Product details
Overview
SMA5J5.0AHE3_A/H from Vishay General Semiconductor is a unidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, rated for 5.0 V stand-off voltage (VWM), 6.4–7.07 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and 54.3 V clamping voltage at 9.2 A peak pulse current. It protects MOSFETs, ICs, and sensor signal lines against inductive switching transients in automotive and industrial power electronics.
For engineers reviewing the SMA5J5.0AHE3_A/H datasheet, SMA5J5.0AHE3_A/H pinout, SMA5J5.0AHE3_A/H application, or SMA5J5.0AHE3_A/H equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 500 W surge capability with 10/1000 µs waveform, low incremental surge resistance, and RoHS-compliant matte tin-plated leads solderable per J-STD-002.
Technical Context
This TVS diode operates as a clamping device in parallel with sensitive circuit nodes, conducting only when reverse voltage exceeds VBR to limit transient energy. Its glass-passivated junction ensures stable leakage (<800 µA at VWM) and fast response time (<1 ns), critical for protecting low-voltage logic interfaces.
Designed for surface-mount automated placement, it features MSL Level 1 moisture sensitivity and thermal resistance of 80 °C/W (junction-to-ambient) on standard 5.0 mm × 5.0 mm copper pads. The cathode band denotes polarity, and its DO-214AC outline supports high-power density layouts without derating penalties below 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe operating margin for 5 V rail protection. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - Confirmed breakdown threshold range ensures reliable turn-on during ESD or load-dump events. |
| VC @ IPPM | 54.3 V at 9.2 A - Clamped voltage under 10/1000 µs surge; limits stress on downstream 5 V logic components. |
| PPPM | 500 W - Peak pulse power handling capacity determines survivability against IEC 61000-4-5 Level 4 surges. |
| TJ max | +150 °C - Maximum junction temperature enables operation in under-hood automotive environments. |
| Polarity | Unidirectional - Requires correct orientation relative to protected circuit; cathode band marks terminal for PCB layout verification. |
| Package | SMA (DO-214AC) - Standardized surface-mount footprint with 2.54 mm lead pitch; compatible with reflow profiles up to 260 °C peak. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, UL 94 V-0 rated, dimensions 4.93 mm × 3.99 mm × 2.29 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Low-side reference node | Connected to ground or lowest potential point in protected circuit; forms return path during clamping. |
| Cathode (banded end) | High-side transient input | Connected to line being protected (e.g., 5 V supply rail or sensor output); conducts surge current to ground when V > VBR. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards. |
| Glass passivated junction | Ensures stable VBR tolerance and low leakage drift over lifetime; eliminates risk of metallization corrosion in humid environments. |
| MSL Level 1 rating | Allows unlimited floor life and compatibility with standard SMT reflow processes without baking preconditioning. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast transients; improves clamping precision for sub-100 ns ESD pulses. |
| RoHS-compliant & halogen-free option available | Base P/NHE3 meets RoHS; HM3 variant adds halogen-free compliance for stringent environmental compliance programs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0A-E3/61 | Same electrical specs and SMA package; RoHS-compliant but not AEC-Q101 qualified. | Limited to commercial/industrial use; unsuitable for automotive under-hood deployment. | Select when cost-sensitive non-automotive designs require identical clamping performance without qualification overhead. |
| SMA6J5.0AHE3_A/H | 600 W PPPM rating, same VWM/VBR, identical AEC-Q101 qualification and packaging. | Higher surge margin for systems subject to repetitive transients or extended test requirements (e.g., ISO 7637-2 Pulse 5a). | Choose when design margin requires ≥600 W peak power handling while retaining drop-in compatibility and automotive qualification. |
Compared with SMA5J5.0AHE3_A/H, SMA5J5.0A-E3/61 lacks automotive qualification but matches all electrical parameters, whereas SMA6J5.0AHE3_A/H delivers 20 % higher surge power in the same footprint-enabling robustness upgrades without layout change.

FAQ
What is the maximum clamping voltage of the SMA5J5.0AHE3_A/H under a 10/1000 µs surge?
The SMA5J5.0AHE3_A/H clamps to a maximum of 54.3 V at 9.2 A peak pulse current under a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and verified in the Vishay datasheet revision 09-Jan-2024. The clamping voltage directly determines the stress imposed on downstream 5 V logic devices during surge events, making it a critical parameter for interface protection design using the SMA5J5.0AHE3_A/H.
Is the SMA5J5.0AHE3_A/H suitable for automotive applications?
Yes, the SMA5J5.0AHE3_A/H is AEC-Q101 qualified, with testing covering temperature cycling, high-temperature operating life, and mechanical shock per JESD22 standards. Its operating junction temperature range of -55 °C to +150 °C and MSL Level 1 rating confirm suitability for under-hood and transmission-control module applications. The "HE3" suffix explicitly denotes AEC-Q101 qualification, distinguishing it from commercial variants like SMA5J5.0A-E3/61.
What does the "_A/H" suffix mean in SMA5J5.0AHE3_A/H?
The "_A/H" suffix in SMA5J5.0AHE3_A/H indicates the revision code ("A") and tape-and-reel packaging configuration ("H" = 7-inch diameter reel, 1800 units per reel). This ordering code aligns with Vishay's documented delivery mode structure and confirms the part ships in standard SMT-compatible packaging with RoHS-compliant matte tin leads. It does not affect electrical characteristics or qualification status of the SMA5J5.0AHE3_A/H.
How does the SMA5J5.0AHE3_A/H differ from bidirectional TVS diodes like SMA5J5.0CA?
The SMA5J5.0AHE3_A/H is unidirectional and features a cathode band for polarity identification, while SMA5J5.0CA is bidirectional with no marking and symmetrical clamping in both directions. Electrically, SMA5J5.0CA has a higher maximum VBR (7.25 V) and double the ID limit at low VWM. The SMA5J5.0AHE3_A/H must be oriented correctly in-circuit, whereas SMA5J5.0CA can be placed without regard to direction-making them functionally distinct despite shared package and power rating.
What is the thermal resistance of the SMA5J5.0AHE3_A/H, and how does it impact layout?
The SMA5J5.0AHE3_A/H has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout per Vishay's DO-214AC outline drawing. To maintain safe junction temperatures during repeated surges, PCB layout must allocate adequate copper area and avoid thermal bottlenecks-otherwise, the SMA5J5.0AHE3_A/H may exceed its +150 °C TJ max under sustained stress.
