Product details
Overview
1.5SMC10AHE3/57T 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 10 V standoff voltage (VWM), 14.5 V maximum clamping voltage at 103 A peak pulse current, and 1500 W peak pulse power capability with 10/1000 μs waveform - ideal for protecting MOSFETs and sensor interfaces in automotive ECUs.
For engineers reviewing the 1.5SMC10AHE3/57T datasheet, 1.5SMC10AHE3/57T pinout, 1.5SMC10AHE3/57T application, or 1.5SMC10AHE3/57T equivalent, key selection criteria include unidirectional polarity, AEC-Q101 qualification, 8.55 V minimum breakdown voltage, and thermal resistance of 75 °C/W - all critical for robust overvoltage protection in high-reliability embedded systems.
Technical Context
The 1.5SMC10AHE3/57T operates as a silicon avalanche diode with glass-passivated junction, delivering fast response time (<1 ns) and low incremental surge resistance to suppress transient energy before downstream ICs are damaged. Its unidirectional configuration enables integration into DC-biased circuits where reverse conduction must be blocked.
Rated for 150 °C maximum junction temperature and compliant with J-STD-020 MSL Level 1 (260 °C peak reflow), it supports automated SMT assembly without derating concerns. The device meets UL 497B recognition (QVGQ2) and is qualified to AEC-Q101 for automotive under-hood applications.
Key Specifications

|---|---|
| VWM (Stand-off) | 8.55 V - maximum continuous reverse voltage before clamping begins; defines safe operating margin below breakdown |
| VBR (Breakdown) | 9.50–10.5 V at 1 mA - precise avalanche initiation range ensures predictable turn-on during transients |
| VC (Clamping) | 14.5 V at 103 A - limits peak voltage seen by protected circuit during 10/1000 μs surge, enabling robust 3.3 V/5 V IC protection |
| PPPM | 1500 W - peak pulse power handling with standard 10/1000 μs waveform, supporting IEC 61000-4-5 Level 4 compliance |
| ID (Leakage) | 10 μA max at VWM - negligible standby current avoids battery drain or signal distortion in always-on systems |
| TJ max | 150 °C - enables operation in under-hood automotive environments and industrial enclosures without thermal derating |
| RθJA | 75 °C/W - thermal resistance to ambient on standard 8 mm × 8 mm copper pads; informs heatsinking requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10AHE3/52T | Same VWM (8.55 V) and VC (14.5 V), but 600 W PPPM rating and SMB (DO-214AA) package - smaller footprint, lower surge capacity | Preferred for space-constrained consumer PCBs where 600 W surge immunity suffices; not suitable for automotive load dump | Select when board area is critical and peak surge current remains ≤60 A; verify thermal performance with reduced pad area |
| 1.5KE10A-E3/54 | Through-hole TO-204AA (DO-41) package, same 10 V rating, but 1500 W rating with higher RθJA (100 °C/W); no AEC-Q101 qualification | Used in legacy industrial power supplies where manual assembly or high-voltage isolation is prioritized over automotive reliability | Choose only for non-automotive, non-SMT designs requiring identical electrical specs but accepting larger footprint and no automotive qualification |
Compared with SMBJ10AHE3/52T and 1.5KE10A-E3/54, the 1.5SMC10AHE3/57T uniquely combines AEC-Q101 qualification, SMC package thermal performance (75 °C/W), and full 1500 W surge capability - making it the sole choice for new automotive and high-reliability SMT designs requiring validated field performance.

FAQ
What is the maximum clamping voltage of the 1.5SMC10AHE3/57T under standard test conditions?
The 1.5SMC10AHE3/57T has a maximum clamping voltage (VC) of 14.5 V when subjected to a 10/1000 μs waveform at its rated peak pulse current of 103 A. This value is measured per JEDEC standards and guarantees that protected downstream circuitry will not experience voltages exceeding 14.5 V during such transients - a critical parameter for safeguarding 3.3 V and 5 V logic devices. The 1.5SMC10AHE3/57T maintains this clamping performance across its full operating temperature range.
Is the 1.5SMC10AHE3/57T qualified for automotive applications?
Yes, the 1.5SMC10AHE3/57T carries AEC-Q101 qualification, confirmed by Vishay's documentation and marked by the "HE3" suffix. It undergoes rigorous stress testing including temperature cycling, highly accelerated life testing (HALT), and ESD verification to ensure reliability in automotive environments such as engine bays and ADAS modules. The 1.5SMC10AHE3/57T is explicitly approved for use in automotive power distribution and sensor protection circuits.
What does the "HE3/57T" suffix indicate in the 1.5SMC10AHE3/57T part number?
The "HE3" suffix denotes RoHS-compliant construction with AEC-Q101 qualification, while "57T" specifies packaging in 7-inch plastic tape-and-reel format with 850 units per reel. This ordering code ensures traceability, compliance, and compatibility with high-speed pick-and-place equipment. The 1.5SMC10AHE3/57T is distinct from commercial-grade variants (e.g., E3/57T) due to its extended reliability validation and automotive-grade screening.
How does the thermal performance of the 1.5SMC10AHE3/57T compare to similar TVS diodes?
The 1.5SMC10AHE3/57T exhibits a typical junction-to-ambient thermal resistance (RθJA) of 75 °C/W when mounted on 8 mm × 8 mm copper pads - significantly better than smaller packages like SMB (100 °C/W) and competitive with larger DO-15 alternatives. This allows sustained power dissipation up to 6.5 W at 50 °C ambient and supports reliable operation in thermally dense layouts. The 1.5SMC10AHE3/57T achieves this without requiring external heatsinks in most automotive and industrial applications.
Can the 1.5SMC10AHE3/57T be used in bidirectional configurations?
No, the 1.5SMC10AHE3/57T is strictly unidirectional, as indicated by the "A" suffix and absence of "CA" in its designation. Bidirectional operation requires the CA variant (e.g., 1.5SMC10CAHE3/57T), which features symmetrical breakdown in both polarities. Using the 1.5SMC10AHE3/57T in AC-coupled or floating signal paths may result in unintended forward conduction or failure to clamp negative transients - always match polarity to circuit topology.
