Product details
Overview
1.5SMC13CAHE3/57T from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in the SMC (DO-214AB) package, rated for 1500 W peak pulse power (10/1000 μs), with a standoff voltage of 11.1 V, clamping voltage of 18.2 V at 82.4 A, and AEC-Q101 qualification for automotive applications. It protects signal lines and power rails in sensor interfaces and ECU inputs against lightning-induced surges and inductive switching transients.
For engineers reviewing the 1.5SMC13CAHE3/57T datasheet, 1.5SMC13CAHE3/57T pinout, 1.5SMC13CAHE3/57T application, or 1.5SMC13CAHE3/57T equivalent, this page delivers verified electrical parameters, thermal derating behavior, bidirectional clamping performance, RoHS-compliant and automotive-grade construction details, and real-world protection use cases aligned with IEC 61000-4-5 surge immunity requirements.
Technical Context
The 1.5SMC13CAHE3/57T operates as a bidirectional avalanche-clamped TVS diode, exhibiting symmetrical breakdown in both polarities with VBR = 12.4–13.7 V at 1.0 mA test current and clamping voltage VC = 18.2 V at IPPM = 82.4 A under 10/1000 μs waveform. Its low incremental surge resistance ensures minimal voltage overshoot during fast transients.
Designed for surface-mount assembly on 8.0 mm × 8.0 mm copper pads, it achieves RθJA = 75 °C/W and RθJL = 15 °C/W, supports operating junction temperatures from –65 °C to +150 °C, and meets J-STD-020 MSL Level 1 with peak reflow at 260 °C - enabling robust automated production in automotive and industrial environments.

|---|---|
Use Scenario: Protecting CAN/LIN bus transceivers and analog sensor inputs (e.g., pressure, temperature) in engine control units against load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping element placed directly at connector entry point to shunt surge energy before reaching signal conditioning circuitry. Use Value: Limits transient voltage to ≤18.2 V during 82.4 A surges, preserving integrity of 12 V rail-connected microcontrollers and ADC front-ends. |
Use Scenario: Safeguarding 4–20 mA current loop inputs and ±10 V analog inputs in programmable logic controllers exposed to motor drive noise and relay switching transients. IC Role / Device Role / Timing Role: Fast-response TVS placed across input terminals to clamp sub-100 ns spikes induced by nearby inductive loads. Use Value: Maintains signal fidelity by clamping within 1 ns while sustaining 1500 W peak power - preventing latch-up or damage to precision op-amps and isolators. |
| Telecom Power Rail Protection | Consumer Appliance Motor Drive Protection |
Use Scenario: Shielding DC power inputs (e.g., 12 V/24 V PoE-derived rails) in base station radios and fiber access nodes from lightning-induced surges on outdoor cabling. IC Role / Device Role / Timing Role: Primary overvoltage suppression stage upstream of DC-DC converters and LDO regulators. Use Value: Withstands repetitive 10/1000 μs surges at 0.01% duty cycle, ensuring uninterrupted operation during multi-event storm conditions. |
Use Scenario: Guarding microcontroller GPIOs and gate drivers in washing machine, HVAC, and power tool inverters against back-EMF from brushed/BLDC motors. IC Role / Device Role / Timing Role: Low-capacitance (typ. <100 pF) bidirectional suppressor placed at motor driver IC supply pins and feedback node connections. Use Value: Prevents false triggering and latch-up in 3.3 V/5 V logic circuits by limiting clamped voltage to 18.2 V while adding negligible signal distortion. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA | Lower peak power rating (600 W), same VWM/VC but higher clamping ratio; SMB package (smaller footprint, higher RθJA) | Suitable for space-constrained consumer electronics where surge severity is lower (IEC 61000-4-5 Level 2) | Select when board area is critical and surge threat level does not exceed 2 kV; verify thermal margin with RθJA = 110 °C/W |
| 1.5KE13CA | Through-hole TO-204AA (DO-41) package; identical electrical specs but slower response due to higher parasitic inductance | Fits legacy designs with through-hole assembly or where manual repairability is prioritized over automated SMT yield | Choose only if existing PCB layout prohibits SMT components; avoid in high-frequency or compact automotive modules |
Compared with SMBJ13CA and 1.5KE13CA, the 1.5SMC13CAHE3/57T delivers superior surge handling (1500 W vs. 600 W or 1500 W with inferior thermal performance), AEC-Q101 validation for automotive use, and optimized SMT manufacturability - making it the preferred choice for new automotive, industrial, and telecom designs requiring high-reliability transient suppression.

FAQ
What is the clamping voltage of the 1.5SMC13CAHE3/57T at its rated peak pulse current?
The 1.5SMC13CAHE3/57T has a maximum clamping voltage (VC) of 18.2 V at its rated peak pulse current (IPPM) of 82.4 A under the standardized 10/1000 μs double-exponential waveform. This value is measured per Figure 1 in Vishay document 88303 and reflects the actual voltage imposed on protected circuitry during worst-case surge events - critical for ensuring downstream ICs remain within absolute maximum ratings.
Is the 1.5SMC13CAHE3/57T suitable for automotive applications?
Yes, the 1.5SMC13CAHE3/57T is explicitly AEC-Q101 qualified (as indicated by the "HE3" suffix), meaning it has passed rigorous stress tests including temperature cycling, high-temperature reverse bias, and ESD per JESD22 standards. Its construction, thermal performance, and guaranteed parametric stability across –65 °C to +150 °C make it approved for use in engine control units, ADAS camera modules, and body electronics where automotive reliability is mandatory - unlike commercial-grade variants such as 1.5SMC13CA-E3/57T.
How does the bidirectional configuration of the 1.5SMC13CAHE3/57T affect its circuit implementation?
The 1.5SMC13CAHE3/57T is inherently bidirectional - it clamps symmetrically in both polarities with identical VBR, VWM, and VC characteristics. This eliminates polarity concerns during layout; the device can be placed across any two points needing AC-coupled or floating-voltage protection (e.g., differential data lines, ungrounded power rails). Unlike unidirectional TVS diodes, it requires no cathode band alignment and provides equal surge immunity regardless of transient direction - simplifying design and reducing BOM complexity.
What is the thermal resistance of the 1.5SMC13CAHE3/57T, and how does it impact PCB layout?
The 1.5SMC13CAHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on the minimum recommended 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes standard FR-4 PCB with no internal planes. To maintain safe junction temperatures under repetitive surge conditions, designers must allocate adequate copper area and consider thermal vias - especially since its power dissipation rating drops above 25 °C ambient per Figure 2 in the datasheet. Failure to meet pad requirements risks premature thermal runaway during sustained transient activity.
Does the 1.5SMC13CAHE3/57T have a defined junction capacitance, and is it suitable for high-speed data lines?
The 1.5SMC13CAHE3/57T does not specify junction capacitance in its primary datasheet (document 88303), and Figure 4 only provides typical CJ curves for unidirectional variants. As a 1500 W general-purpose TVS, its capacitance is relatively high (estimated >100 pF at 0 V bias), making it unsuitable for USB 2.0, HDMI, or Ethernet data lines where low capacitance (<5 pF) is required. It is engineered for power rail and low-frequency signal protection - use dedicated low-capacitance TVS arrays (e.g., USBLC6-2SC6) for high-speed interface protection instead of the 1.5SMC13CAHE3/57T.
