance is validated per JEDEC standards and included in its AEC-Q101 qualification report.
