Overview
SMA5J6.0CHE3/5A from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for clamping voltage transients on power and signal lines. It features a 6.0 V stand-off voltage (VWM), 6.67–7.37 V breakdown voltage (VBR at 10 mA), 500 W peak pulse power (10/1000 µs), 48.5 A peak pulse current (IPPM), and clamps to ≤10.3 V at rated surge. It is AEC-Q101 qualified and used in automotive sensor line protection.
For engineers reviewing the SMA5J6.0CHE3/5A datasheet, SMA5J6.0CHE3/5A pinout, SMA5J6.0CHE3/5A application, or SMA5J6.0CHE3/5A equivalent, key selection criteria include bi-directional clamping capability, 500 W surge rating with low clamping voltage, AEC-Q101 qualification for automotive use, RoHS compliance with HE3 whisker-tested leads, and DO-214AC thermal performance under repetitive surge conditions.
Technical Context
This bi-directional TVS diode operates symmetrically in both polarities, with identical electrical characteristics forward and reverse. Its glass-passivated junction ensures stable breakdown behavior and fast response (<1 ns), while low incremental surge resistance enables effective energy diversion during ESD or load-switching transients.
The device is rated for 150 °C maximum junction temperature and exhibits 80 °C/W typical junction-to-ambient thermal resistance when mounted on 5.0 mm × 5.0 mm copper pads. It meets MSL Level 1 per J-STD-020 and supports lead-free reflow up to 260 °C peak.

|---|---|
Use Scenario: Protecting LIN bus or analog sensor outputs (e.g., pressure, temperature) from load-dump and inductive switching transients in vehicle chassis modules. IC Role / Device Role / Timing Role: Bi-directional voltage clamp placed directly at connector entry point to shunt surge energy before reaching ASIC or MCU input pins. Use Value: Maintains signal integrity under ISO 16750-2 Pulse 5a (75 V/300 ms) by clamping to ≤10.3 V, preventing latch-up or gate oxide damage in 5 V tolerant receivers. |
Use Scenario: Safeguarding 24 V DC digital input channels on programmable logic controllers exposed to relay coil flyback and field wiring surges. IC Role / Device Role / Timing Role: Primary transient suppression element across input terminals, working in concert with series current-limiting resistor and optocoupler isolation. Use Value: Withstands repeated 500 W surges per IEC 61000-4-5 Combination Wave (1.2/50 µs + 8/20 µs), extending mean time between failures in factory automation environments. |
| Telecom Power Rail Protection | Consumer USB Port ESD Suppression |
Use Scenario: Secondary protection on -48 V telecom power distribution boards subject to lightning-induced surges entering via long cable runs. IC Role / Device Role / Timing Role: Coordinated clamping device downstream of gas discharge tube (GDT) primary protector, providing fast-response secondary clamping. Use Value: Fast <1 ns response complements slower GDTs; 500 W rating handles residual energy after GDT crowbarring, limiting let-through voltage to safe levels for DC-DC converters. |
Use Scenario: ESD protection on USB 2.0 VBUS and D+/D− lines in portable media players where space constraints favor single-device bi-directional coverage. IC Role / Device Role / Timing Role: Standalone bi-directional TVS replacing dual-unidirectional arrays, reducing component count and board area on compact PCBs. Use Value: Single DO-214AC footprint protects both power and data lines simultaneously against ±15 kV contact discharge (IEC 61000-4-2), eliminating need for separate VBUS and signal-line suppressors. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ6.0A | Uni-directional; 6.67–7.37 V VBR, same VC (10.3 V), but requires correct polarity orientation and lacks AEC-Q101 certification. | Suitable only where polarity is fixed and automotive qualification is not required; cannot replace SMA5J6.0CHE3/5A in bi-directional or automotive contexts. | Select only for cost-sensitive industrial applications with known unidirectional bias and no automotive compliance mandate. |
| ON Semiconductor 1.5SMC6.0A | Same bi-directional function and VWM/VBR specs, but in larger DO-214AB (SMB) package; higher RθJA (60 °C/W vs. 80 °C/W) and lower surge rating (1500 W vs. 500 W). | Offers higher peak power but occupies more board area; thermal performance less optimized for dense layouts. | Prefer when system-level surge requirements exceed 500 W and PCB real estate allows SMB footprint; avoid if AEC-Q101 or space-constrained design is critical. |
Compared with SMAJ6.0A and 1.5SMC6.0A, the SMA5J6.0CHE3/5A uniquely combines bi-directional operation, AEC-Q101 qualification, DO-214AC compactness, and verified 500 W surge capability - making it the only choice for space-limited automotive sensor nodes requiring zero-polarity-installation and full automotive reliability validation.

FAQ
What is the polarity configuration of SMA5J6.0CHE3/5A?
The SMA5J6.0CHE3/5A is a bi-directional TVS diode with symmetrical terminal behavior - neither end is marked as anode or cathode, and it provides identical clamping performance in both directions. This eliminates polarity-checking during placement and simplifies layout for AC-coupled or floating signal lines. The device's CA suffix explicitly denotes bi-directionality, and its datasheet confirms equal VBR, VC, and IPPM ratings for positive and negative surges. SMA5J6.0CHE3/5A is therefore ideal for protecting differential buses or ungrounded power rails where voltage reversal may occur.
Is SMA5J6.0CHE3/5A qualified for automotive applications?
Yes, SMA5J6.0CHE3/5A carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per ANSI/ESDA/JEDEC JS-001. The device is rated for operation from −55 °C to +150 °C junction temperature and is approved for use in engine control units, body electronics, and ADAS sensor interfaces. SMA5J6.0CHE3/5A meets automotive surge immunity standards including ISO 7637-2 and ISO 16750-2 when applied per recommended layout guidelines.
What is the maximum clamping voltage of SMA5J6.0CHE3/5A under surge conditions?
The maximum clamping voltage (VC) of SMA5J6.0CHE3/5A is 10.3 V, measured at its rated peak pulse current (IPPM) of 48.5 A under a 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage imposed on the protected circuit during worst-case transient events. SMA5J6.0CHE3/5A maintains this clamping performance consistently due to its low incremental surge resistance and glass-passivated junction, making it suitable for safeguarding 5 V logic interfaces and analog sensors without risk of overvoltage damage.
Does SMA5J6.0CHE3/5A require special PCB layout considerations?
Yes - optimal performance of SMA5J6.0CHE3/5A requires mounting on minimum 5.0 mm × 5.0 mm copper pads per terminal to achieve specified thermal resistance (RθJA = 80 °C/W) and surge current handling. Short, wide traces must connect the device directly across the protected line and ground, avoiding vias or narrow necks that increase inductance and degrade clamping speed. SMA5J6.0CHE3/5A should be placed as close as possible to the connector or IC pin being protected, with ground return path minimized to reduce loop inductance. These practices ensure sub-1 ns response and full 500 W surge capability.
How does the HE3 suffix differ from E3 in SMA5J6.0CHE3/5A?
The HE3 suffix in SMA5J6.0CHE3/5A indicates RoHS-compliant construction with AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 denotes RoHS compliance only (commercial grade, no automotive qualification). HE3 devices undergo extended reliability testing including 1000-hour HTRB and temperature cycling, and feature enhanced lead finish durability for high-reliability solder joints. SMA5J6.0CHE3/5A is therefore certified for mission-critical automotive use, while SMA5J6.0AE3/5A is restricted to non-automotive applications. Both share identical electrical specs and DO-214AC packaging.
