Product details
Overview
SMA5J5.0CAHE3_A/H from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 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), clamping voltage of 9.2 V at 54.3 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J5.0CAHE3_A/H datasheet, SMA5J5.0CAHE3_A/H pinout, SMA5J5.0CAHE3_A/H application, or SMA5J5.0CAHE3_A/H equivalent, key selection criteria include bidirectional clamping capability, low clamping ratio (VC/VWM ≈ 1.84), MSL Level 1 moisture sensitivity, and RoHS-compliant + halogen-free AEC-Q101 qualification under HE3 suffix.
Technical Context
This bidirectional TVS operates symmetrically across both polarities, with identical electrical characteristics in forward and reverse directions per specification. Its glass-passivated junction ensures stable breakdown behavior and fast response time (<1 ns), while low incremental surge resistance enables effective energy diversion during transients induced by inductive switching or ESD events.
The device is rated for TJ = –55 °C to +150 °C operation and mounted on 5.0 mm × 5.0 mm copper pads per test condition. Thermal resistance is 80 °C/W (junction-to-ambient) and 25 °C/W (junction-to-lead), supporting reliable power dissipation in compact PCB layouts without active cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 5.0 V - Maximum continuous reverse operating voltage before clamping begins; defines safe signal line bias margin. |
| VBR min/max | 6.4 V / 7.07 V at 10 mA - Confirmed breakdown threshold range; ensures predictable turn-on during overvoltage events. |
| VC @ IPPM | 9.2 V at 54.3 A - Clamped voltage during 500 W surge; determines protected circuit's maximum stress level. |
| PPPM | 500 W (10/1000 µs waveform) - Peak surge energy handling capacity; supports IEC 61000-4-5 Level 4 compliance. |
| TJ max | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |
| MSL Level | Level 1 (J-STD-020) - No floor life limitation; compatible with standard SMT reflow without dry-pack requirements. |
| AEC-Q101 | Qualified - Validated for automotive electronics per stress test requirements including HTGB, HTRB, and TCT. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, bidirectional configuration with no polarity marking. Dimensions: 4.93 mm × 3.99 mm × 2.29 mm (L × W × H); cathode band absent per bidirectional design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode/Cathode (symmetrical) | Transient current path | Both terminals function identically; surge current flows bidirectionally through the same junction structure. |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional clamping | Identical VBR and VC in both directions - eliminates need for orientation-aware placement in AC-coupled or differential lines. |
| Glass passivated junction | Stable, repeatable breakdown with <1 ns response - ensures consistent protection against fast ESD (IEC 61000-4-2) and lightning surges. |
| AEC-Q101 qualification (HE3 suffix) | Validated reliability for automotive ECUs, ADAS sensors, and infotainment systems - includes temperature cycling, humidity testing, and high-temp bias life. |
| Low clamping ratio (VC/VWM) | 1.84 - Minimizes voltage overshoot across protected ICs, enabling compatibility with 5 V logic and USB PHY interfaces. |
| MSL Level 1 rating | No bake requirement prior to reflow - reduces manufacturing complexity and avoids thermal stress on adjacent components. |
Applications
| Automotive Sensor Protection | USB 2.0 Data Line Protection |
|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and radar sensor analog front-ends from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional TVS placed across differential pair or supply rail to clamp transients before reaching sensitive analog inputs. Use Value: Withstands 500 W surges while limiting clamped voltage to 9.2 V - preserves signal integrity and prevents latch-up in 5 V automotive microcontrollers. |

FAQ
What is the polarity configuration of SMA5J5.0CAHE3_A/H?
The SMA5J5.0CAHE3_A/H is a bidirectional TVS diode, meaning it provides symmetrical clamping in both forward and reverse directions. Unlike unidirectional variants, it has no cathode band marking and functions identically regardless of terminal orientation - ideal for AC-coupled or differential signal lines where polarity cannot be guaranteed.
Does SMA5J5.0CAHE3_A/H meet automotive qualification standards?
Yes, SMA5J5.0CAHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3". This qualification covers stress tests including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), temperature cycling (TCT), and unbiased highly accelerated stress testing (UHAST), validating its suitability for under-hood and cabin automotive electronics.
What is the clamping voltage of SMA5J5.0CAHE3_A/H at its rated surge current?
The SMA5J5.0CAHE3_A/H clamps to a maximum of 9.2 V at its peak pulse current (IPPM) of 54.3 A, measured using the standardized 10/1000 µs waveform. This clamping voltage is guaranteed across the full operating temperature range and defines the upper voltage limit imposed on protected circuits during surge events.
Is SMA5J5.0CAHE3_A/H compatible with lead-free reflow processes?
Yes, SMA5J5.0CAHE3_A/H is rated for lead-free reflow with a maximum peak temperature of 260 °C, meeting J-STD-020 MSL Level 1 requirements. Its matte tin-plated leads are solderable per J-STD-002 and JESD 22-B102, and it passes JESD 201 Class 2 whisker testing - ensuring robust interconnect reliability in modern SMT assembly lines.
How does the SMA5J5.0CAHE3_A/H differ from the unidirectional SMA5J5.0AHE3_A/H?
The SMA5J5.0CAHE3_A/H is bidirectional with symmetrical VBR and VC in both directions, while the unidirectional SMA5J5.0AHE3_A/H has a defined cathode band and only clamps in reverse bias. The "CA" suffix explicitly denotes bidirectional functionality, and electrical characteristics such as ID leakage and clamping behavior apply identically across both polarities - critical for protecting AC signals or floating grounds.
