Product details
Overview
SMA5J5.0AHE3/61 from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for primary overvoltage protection of DC power rails and signal lines. It features 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 µs), 9.2 V clamping voltage at 54.3 A peak current, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J5.0AHE3/61 datasheet, SMA5J5.0AHE3/61 pinout, SMA5J5.0AHE3/61 application, or SMA5J5.0AHE3/61 equivalent, this page delivers verified electrical parameters, thermal resistance (RθJA = 80 °C/W), polarity marking (cathode band), RoHS-compliant matte tin terminals, and MSL Level 1 reflow compatibility up to 260 °C.
Technical Context
This TVS diode operates as a unidirectional clamping device with avalanche breakdown behavior, triggered when reverse voltage exceeds VBR. Its glass-passivated junction ensures stable leakage (<800 µA at VWM) and fast response time (<1.0 ps), enabling suppression of ESD, lightning-induced surges, and inductive switching transients before downstream ICs are damaged.
Designed for surface-mount placement on 5.0 mm × 5.0 mm copper pads per terminal, it delivers 500 W surge handling under standardized 10/1000 µs waveform conditions. Thermal performance is defined by RθJL = 25 °C/W (junction-to-lead) and RθJA = 80 °C/W (junction-to-ambient), supporting operation from –55 °C to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - guaranteed avalanche initiation range for reliable threshold control |
| VC @ IPPM | 9.2 V at 54.3 A - clamped voltage during 500 W transient, limiting stress on protected circuitry |
| PPPM | 500 W (10/1000 µs) - standardized surge energy absorption capacity for industrial-grade immunity |
| ID @ VWM | <800 µA - low leakage preserves battery life and avoids false triggering in low-power systems |
| TJ max | +150 °C - enables under-hood automotive deployment without derating in high-ambient environments |
| RθJA | 80 °C/W - defines required PCB copper area for thermal management in continuous surge scenarios |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0A-E3/61 | Lower PPPM (400 W vs. 500 W); same VWM/VBR/VC; non-AEC-Q101 | Not qualified for automotive under-hood use; suitable for commercial-grade consumer/industrial designs | Select when cost sensitivity outweighs surge margin and AEC-Q101 compliance is not required |
| SMA6J5.0AHE3/61 | Higher PPPM (600 W); identical VWM/VBR/VC; same AEC-Q101 qualification and HE3 suffix | Provides 20 % higher surge margin for harsher environments (e.g., commercial vehicle alternator load dump) | Choose when system-level surge testing exceeds IEC 61000-4-5 Level 4 or requires extended lifetime under repetitive transients |
Compared with SMAJ5.0A-E3/61 and SMA6J5.0AHE3/61, the SMA5J5.0AHE3/61 delivers optimal balance of 500 W surge capability, AEC-Q101 qualification, and standard SMA footprint-making it ideal for cost-constrained automotive body electronics where 600 W headroom is unnecessary and 400 W is insufficient.

FAQ
What is the clamping voltage of the SMA5J5.0AHE3/61 under maximum surge conditions?
The SMA5J5.0AHE3/61 has a maximum clamping voltage (VC) of 9.2 V at 54.3 A peak pulse current, measured under standardized 10/1000 µs waveform conditions. This value ensures protected circuits-such as 5 V CAN transceivers or microcontrollers-remain within their absolute maximum voltage ratings during surge events. The SMA5J5.0AHE3/61 maintains this clamping performance across its full operating temperature range (–55 °C to +150 °C).
Is the SMA5J5.0AHE3/61 suitable for automotive applications?
Yes, the SMA5J5.0AHE3/61 is AEC-Q101 qualified and carries the HE3 suffix indicating RoHS-compliance and automotive-grade reliability. It is rated for junction temperatures up to +150 °C and meets MSL Level 1 reflow requirements-making it appropriate for under-hood and body-control module deployments. The SMA5J5.0AHE3/61 is explicitly validated for load dump, ESD, and inductive switching protection in automotive power networks.
What does the "HE3" suffix mean in SMA5J5.0AHE3/61?
The "HE3" suffix in SMA5J5.0AHE3/61 denotes RoHS-compliant construction with AEC-Q101 qualification, distinguishing it from commercial-grade variants (e.g., E3). It confirms compliance with automotive stress testing including temperature cycling, humidity bias, and surge endurance. The SMA5J5.0AHE3/61 also features matte tin-plated leads qualified per JESD 201 Class 2 whisker testing.
How does the SMA5J5.0AHE3/61 compare to bidirectional TVS diodes like SMA5J5.0CA?
The SMA5J5.0AHE3/61 is unidirectional and intended for DC rail protection where polarity is fixed (e.g., 5 V supply lines), while SMA5J5.0CA is bidirectional for AC or dual-polarity signal lines. The SMA5J5.0AHE3/61 offers lower leakage (<800 µA) and supports forward surge current (IFSM = 40 A), unlike bidirectional types. Its cathode band marking simplifies layout verification in unidirectional configurations.
What PCB layout guidance applies to the SMA5J5.0AHE3/61 for optimal thermal performance?
For optimal thermal dissipation, the SMA5J5.0AHE3/61 must be mounted on minimum 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, as specified in the Vishay datasheet. This pad size supports its RθJA of 80 °C/W and prevents junction overheating during repetitive 500 W surges. Avoid thermal relief spokes on pads; use solid copper pours connected to internal ground/power planes where possible. The SMA5J5.0AHE3/61 datasheet Fig. 2 provides derating curves above TA = 25 °C.
