Product details
Overview
TPSMA13AHE3_B/H from Vishay General Semiconductor is a unidirectional surface-mount PAR® transient voltage suppressor (TVS) designed for clamping inductive switching surges and lightning-induced transients on power and signal lines. It features a 13.0 V nominal breakdown voltage (VBR), 22.0 A peak pulse current (IPPM) at 10/1000 µs, 400 W peak pulse power (PPPM), 185 °C maximum junction temperature, and SMA (DO-214AC) package - used in automotive sensor protection and industrial I/O interface circuits.
For engineers reviewing the TPSMA13AHE3_B/H datasheet, TPSMA13AHE3_B/H pinout, TPSMA13AHE3_B/H application, or TPSMA13AHE3_B/H equivalent, key selection criteria include clamping voltage (18.2 V at IPPM), unidirectional polarity, AEC-Q101 qualification status, thermal derating above 25 °C, and compatibility with J-STD-020 MSL level 1 reflow profiles.
Technical Context
This TVS diode employs passivated anisotropic rectifier technology to achieve low incremental surge resistance and excellent clamping capability under repetitive 10/1000 µs transients. Its 185 °C junction rating enables operation in high-temperature automotive engine compartments and industrial motor control environments.
The device delivers 18.2 V clamping voltage at 22.0 A peak pulse current, with 0.072 %/°C temperature coefficient of VBR, ensuring predictable voltage threshold shift across operating temperature. It meets JESD201 Class 2 whisker resistance and UL 94 V-0 flammability requirements for PCB-mounted reliability.

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) from load dump and ESD in vehicle ECUs. IC Role / Device Role / Timing Role: Unidirectional TVS placed between signal line and chassis ground to clamp transients before reaching sensitive analog front-end or transceiver ICs. Use Value: 18.2 V clamping voltage ensures signal integrity remains within ±10% of 12 V supply rails during 400 W surges, preserving ADC accuracy and communication timing margins. |
Use Scenario: Safeguarding digital input modules in programmable logic controllers exposed to inductive switching noise from solenoids and contactors. IC Role / Device Role / Timing Role: Standoff protection element on 24 V DC input channels, absorbing repetitive 10/1000 µs transients induced by relay bounce or motor startup. Use Value: 185 °C junction rating allows uninterrupted operation in sealed control cabinets with ambient temperatures up to 105 °C, eliminating thermal derating penalties. |
| Consumer Power Adapter Surge Suppression | Telecom Line Interface Protection |
Use Scenario: Secondary-side overvoltage suppression in AC/DC adapters for smart home devices subjected to lightning-induced surges on low-voltage DC outputs. IC Role / Device Role / Timing Role: Final-stage clamping device on regulated 5 V/12 V output rails, shunting energy away from USB-PD controllers and PMICs. Use Value: 22.0 A IPPM capacity handles multiple 10/1000 µs pulses without degradation, supporting UL 62368-1 surge immunity compliance. |
Use Scenario: Protection of Ethernet PHY interfaces and PoE injectors against fast-rising transients coupled onto twisted-pair cabling in building infrastructure. IC Role / Device Role / Timing Role: Bidirectional-capable layout not applicable; this unidirectional device used on DC bias lines (e.g., PoE power feed) where polarity is fixed. Use Value: 0.072 %/°C VBR tempco ensures stable clamping threshold across -40 °C to +85 °C telecom operating range, preventing false triggering. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13A | Same VBR (13.0 V) and PPPM (600 W), but larger SMB (DO-214AA) package; 30.0 V VC vs. 18.2 V | Higher clamping voltage increases stress on protected ICs; requires larger PCB area | Select when higher peak power margin is needed and board space permits larger footprint |
| TPSMA13AHM3_B/H | Identical electrical specs; halogen-free molding compound and JESD201 Class 2 whisker resistance - same SMA package | No functional difference; required for RoHS+halogen-free compliance programs | Choose for green manufacturing initiatives without altering circuit design or layout |
Compared with TPSMA13AHE3_B/H, SMBJ13A offers greater surge margin but compromises clamping performance and board density, while TPSMA13AHM3_B/H provides identical protection with enhanced environmental compliance - making the HE3 variant optimal for cost-sensitive AEC-Q101 automotive designs where halogen content is unrestricted.

FAQ
What is the clamping voltage of the TPSMA13AHE3_B/H at its rated peak pulse current?
The TPSMA13AHE3_B/H has a maximum clamping voltage (VC) of 18.2 V when subjected to its rated 22.0 A peak pulse current (IPPM) under the standard 10/1000 µs waveform. This value is measured at TA = 25 °C with specified PCB pad layout and represents the upper limit of voltage seen by downstream components during surge events. The TPSMA13AHE3_B/H maintains this clamping performance across its full operating temperature range due to its low 0.072 %/°C VBR temperature coefficient.
Is the TPSMA13AHE3_B/H qualified for automotive applications?
Yes, the TPSMA13AHE3_B/H is AEC-Q101 qualified, as confirmed by Vishay's documentation and ordering code suffix "HE3", which denotes RoHS-compliant and AEC-Q101 qualified construction. It undergoes rigorous testing including temperature cycling, highly accelerated stress testing (HAST), and mechanical shock per AEC-Q101 requirements. The TPSMA13AHE3_B/H supports automotive use cases such as engine control unit sensor protection and body electronics I/O conditioning.
What does the "HE3" suffix indicate in TPSMA13AHE3_B/H?
The "HE3" suffix in TPSMA13AHE3_B/H identifies the part as RoHS-compliant and AEC-Q101 qualified, with matte tin-plated leads meeting J-STD-002 solderability and JESD22-B102 mechanical endurance standards. The "B/H" denotes packaging: 7-inch diameter plastic tape and reel, 1800 units per reel. The TPSMA13AHE3_B/H uses passivated anisotropic rectifier technology and is rated for 185 °C maximum junction temperature - all attributes defined under the HE3 qualification umbrella.
How does the TPSMA13AHE3_B/H compare to bidirectional TVS diodes?
The TPSMA13AHE3_B/H is unidirectional and protects only against positive-going transients relative to ground, unlike bidirectional TVS diodes that suppress both polarities. Its 11.1 V stand-off voltage (VWM) and 13.0 V breakdown make it suitable for DC-biased lines such as automotive 12 V supplies or industrial 24 V inputs. For AC or floating signal lines, a bidirectional device would be required - the TPSMA13AHE3_B/H is not interchangeable in those roles without circuit redesign.
What is the thermal derating behavior of the TPSMA13AHE3_B/H above 25 °C ambient?
The TPSMA13AHE3_B/H follows Vishay's standard derating curve (Fig. 2 in document 88405): peak pulse power decreases linearly from 400 W at 25 °C to zero at 185 °C junction temperature. At 100 °C ambient with typical PCB copper pad layout, the device retains approximately 65% of its rated PPPM. Derating is calculated using junction-to-ambient thermal resistance and actual power dissipation - the TPSMA13AHE3_B/H's 185 °C TJ max. enables operation in high-ambient environments where lower-rated TVS diodes would fail.
