For engineers reviewing the TPSMC13AHE3_A/H datasheet, TPSMC13AHE3_A/H pinout, TPSMC13AHE3_A/H application, or TPSMC13AHE3_A/H equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, SMC package mechanical dimensions, and real-world clamping performance under surge conditions.
Technical Context
This TVS diode uses passivated anisotropic rectifier technology with optimized junction passivation for stable high-temperature operation. Its unidirectional polarity enables forward-biased conduction during overvoltage events while maintaining low leakage (<2.0 μA at VWM) at 25 °C and <10 μA at 150 °C.
The device delivers 1500 W peak pulse power per 10/1000 μs waveform when mounted on 8.0 mm × 8.0 mm copper pads, with clamping voltage tightly controlled at 18.2 V at 82.4 A - enabling robust protection of 12 V automotive systems against ISO 7637-2 and IEC 61000-4-5 surges.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ13A | Lower PPPM (400 W), same VBR range, SMA package (smaller thermal mass) | Limited to low-energy transients; unsuitable for automotive load dump | Select when space-constrained and surge energy ≤400 W; verify thermal dissipation on PCB |
| TPSMC13AHM3_A/H | Identical electrical specs; HM3 suffix denotes halogen-free construction (vs. HE3 RoHS-only) | Required for strict halogen-free BOMs in EU/Asia telecom and industrial markets | Choose HM3 if halogen-free compliance is mandated; otherwise HE3 offers full AEC-Q101 qualification at lower cost |

FAQ
What is the clamping voltage of TPSMC13AHE3_A/H at its rated peak pulse current?
The TPSMC13AHE3_A/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated peak pulse current (IPPM) of 82.4 A under a 10/1000 μs waveform. This value is measured per Figure 1 in the official Vishay datasheet (Document Number: 88407) and defines the upper voltage limit imposed on protected circuits during worst-case surge events. The TPSMC13AHE3_A/H maintains this clamping performance across its full operating temperature range.
Is TPSMC13AHE3_A/H qualified for automotive applications?
Yes, TPSMC13AHE3_A/H is AEC-Q101 qualified, as confirmed by Vishay's ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified variants. The device undergoes rigorous stress testing including high-temperature reverse bias, temperature cycling, and humidity testing per AEC-Q101 Rev D. This qualification makes TPSMC13AHE3_A/H suitable for use in engine control units, body electronics, and ADAS modules where automotive-grade reliability is mandatory.
What is the standoff voltage (VWM) of TPSMC13AHE3_A/H, and why does it matter?
The standoff voltage (VWM) of TPSMC13AHE3_A/H is 11.1 V - the maximum continuous reverse voltage the device can block without significant leakage. This parameter ensures compatibility with nominal 12 V automotive systems, allowing the TPSMC13AHE3_A/H to remain non-conductive during normal operation while still triggering reliably during overvoltage events. At 25 °C, reverse leakage is ≤2.0 μA, rising to ≤10 μA at 150 °C, preserving system efficiency and signal integrity.
Does TPSMC13AHE3_A/H have a unidirectional or bidirectional configuration?
TPSMC13AHE3_A/H is unidirectional only, as explicitly stated in the Vishay datasheet under FEATURES. Its polarity is marked by a cathode band, and it conducts surge current only when the cathode is at higher potential than the anode - making it appropriate for DC power line protection where polarity is fixed. Bidirectional variants (e.g., TPSMC13CA) are separate part numbers and not interchangeable with TPSMC13AHE3_A/H.
What package type does TPSMC13AHE3_A/H use, and what are its key mechanical attributes?
TPSMC13AHE3_A/H uses the SMC (DO-214AB) surface-mount package, measuring 7.11 mm × 6.22 mm × 2.62 mm (length × width × height). It features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102, meets UL 94 V-0 flammability rating, and is rated MSL Level 1 for reflow compatibility up to 260 °C peak. The cathode band provides clear polarity identification, and the package supports thermal dissipation via 8.0 mm × 8.0 mm copper pads per terminal as specified in the datasheet.
