Product details
Overview
TPSMC13HE3_A/H from Vishay General Semiconductor is a unidirectional surface-mount transient voltage suppressor (TVS) diode in DO-214AB (SMC) package, designed for high-reliability overvoltage protection of sensitive electronics. It features 13 V breakdown voltage (VBR min/max: 11.7 V / 14.3 V), 10.5 V stand-off voltage (VWM), 1500 W peak pulse power (10/1000 μs), and 185 °C maximum junction temperature - enabling robust protection in automotive and industrial power rails.
For engineers reviewing the TPSMC13HE3_A/H datasheet, TPSMC13HE3_A/H pinout, TPSMC13HE3_A/H application, or TPSMC13HE3_A/H equivalent, key selection criteria include clamping voltage (19 V at 78.9 A), unidirectional polarity, AEC-Q101 qualification, and MSL Level 1 reflow compatibility - all critical for automotive-grade ESD/surge protection design validation.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology to deliver fast response time (<1 ns), low incremental surge resistance, and stable clamping under repetitive transients. Its 185 °C junction rating supports operation in under-hood automotive environments and high-temperature industrial control systems without derating penalties up to 150 °C ambient.
The device is optimized for single-pulse 10/1000 μs waveform suppression with 78.9 A peak surge current (IPPM) and 19 V maximum clamping voltage (VC). Its unidirectional configuration provides forward conduction path during positive transients while blocking reverse leakage (≤2 μA at 10.5 V, ≤10 μA at 150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 11.7 V / 14.3 V - defines reliable avalanche initiation range at 1 mA test current; ensures consistent turn-on across temperature and lot variation |
| VWM | 10.5 V - maximum continuous reverse operating voltage; sets safe margin below breakdown for stable DC bias operation |
| VC @ IPPM | 19 V at 78.9 A - clamping voltage during 10/1000 μs surge; determines protected IC's maximum stress level |
| PPPM | 1500 W - peak pulse power handling capability; enables protection against ISO 7637-2 Pulse 1/2a/5a and IEC 61000-4-5 surges |

Equivalent & Alternatives
The following parts are listed as comparable options for similar unidirectional TVS diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | DO-214AC (SMA) package; lower PPPM (400 W); VC = 21.5 V at 19.3 A | Not AEC-Q101 qualified; limited to consumer/industrial use; insufficient for automotive load dump | Select only for cost-sensitive, non-automotive designs with lower surge exposure |
| 1.5SMC13A | Same DO-214AB package; identical VBR/VWM; but rated for 1500 W with 1.5 kW marking - no AEC-Q101 or HE3 suffix | Lacks automotive qualification and whisker-tested terminations; not approved for safety-critical vehicle systems | Acceptable for industrial controls where AEC-Q101 is not mandated, but requires requalification for automotive reuse |
Compared with SMAJ13A and 1.5SMC13A, the TPSMC13HE3_A/H delivers verified AEC-Q101 compliance, 185 °C operation, and JESD201 Class 2 whisker resistance - making it the only option qualified for production automotive ECUs without additional qualification effort.

FAQ
What is the clamping voltage of the TPSMC13HE3_A/H and how is it measured?
The TPSMC13HE3_A/H has a maximum clamping voltage (VC) of 19 V, measured at its peak pulse current (IPPM) of 78.9 A using a standardized 10/1000 μs double-exponential surge waveform. This value is guaranteed per Vishay's datasheet (Document Number: 88407, Rev. 22-Jul-16) and reflects worst-case voltage seen by downstream circuitry during surge events - critical for validating protection margins in 12 V systems.
Is the TPSMC13HE3_A/H AEC-Q101 qualified and what does that cover?
Yes, the TPSMC13HE3_A/H is explicitly AEC-Q101 qualified, as confirmed in the Vishay datasheet footnote on page 3. This qualification covers stress testing for temperature cycling, humidity bias, mechanical shock, vibration, and high-temperature operating life - validating suitability for automotive electronic control units, body modules, and ADAS subsystems where reliability is mission-critical.
What is the meaning of the 'HE3_A/H' suffix in TPSMC13HE3_A/H?
The 'HE3' suffix indicates RoHS-compliance and AEC-Q101 qualification with JESD201 Class 2 whisker resistance; 'A' denotes ±5 % tolerance on VBR; and '/H' specifies packaging in 7-inch plastic tape and reel (850 units per reel). This full suffix confirms the part meets automotive-grade material, process, and packaging requirements - distinct from non-HE3 variants.
Can the TPSMC13HE3_A/H be used in bidirectional protection configurations?
No, the TPSMC13HE3_A/H is unidirectional only, as stated in the Vishay datasheet Features section. It conducts only during positive transients (cathode-to-anode) and blocks reverse current. For bidirectional protection, a separate device such as the TPSMC13CA (center-tapped, bidirectional variant) must be selected - the TPSMC13HE3_A/H cannot substitute without circuit redesign.
What is the maximum operating temperature and thermal derating behavior of the TPSMC13HE3_A/H?
The TPSMC13HE3_A/H supports a maximum junction temperature (TJ) of +185 °C and operates continuously from –65 °C to +185 °C. Its peak pulse power is derated linearly above 25 °C ambient, per Figure 2 in the datasheet: at 125 °C ambient, PPPM drops to ~70 % of 1500 W. This enables use in high-temperature locations like engine compartments without external heatsinking.
