Product details
Overview
SMAJ5.0C-E3/61 from Vishay General Semiconductor is a bi-directional surface-mount Transient Voltage Suppressor (TVS) diode in DO-214AC (SMA) package, rated for 5.0 V stand-off voltage, 41.7 V clamping voltage at 9.6 A peak pulse current, and 400 W peak pulse power with 10/1000 µs waveform - deployed to protect ICs and MOSFETs against ESD and lightning-induced transients in automotive sensor signal lines.
For engineers reviewing the SMAJ5.0C-E3/61 datasheet, SMAJ5.0C-E3/61 pinout, SMAJ5.0C-E3/61 application, or SMAJ5.0C-E3/61 equivalent, this page delivers verified electrical parameters, JEDEC-compliant thermal resistance data, RoHS-compliant packaging details, and real-world protection use cases for industrial and automotive electronics design.
Technical Context
This bi-directional TVS operates symmetrically in both polarities, with breakdown voltage range of 6.40–7.82 V at 10 mA test current and maximum reverse leakage of 800 µA at 5.0 V stand-off. Its low clamping ratio (VC/VWM = 8.34) ensures minimal overvoltage stress during surge events.
Designed for high-reliability mounting on 0.2 × 0.2 inch copper pads, it achieves 120 °C/W junction-to-ambient thermal resistance and supports repetitive 0.01 % duty cycle surges. It meets MSL Level 1 per J-STD-020 and passes JESD201 Class 1A whisker testing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Stand-off Voltage (VWM) | 5.0 V - Maximum continuous reverse operating voltage before conduction begins |
| Clamping Voltage (VC) | 41.7 V at 9.6 A - Peak voltage seen by protected circuit during 10/1000 µs transient |
| Peak Pulse Power (PPPM) | 400 W - Surge energy handling capability under standard 10/1000 µs waveform |
| Breakdown Voltage (VBR) | 6.40–7.82 V at 10 mA - Confirmed avalanche onset range ensuring predictable turn-on |
| Reverse Leakage (ID) | 800 µA max at VWM - Low quiescent current avoids loading sensitive signal paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ5.0CA-E3/61 | Same VWM (5.0 V), identical DO-214AC package, but marked CA suffix confirms bi-directional qualification per datasheet Table 1 | No functional difference - CA and C suffixes both denote bi-directional variants in this family | Select SMAJ5.0CA-E3/61 when explicit CA marking is required for traceability or internal BOM policy |
| P6SMB5.0C-E3/52 | Same 5.0 V VWM and bi-directional function, but in larger DO-214AA (SMB) package with 600 W PPPM rating | Higher power handling suits higher-energy surge environments; requires larger PCB footprint | Choose P6SMB5.0C-E3/52 only if system-level testing demands >400 W surge margin or legacy SMB layout reuse |
Compared with SMAJ5.0C-E3/61, SMAJ5.0CA-E3/61 offers identical electrical and mechanical performance with alternate marking, while P6SMB5.0C-E3/52 trades compact size for higher surge capacity - making SMAJ5.0C-E3/61 optimal for space-constrained automotive and consumer designs requiring certified 400 W protection.

FAQ
What is the clamping voltage of SMAJ5.0C-E3/61 at its rated peak pulse current?
The SMAJ5.0C-E3/61 has a maximum clamping voltage (VC) of 41.7 V at 9.6 A peak pulse current under the standard 10/1000 µs waveform. This value is measured per Figure 1 and Table 1 of Vishay document 88390 and defines the upper voltage limit imposed on protected circuits during surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is SMAJ5.0C-E3/61 unidirectional or bidirectional, and how is polarity identified?
SMAJ5.0C-E3/61 is a bi-directional TVS diode, meaning it provides symmetrical clamping for positive and negative transients. Per Vishay documentation, bi-directional types like SMAJ5.0C-E3/61 have no polarity marking - both terminals are functionally identical, and the device conducts identically in either direction above its breakdown threshold.
Does SMAJ5.0C-E3/61 meet automotive reliability standards?
SMAJ5.0C-E3/61 is RoHS-compliant and qualified to MSL Level 1 per J-STD-020, but the base E3 suffix denotes commercial grade. For automotive applications, Vishay specifies the HE3 suffix (e.g., SMAJ5.0CHE3/61) for AEC-Q101 qualification - SMAJ5.0C-E3/61 itself is not AEC-Q101 certified and should be validated per end-equipment requirements.
What is the maximum reverse leakage current for SMAJ5.0C-E3/61 at its stand-off voltage?
The SMAJ5.0C-E3/61 exhibits a maximum reverse leakage current (ID) of 800 µA at its 5.0 V stand-off voltage (VWM), tested at TA = 25 °C. This low leakage ensures minimal impact on high-impedance sensor bias networks and preserves battery life in always-on automotive modules where SMAJ5.0C-E3/61 is commonly deployed.
Can SMAJ5.0C-E3/61 be used in place of SMAJ5.0A-E3/61?
No - SMAJ5.0C-E3/61 is bi-directional, while SMAJ5.0A-E3/61 is uni-directional with cathode band marking. Substituting them risks failure: SMAJ5.0A-E3/61 would short-circuit on negative transients in bi-directional applications. The "C" and "A" suffixes denote fundamental functional differences confirmed in Table 1 of Vishay document 88390 - SMAJ5.0C-E3/61 must only replace other C- or CA-suffix parts.
