Product details
Overview
1.5SMC13AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for high-energy surge protection with 1500 W peak pulse power (10/1000 μs), 18.2 V clamping voltage at 82.4 A peak pulse current, and 11.1 V stand-off voltage - deployed on power rails and signal lines of automotive ECUs and industrial sensor interfaces.
For engineers reviewing the 1.5SMC13AHE3/57T datasheet, 1.5SMC13AHE3/57T pinout, 1.5SMC13AHE3/57T application, or 1.5SMC13AHE3/57T equivalent, key selection criteria include clamping performance under 10/1000 μs transients, AEC-Q101 qualification status, thermal resistance (RθJA = 75 °C/W), and compatibility with automated SMT assembly on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a unidirectional clamping device with a glass-passivated junction, enabling fast response to voltage transients induced by inductive switching or ESD events. Its breakdown voltage is specified at 12.4–13.7 V (IT = 1.0 mA), and it exhibits low incremental surge resistance for stable clamping across repetitive surges at 0.01 % duty cycle.
The device is rated for TJ = –65 °C to +150 °C, meets MSL Level 1 per J-STD-020 (peak reflow 260 °C), and features matte tin-plated leads compliant with J-STD-002 and JESD 22-B102 solderability standards - confirming suitability for high-reliability automotive and industrial PCB assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 11.1 V - maximum continuous reverse operating voltage before leakage exceeds 5 μA; defines safe DC bias margin for protected line. |
| VBR (Breakdown) | 12.4–13.7 V at IT = 1.0 mA - guaranteed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 18.2 V at IPPM = 82.4 A (10/1000 μs) - peak voltage seen by downstream circuitry during worst-case surge; critical for IC-level protection. |
| PPPM | 1500 W - peak transient power handling capability; enables robust protection against lightning-induced surges and load dump spikes. |
| RθJA | 75 °C/W - junction-to-ambient thermal resistance on standard 8.0 mm × 8.0 mm copper pads; determines derating above 25 °C ambient. |
| TJ max. | +150 °C - maximum junction temperature; supports operation in under-hood automotive environments and enclosed industrial enclosures. |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMC (DO-214AB), molded plastic case with UL 94 V-0 flammability rating; cathode indicated by band on body; terminals are matte tin-plated for lead-free soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point in forward conduction | Connected to protected line's lower-potential side (e.g., ground or return path); defines unidirectional polarity orientation. |
| Cathode | Current exit point in forward conduction; clamping node in reverse bias | Banded end connects to higher-potential line (e.g., VCC, signal rail); reverse-biased operation triggers avalanche clamping at VBR. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 μs) | Supports IEC 61000-4-5 Level 4 surge immunity (4 kV line-earth) without derating on standard PCB layout. |
| AEC-Q101 qualification (HE3 suffix) | Validated for automotive applications including engine control modules, ADAS sensors, and infotainment power supplies. |
| Glass-passivated junction | Ensures stable VBR tolerance and long-term reliability under thermal cycling and humidity stress. |
| MSL Level 1, 260 °C peak reflow | Enables single-pass lead-free reflow without moisture-related popcorning or delamination. |
| Low incremental surge resistance | Minimizes voltage overshoot during fast-rising transients (<1 ns rise time), improving protection margin for sensitive ICs. |

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-E3/52 | Lower PPPM (600 W), SMB package (smaller footprint), same VWM/VC specs but higher RθJA (110 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for load dump or lightning. | Select when board space is constrained and surge threat level is ≤ Class 3 IEC 61000-4-5. |
| 1.5KE13A-E3/54 | Through-hole DO-201 package, identical electrical specs but no AEC-Q101 qualification or MSL Level 1 rating. | Not suitable for automated SMT production or automotive under-hood use; requires wave soldering. | Choose only for legacy through-hole designs or non-automotive industrial prototypes where reflow compatibility is not required. |
Compared with SMBJ13A-E3/52 and 1.5KE13A-E3/54, the 1.5SMC13AHE3/57T uniquely combines AEC-Q101 qualification, 1500 W surge capacity, SMC surface-mount compatibility, and MSL Level 1 reflow readiness - making it the only option qualified for volume automotive SMT production with full ISO 16750-2 compliance.

FAQ
What is the clamping voltage of the 1.5SMC13AHE3/57T under a 10/1000 μs surge?
The 1.5SMC13AHE3/57T has a maximum clamping voltage (VC) of 18.2 V at 82.4 A peak pulse current with a 10/1000 μs waveform. This value is measured per Figure 1 in the Vishay datasheet 88303 and defines the upper voltage limit imposed on protected circuitry during standardized surge events - critical for ensuring downstream ICs remain within their absolute maximum ratings.
Is the 1.5SMC13AHE3/57T qualified for automotive applications?
Yes, the 1.5SMC13AHE3/57T carries the HE3 suffix, indicating full AEC-Q101 qualification per Vishay's documentation. It has undergone stress testing for temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC standards - making it approved for use in automotive powertrain, chassis, and body electronics where reliability under thermal and electrical stress is mandatory.
What does the "HE3" suffix mean in 1.5SMC13AHE3/57T?
The "HE3" suffix in 1.5SMC13AHE3/57T denotes RoHS-compliant construction with AEC-Q101 qualification and matte tin-plated leads. It distinguishes this variant from commercial-grade E3 parts and confirms compliance with automotive reliability requirements, including MSL Level 1 moisture sensitivity and 260 °C peak reflow capability.
Can the 1.5SMC13AHE3/57T be used in bidirectional configurations?
No, the 1.5SMC13AHE3/57T is a unidirectional TVS diode, as indicated by the "A" suffix (not "CA"). Bidirectional operation requires the CA variant (e.g., 1.5SMC13CAHE3/57T). Using the unidirectional 1.5SMC13AHE3/57T in a bidirectional application would result in forward conduction during negative transients, potentially damaging the device or failing to protect the circuit.
What is the thermal resistance of the 1.5SMC13AHE3/57T, and how does it affect layout?
The 1.5SMC13AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal. This value assumes minimum recommended pad layout - reducing copper area increases RθJA, requiring derating of surge capability above 25 °C ambient per Figure 2 in the datasheet.
