Product details
Overview
SA7.0C-E3/54 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 500 W peak pulse power (10/1000 μs), 7.0 V stand-off voltage (VWM), 7.78–8.60 V breakdown voltage (VBR at 10 mA), 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-E3/54 datasheet, SA7.0C-E3/54 pinout, SA7.0C-E3/54 application, or SA7.0C-E3/54 equivalent, this page delivers verified electrical specs, DO-15 terminal mapping, bi-directional clamping behavior, AEC-Q101 qualification status, and direct alternatives for ESD/lightning transient protection in 12 V and 24 V systems.
Technical Context
The SA7.0C-E3/54 operates as a bi-directional avalanche diode with symmetrical clamping in both polarities, enabling protection of AC-coupled or floating signal paths without polarity concerns. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low leakage (<5 μA at 7.0 V), while meeting JESD22-B106 solderability and JESD201 Class 1A whisker resistance requirements.
It delivers 500 W peak pulse power under standardized 10/1000 μs waveform conditions, with clamping voltage tightly controlled at ≤12.0 V up to 150 A - critical for safeguarding 3.3 V/5 V logic interfaces downstream of level-shifting circuitry. Thermal performance supports continuous operation from −55 °C to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 7.0 V - maximum steady-state reverse voltage before conduction begins; sets operating margin for 12 V nominal bus protection. |
| VBR (min/max) | 7.78 V / 8.60 V at 10 mA - defines precise avalanche onset window; enables predictable clamping threshold selection. |
| VC @ IPPM | ≤12.0 V at 150 A - limits downstream voltage stress during surge events; compatible with 13.2 V absolute max ratings of many automotive MCUs. |
| PPPM | 500 W - peak transient energy handling per 10/1000 μs pulse; sufficient for ISO 7637-2 Pulse 1 & 2a in 12 V systems. |
| IPPM | 150 A - maximum non-repetitive surge current capability; validated per Fig. 3 waveform in Vishay Doc. 88378. |
| TJ range | −55 °C to +175 °C - extended thermal envelope supports under-hood and industrial control cabinet deployment. |
| AEC-Q101 | Qualified - certified for automotive electronic modules per stress test requirements including HTGB, HTRB, and TCT. |

IC Role / Device Role / Timing Role: Fast-response TVS placed across motor terminals or driver output pins to suppress >1 kV spikes generated during commutation. Use Value: Responds in <1 ps to limit voltage rise time, reducing radiated emissions and preventing false triggering of overvoltage protection circuits. |
Use Scenario: Secondary-side transient suppression on 48 V telecom power supply outputs feeding sensitive baseband processors and RF modules. IC Role / Device Role / Timing Role: Bi-directional clamp installed at board edge to absorb coupled lightning surges from backplane interconnects.

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 SMAJ7.0A | Uni-directional; 7.0 V VWM, 7.78–8.6 V VBR, same DO-214AC package but different footprint and polarity marking. | Requires explicit cathode orientation; unsuitable for AC or floating signal lines without series blocking diodes. | Select when polarity is fixed and board space allows SMA package; verify layout compatibility with DO-15 land pattern. |
| ON Semiconductor 1.5KE7.5CA | Higher PPPM (1500 W), same bi-directional function, but larger DO-201AD package and 7.5 V VWM. | Better suited for primary-side 48 V rail protection; over-spec'd for low-voltage signal line use due to higher capacitance (~1000 pF). | Prefer for higher-energy threats where board area permits; avoid in high-speed data lines due to excessive junction capacitance. |
Compared with SMAJ7.0A and 1.5KE7.5CA, SA7.0C-E3/54 offers optimal balance of compact DO-15 form factor, bi-directional symmetry, and precise 7.0 V clamping threshold - making it ideal for space-constrained, polarity-agnostic protection in automotive and industrial control I/O modules.

FAQ
What is the polarity configuration of SA7.0C-E3/54?
The SA7.0C-E3/54 is a bi-directional TVS diode with symmetrical avalanche characteristics in both directions. It has no polarity marking on the DO-15 package, and either lead may be connected to either side of the protected line - eliminating orientation errors during automated assembly and simplifying layout for AC-coupled or floating signals.
Does SA7.0C-E3/54 meet automotive qualification standards?
Yes, SA7.0C-E3/54 is AEC-Q101 qualified per Vishay Document Number 88378. It undergoes stress testing including high-temperature reverse bias (HTRB), high-temperature gate bias (HTGB), and temperature cycling (TCT) to ensure reliability in automotive electronic control units, body modules, and sensor interfaces.
What is the clamping voltage of SA7.0C-E3/54 at its rated peak pulse current?
The SA7.0C-E3/54 clamps to a maximum of 12.0 V at its rated peak pulse current of 150 A under the standard 10/1000 μs waveform. This value is measured per Figure 7 in Vishay's datasheet and reflects worst-case incremental clamping performance at full surge rating.
Can SA7.0C-E3/54 replace SA7.0A in a design?
No - SA7.0C-E3/54 is bi-directional while SA7.0A is uni-directional. Substituting them requires verifying circuit topology: SA7.0C-E3/54 is appropriate for AC, differential, or floating nodes; SA7.0A must be oriented correctly with cathode toward the protected side and cannot protect reverse-polarity transients.
What is the maximum operating temperature for SA7.0C-E3/54?
The SA7.0C-E3/54 has a specified junction temperature range of −55 °C to +175 °C. This allows deployment in under-hood automotive locations, industrial enclosures with ambient temperatures up to +105 °C, and high-power density PCBs where thermal management is constrained.
