Product details
Overview
SMA5J5.0AHM3_A/I 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), 54.3 V clamping voltage at 9.2 A peak current, and operates from –55 °C to +150 °C junction temperature - used in automotive sensor power rail protection.
For engineers reviewing the SMA5J5.0AHM3_A/I datasheet, SMA5J5.0AHM3_A/I pinout, SMA5J5.0AHM3_A/I application, or SMA5J5.0AHM3_A/I equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification status, halogen-free RoHS compliance, 500 W surge rating, and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ns) to ESD and lightning-induced transients. Its low incremental surge resistance ensures stable clamping under high-current surges, while MSL Level 1 moisture sensitivity supports lead-free reflow up to 260 °C peak.
The device is rated for non-repetitive 8.3 ms half-sine forward surge current up to 40 A and exhibits 80 °C/W junction-to-ambient thermal resistance when mounted per recommended pad layout - critical for thermal management in compact automotive ECUs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - maximum continuous reverse operating voltage before clamping begins; defines safe DC bias margin for 5 V systems. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - guaranteed breakdown range ensures reliable turn-on without premature conduction during normal operation. |
| VC @ IPPM | 54.3 V at 9.2 A - clamping voltage limits downstream IC stress during 10/1000 µs surge events. |
| PPPM | 500 W - peak pulse power handling capacity determines survivability against IEC 61000-4-5 Level 4 surges. |
| TJ max | +150 °C - enables use in under-hood automotive environments without derating below ambient. |
| Package | SMA (DO-214AC) - surface-mount outline with 0.208" length and cathode band marking; compatible with standard pick-and-place feeders. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
| RoHS & Halogen-Free | Compliant per Vishay HM3 suffix - meets EU RoHS Directive 2011/65/EU and halogen-free material requirements (IEC 61249-2-21). |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with matte tin-plated leads, polarity indicated by cathode band at one end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point (unidirectional) | Connected to protected line side; reverse-biased during normal operation; conducts only during overvoltage events. |
| Cathode | Clamping reference node | Connected to ground or lower-potential rail; establishes clamping path to sink surge current away from sensitive circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Low profile SMA package | Height ≤ 0.090" (2.29 mm) - enables placement in space-constrained PCB layouts such as ADAS camera modules. |
| Glass passivated junction | Enhanced long-term stability and leakage control - maintains <800 µA ID at VWM across lifetime and temperature. |
| Fast response time | <1 ns turn-on - mitigates sub-microsecond ESD events (IEC 61000-4-2) before damage occurs to downstream MOSFETs or MCUs. |
| MSL Level 1 rating | Unlimited floor life at ≤30 °C/60% RH - eliminates bake requirements prior to reflow, reducing manufacturing cost and risk. |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics - includes HTGB, TC, and AC-H3TRB testing per AEC standard. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J5.0AHE3_A/I | Same electrical specs but RoHS-compliant commercial grade (non-halogen-free); no AEC-Q101 qualification. | Approved for industrial/commercial use only; not suitable for automotive production programs requiring halogen-free or AEC validation. | Select SMA5J5.0AHM3_A/I when halogen-free content and AEC-Q101 compliance are mandatory for Tier 1 automotive sourcing. |
| SMA6J5.0A-M3 | 600 W peak pulse power (vs. 500 W), same VWM/VBR/VC, identical SMA package; halogen-free RoHS compliant but not AEC-Q101 qualified. | Higher surge margin for legacy designs facing elevated IEC 61000-4-5 test levels; lacks automotive qualification documentation. | Choose SMA6J5.0A-M3 only if system-level surge testing exceeds 500 W requirements and AEC-Q101 is not required. |
Compared with SMA5J5.0AHE3_A/I and SMA6J5.0A-M3, the SMA5J5.0AHM3_A/I uniquely combines halogen-free construction, AEC-Q101 qualification, and 500 W surge capability in the SMA footprint - making it the sole option meeting full Tier 1 automotive BOM requirements for 5 V rail protection.

FAQ
What is the polarity configuration of the SMA5J5.0AHM3_A/I?
The SMA5J5.0AHM3_A/I is a unidirectional transient voltage suppressor diode. Its cathode is marked by a visible band on the SMA (DO-214AC) package body. During normal operation, it blocks reverse current up to 5.0 V; during overvoltage events, it conducts from anode to cathode to clamp the protected line to ground. This polarity must be observed in PCB layout to ensure correct protection directionality.
Does the SMA5J5.0AHM3_A/I meet AEC-Q101 requirements?
Yes, the SMA5J5.0AHM3_A/I is fully AEC-Q101 qualified. The "HM3" suffix denotes halogen-free, RoHS-compliant construction with AEC-Q101 validation, covering tests including high-temperature reverse bias (HTRB), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). This makes SMA5J5.0AHM3_A/I suitable for automotive powertrain and body electronics applications.
What is the maximum clamping voltage of the SMA5J5.0AHM3_A/I under surge conditions?
The SMA5J5.0AHM3_A/I has a maximum clamping voltage (VC) of 54.3 V at 9.2 A peak pulse current (IPPM), measured using the standardized 10/1000 µs double-exponential waveform. This value defines the upper voltage limit imposed on the protected circuit during worst-case transient events and is critical for ensuring downstream components remain within their absolute maximum ratings.
How does the SMA5J5.0AHM3_A/I differ from the SMA5J5.0A-E3/61 variant?
The SMA5J5.0AHM3_A/I differs from SMA5J5.0A-E3/61 in three key ways: it carries the HM3 suffix indicating halogen-free and AEC-Q101 qualification (E3 is RoHS-compliant commercial grade only); it uses tape-and-reel packaging code "I" for 7500-unit reels (E3/61 uses 1800-unit reels); and its revision marking "A/I" confirms latest production release with updated process controls and traceability.
What thermal considerations apply when mounting the SMA5J5.0AHM3_A/I?
When mounting the SMA5J5.0AHM3_A/I, use the recommended 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal to achieve the specified 80 °C/W junction-to-ambient thermal resistance. Smaller pads increase thermal impedance, causing higher junction temperatures during surge events and potential degradation. Thermal vias under pads further improve heat dissipation in multi-layer boards.
