Product details
Overview
1.5SMC16AHE3/57T from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMC (DO-214AB) package, designed for clamping voltage transients on power and signal lines. It features a 13.6 V stand-off voltage (VWM), 15.2–16.8 V breakdown voltage (VBR) at 1 mA, 22.5 V maximum clamping voltage (VC) at 66.7 A peak pulse current, and 1500 W peak pulse power capability with 10/1000 µs waveform - ideal for protecting MOSFETs and ICs in automotive power supplies.
For engineers reviewing the 1.5SMC16AHE3/57T datasheet, 1.5SMC16AHE3/57T pinout, 1.5SMC16AHE3/57T application, or 1.5SMC16AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, RoHS-compliant matte tin plating, MSL Level 1 moisture sensitivity, and compatibility with automated SMT placement on 8.0 mm × 8.0 mm copper pads.
Technical Context
This TVS diode operates as a voltage-clamping protection device that enters avalanche conduction when reverse voltage exceeds its breakdown threshold. Its glass-passivated junction ensures stable VBR tolerance (±5%) and low incremental surge resistance, enabling fast response (<1 ns) to ESD and lightning-induced transients.
The 1.5SMC16AHE3/57T is rated for 1500 W peak pulse power (10/1000 µs), 200 A non-repetitive forward surge current (8.3 ms half-sine), and operates across -65 °C to +150 °C junction temperature range. Thermal resistance is 75 °C/W (junction-to-ambient) and 15 °C/W (junction-to-leads), supporting reliable operation under transient stress without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off) | 13.6 V - Maximum continuous reverse voltage before leakage exceeds 1 µA; defines safe operating margin below clamping onset. |
| VBR (Breakdown) | 15.2–16.8 V at 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during overvoltage events. |
| VC (Clamping) | 22.5 V at 66.7 A - Peak voltage seen by protected circuit during 10/1000 µs transient; limits stress on downstream components. |
| PPPM | 1500 W - Sustains high-energy surges (e.g., ISO 7637-2 Pulse 1/2a/5a) without failure when mounted per recommended pad layout. |
| IPPM | 66.7 A - Peak pulse current capability under standard 10/1000 µs waveform; correlates directly with system-level surge immunity. |
| TJ max | +150 °C - Enables use in under-hood automotive environments and industrial power modules without derating concerns. |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC specification. |
Pinout & Package
Package: SMC (DO-214AB), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD 22-B102. Cathode indicated by band; polarity critical for unidirectional operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal in forward bias; connected to lower-potential side of protected line. | Must be tied to ground or return path in unidirectional configuration to enable clamping during positive transients on cathode side. |
| Cathode | Current exit terminal in forward bias; marked with band; connected to protected line. | Receives transient energy from supply/signal line; avalanche conduction diverts surge current to ground via anode path. |
Key Features
| Feature | Design Value |
|---|---|
| 1500 W peak pulse power (10/1000 µs) | Supports robust protection against IEC 61000-4-5 Level 4 (4 kV) and ISO 7637-2 Pulse 5a (75 V/300 ms) in automotive systems. |
| Glass passivated chip junction | Ensures long-term stability of VBR and leakage performance across temperature and lifetime, critical for safety-critical applications. |
| AEC-Q101 qualified (HE3 suffix) | Validates reliability for automotive electronics including engine control units, body controllers, and ADAS power domains. |
| MSL Level 1 (260 °C peak reflow) | Enables single-pass lead-free reflow assembly without moisture-related popcorn failure or delamination. |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (<1 ns response), 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 |
|---|---|---|---|
| SMBJ16A-E3/52 | Same VWM (13.6 V), lower PPPM (600 W), SMB package (smaller footprint, higher RθJA = 85 °C/W). | Limited to lower-energy transients (e.g., IEC 61000-4-2 ESD only); unsuitable for ISO 7637-2 Pulse 5a. | Select when board space is constrained and surge threat level is limited to ESD/EFT, not load dump. |
| 1.5KE16A-T | 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 prototyping where reflow compatibility and automotive qualification are not required. |
Compared with SMBJ16A-E3/52 and 1.5KE16A-T, the 1.5SMC16AHE3/57T uniquely combines AEC-Q101 qualification, 1500 W surge capacity, SMC package manufacturability, and MSL Level 1 compliance - making it the only option qualified for volume automotive SMT production with full load-dump immunity.

FAQ
What is the clamping voltage of the 1.5SMC16AHE3/57T under a 10/1000 µs surge?
The 1.5SMC16AHE3/57T has a maximum clamping voltage (VC) of 22.5 V at 66.7 A peak pulse current under the standardized 10/1000 µs waveform. This value is measured with the device mounted on 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per JEDEC standards, ensuring consistent performance in production layouts. The 1.5SMC16AHE3/57T maintains this clamping behavior across its full operating temperature range (-65 °C to +150 °C).
Is the 1.5SMC16AHE3/57T qualified for automotive applications?
Yes, the 1.5SMC16AHE3/57T carries the HE3 suffix, indicating full AEC-Q101 qualification for automotive use. It has passed stress tests including temperature cycling, high-temperature reverse bias (HTRB), and ESD per AEC requirements. The 1.5SMC16AHE3/57T is approved for under-hood and cabin applications such as engine control units, body control modules, and infotainment power supplies where reliability under thermal and electrical stress is mandatory.
What does the "HE3/57T" suffix mean in 1.5SMC16AHE3/57T?
The "HE3" denotes RoHS-compliant construction with AEC-Q101 qualification; "57T" specifies packaging in 7-inch diameter plastic tape-and-reel format with 850 units per reel. This ordering code ensures traceability, moisture sensitivity level 1 (MSL-1), and compatibility with high-speed pick-and-place equipment. The 1.5SMC16AHE3/57T meets JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards for industrial and automotive assembly.
How does the 1.5SMC16AHE3/57T compare to bidirectional TVS diodes like 1.5SMC16CA?
The 1.5SMC16AHE3/57T is unidirectional and optimized for DC power line protection where polarity is fixed (e.g., +12 V rail to ground), offering tighter VBR tolerance and lower leakage. In contrast, 1.5SMC16CA is bidirectional and suited for AC or data-line protection where voltage swings both polarities. The 1.5SMC16AHE3/57T cannot replace 1.5SMC16CA in AC-coupled circuits without redesigning grounding and polarity handling.
What is the thermal resistance of the 1.5SMC16AHE3/57T, and how does it affect layout design?
The 1.5SMC16AHE3/57T has a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W and junction-to-leads (RθJL) of 15 °C/W. To maintain safe operation during repetitive surges, PCB layout must use minimum 0.31" × 0.31" (8.0 mm × 8.0 mm) copper pads per terminal, as specified in Vishay's datasheet. Reducing pad size increases RθJA, risking thermal overload and premature failure - the 1.5SMC16AHE3/57T's performance is validated only with this layout.
