Product details
Overview
SMA5J30CHE3/61 from Vishay General Semiconductor is a bi-directional transient voltage suppressor (TVS) diode in DO-214AC (SMA) package, designed for high-energy surge protection on signal and power lines. It features a 30 V stand-off voltage (VWM), 33.3–36.8 V breakdown voltage (VBR) at 1 mA, 500 W peak pulse power (10/1000 µs), clamping voltage of 48.4 V at 10.3 A IPPM, and AEC-Q101 qualification for automotive use.
For engineers reviewing the SMA5J30CHE3/61 datasheet, SMA5J30CHE3/61 pinout, SMA5J30CHE3/61 application, or SMA5J30CHE3/61 equivalent, key selection criteria include bi-directional clamping capability, low incremental surge resistance, MSL level 1 moisture sensitivity, and compatibility with automated SMT placement on PCBs requiring robust ESD and lightning surge immunity.
Technical Context
This TVS diode operates symmetrically in both directions, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ps), while the DO-214AC package provides thermal resistance of 80 °C/W (junction-to-ambient) and supports 150 °C maximum junction temperature.
The device meets AEC-Q101 stress test requirements for automotive applications and is rated for non-repetitive 10/1000 µs surge pulses up to 500 W. Its clamping performance-VC = 48.4 V at IPPM = 10.3 A-ensures reliable overvoltage limiting for sensitive downstream ICs such as CAN transceivers, sensor interfaces, and microcontroller I/O pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 30 V - Maximum continuous reverse operating voltage before clamping begins; defines safe working range for protected circuit. |
| VBR (min/max) | 33.3 V / 36.8 V - Breakdown occurs within this band at 1 mA test current; ensures predictable turn-on threshold. |
| VC @ IPPM | 48.4 V at 10.3 A - Clamped voltage during 10/1000 µs surge; limits stress on downstream components. |
| PPPM | 500 W - Peak pulse power handling capacity; determines survivability against lightning or inductive switch transients. |
| TJ max. | +150 °C - Maximum junction temperature; enables operation in under-hood automotive environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J30CA-E3/61 | Same electrical specs and DO-214AC package; differs only in RoHS compliance labeling (E3 vs HE3) and qualification scope-E3 is commercial grade, HE3 is AEC-Q101 qualified. | Not suitable for automotive applications requiring AEC-Q101 validation; acceptable for industrial/commercial designs with lower reliability requirements. | Select SMA5J30CHE3/61 when AEC-Q101 compliance is mandatory; choose SMA5J30CA-E3/61 for cost-sensitive non-automotive use. |
| SMCJ33CAHE3/A | Higher PPPM (1500 W), larger DO-214AB (SMC) package, VWM = 33 V, VC = 53.3 V at 28.3 A; not pin-compatible due to different footprint and thermal mass. | Better suited for higher-energy threats (e.g., 4 kV IEC 61000-4-5), but requires PCB redesign and increased board area. | Choose SMCJ33CAHE3/A only when surge energy exceeds 500 W rating and layout allows SMC footprint; SMA5J30CHE3/61 remains optimal for space-constrained 500 W protection. |
Compared with SMA5J30CA-E3/61, SMA5J30CHE3/61 adds AEC-Q101 qualification without electrical trade-offs; versus SMCJ33CAHE3/A, it offers identical bi-directional function in a smaller SMA package at lower surge capacity-making it ideal for compact automotive and industrial modules where 500 W suffices.

FAQ
What is the polarity configuration of SMA5J30CHE3/61?
SMA5J30CHE3/61 is a bi-directional TVS diode with symmetrical terminal behavior-neither end is marked as anode or cathode. This allows flexible placement across AC-coupled or floating signal paths without orientation constraints, unlike uni-directional variants that require correct polarity alignment relative to ground.
Does SMA5J30CHE3/61 meet automotive qualification standards?
Yes, SMA5J30CHE3/61 is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), unbiased highly accelerated stress test (UHAST), and mechanical shock. The "HE3" suffix explicitly denotes AEC-Q101 qualification and RoHS compliance per JEDEC JS709A halogen-free standards.
What is the clamping voltage of SMA5J30CHE3/61 under surge conditions?
The clamping voltage of SMA5J30CHE3/61 is 48.4 V measured at 10.3 A peak pulse current (IPPM) using the standardized 10/1000 µs waveform. This value represents the maximum voltage imposed on the protected circuit during a defined transient event, ensuring downstream ICs remain within safe operating limits.
Is SMA5J30CHE3/61 compatible with lead-free reflow processes?
Yes, SMA5J30CHE3/61 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 comply with J-STD-002 for solderability, and the DO-214AC package withstands standard IPC/JEDEC G-104 thermal profiles without delamination or parametric shift.
How does SMA5J30CHE3/61 differ from SMA5J30A variants?
SMA5J30CHE3/61 is bi-directional (CA suffix), whereas SMA5J30A is uni-directional (A suffix). The bi-directional version has no polarity marking and clamps equally in both directions, making it suitable for AC signals and differential buses; the uni-directional variant requires correct cathode orientation and conducts forward current during overvoltage events.
