Overview
SA7.0C-E3/73 from Vishay General Semiconductor is a bi-directional Transient Voltage Suppressor (TVS) diode in DO-204AC (DO-15) package, designed for clamping voltage transients on signal or power lines. It features 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR) at 10 mA, 500 W peak pulse power (10/1000 μs), and clamps to ≤12.0 V at 150 A peak pulse current - used in automotive sensor interface protection and industrial I/O line surge suppression.
For engineers reviewing the SA7.0C-E3/73 datasheet, SA7.0C-E3/73 pinout, SA7.0C-E3/73 application, or SA7.0C-E3/73 equivalent, this page delivers verified electrical specs, bi-directional TVS behavior, DO-15 mechanical data, AEC-Q101 qualification status, and real-world clamping performance under standardized surge waveforms.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with identical VBR, VC, and IPPM characteristics in forward and reverse directions. Its glass-passivated junction enables fast response (<1 ps) and low incremental surge resistance, critical for protecting sensitive analog inputs and digital communication lines against ESD and inductive switching spikes.
The device complies with AEC-Q101 for automotive use and meets UL 94 V-0 flammability requirements. Its 175 °C maximum junction temperature and 10/1000 μs waveform rating support robust operation in harsh environments without derating below 125 °C ambient.
Key Specifications

|---|---|
| VWM | 7.0 V - Maximum continuous reverse voltage before significant leakage; defines safe operating window for protected circuitry. |
| VBR (min/max) | 7.78 V / 8.60 V at 10 mA - Confirmed breakdown threshold range ensures reliable triggering across process variation and temperature. |
| VC @ IPPM | ≤12.0 V at 150 A - Clamping voltage limits transient energy delivered to downstream ICs during 10/1000 μs surges. |
| PPPM | 500 W - Peak pulse power handling capability per single 10/1000 μs transient event, duty cycle ≤0.01 %. |
| IPPM | 150 A - Maximum non-repetitive peak pulse current supported without degradation; validated per Fig. 3 waveform. |
| TJ max. | 175 °C - Enables operation in under-hood automotive or high-temperature industrial enclosures without thermal shutdown. |
| Leakage ID | 600 μA at VWM - Low standby current minimizes loading on high-impedance sensor bias networks. |

Use Scenario: ESD protection for USB 2.0 D+ and D− lines in portable media players and docking stations. IC Role / Device Role / Timing Role: Localized TVS on each data line, placed immediately adjacent to connector. Use Value: Sub-1 ns response captures HBM ESD events (±15 kV) before damage occurs; low capacitance (<100 pF) avoids signal integrity loss at 480 Mbps. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ7.0A-E3/5A | Uni-directional; 7.0 V VWM, 7.78–8.60 V VBR, same PPPM and VC, but requires correct polarity placement. | Requires polarity-aware layout; unsuitable where AC-coupled or bidirectional signals exist without rectification. | Select SMAJ7.0A-E3/5A only if circuit topology guarantees unidirectional voltage stress and space constraints favor SMC package. |
| 1.5KE7.0CA | Higher PPPM (1500 W), larger DO-201 package (7.1 mm x 5.3 mm), higher VC (12.6 V), same bi-directional function. | Better suited for high-energy surges (e.g., power supply inputs); less ideal for space-constrained signal-line protection. | Choose 1.5KE7.0CA when system-level surge tests exceed 500 W requirements or when board layout allows larger footprint. |
Compared with SA7.0C-E3/73, SMAJ7.0A-E3/5A offers identical clamping performance but demands strict polarity alignment, whereas 1.5KE7.0CA trades compact DO-15 size for higher surge capacity and relaxed thermal design margins - making SA7.0C-E3/73 optimal for cost-sensitive, space-constrained bi-directional signal protection.
