Product details
Overview
1.5SMC62CAHM3/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode designed for high-energy surge protection in power and signal lines. It features a 62 V breakdown voltage (VBR min/max = 58.9 V / 65.1 V), 1500 W peak pulse power (10/1000 µs), clamping voltage of 85.0 V at 17.6 A, and operates across -65 °C to +150 °C junction temperature range - deployed in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the 1.5SMC62CAHM3/H datasheet, 1.5SMC62CAHM3/H pinout, 1.5SMC62CAHM3/H application, or 1.5SMC62CAHM3/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification, SMC (DO-214AB) package compatibility, and compliance with UL 497B for telecom and automotive transient immunity standards.
Technical Context
This TVS diode uses a glass-passivated silicon junction optimized for fast response (<1 ps) to ESD and lightning-induced transients. Its bidirectional architecture enables symmetrical clamping in AC-coupled or floating signal paths without polarity constraints.
Rated for 1500 W peak pulse power under 10/1000 µs waveform with 0.01% duty cycle, it delivers low incremental surge resistance and stable clamping performance up to 150 °C junction temperature - validated per JESD22-B102 solderability and MSL Level 1 (260 °C peak reflow).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VBR (min/max) | 58.9 V / 65.1 V - ensures reliable conduction onset above normal operating voltage while avoiding false triggering during line tolerance excursions. |
| VWM | 53.0 V - maximum continuous reverse standoff voltage; defines upper limit of safe non-conducting operation in protected circuits. |
| VC @ IPPM | 85.0 V at 17.6 A - clamping voltage during full-rated 1500 W surge; determines maximum stress imposed on downstream ICs or MOSFETs. |
| PPPM | 1500 W - peak pulse power handling with 10/1000 µs waveform; supports IEC 61000-4-5 Level 4 (4 kV) surge immunity when properly laid out. |
| IPPM | 17.6 A - peak pulse current corresponding to 1500 W clamping; used to size PCB copper pads (8.0 mm × 8.0 mm recommended per terminal). |
| TJ max | +150 °C - maximum junction temperature; enables use in under-hood automotive environments and high-ambient industrial enclosures. |
| AEC-Q101 | Qualified - certified for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per AEC standard. |

|---|---|
Use Scenario: Protecting LIN/CAN transceivers and analog sensor outputs (e.g., pressure, temperature) from load-dump and jump-start transients in vehicle ECUs. IC Role / Device Role / Timing Role: Bidirectional TVS placed between signal line and ground to clamp ±85 V surges before reaching sensitive input stages. Use Value: Prevents latch-up or permanent damage to transceivers rated for ≤±40 V absolute maximum, enabling robust operation in 12 V/24 V systems. |
Use Scenario: Shielding multi-drop RS-485 communication lines in factory automation PLCs from EFT and surge coupling via long cable runs. IC Role / Device Role / Timing Role: Differential-line TVS connected across A/B terminals and to ground to suppress common-mode and differential-mode transients simultaneously. Use Value: Maintains signal integrity during 4 kV IEC 61000-4-4 EFT bursts by limiting voltage excursion to <85 V, preserving receiver threshold margins. |
| Telecom Line Protection | Power Supply Input Stage |
Use Scenario: Safeguarding Ethernet PHYs and DSL line drivers against lightning-induced surges entering via RJ-45 jacks in residential gateways and base stations. IC Role / Device Role / Timing Role: Primary-level TVS mounted at connector entry point, shunting surge energy to chassis ground before reaching isolation transformers. Use Value: UL 497B recognition validates compliance with telecom safety standards, reducing system-level certification effort and cost. |
Use Scenario: Clamping inrush and switching transients on 24 V DC input rails feeding motor drives, LED drivers, and programmable logic controllers. IC Role / Device Role / Timing Role: Parallel-connected TVS absorbing repetitive 1500 W pulses from inductive kickback or hot-swap events. Use Value: Enables use of lower-voltage-rated input capacitors and FETs by limiting transient overvoltage to 85 V, improving BOM cost and reliability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ64CA | Lower peak power (600 W), same 64 V VBR, SMB package (smaller footprint, higher RθJA = 85 °C/W). | Not AEC-Q101 qualified; limited to commercial-grade consumer/industrial equipment with lower surge exposure. | Select when space-constrained layouts preclude SMC and surge threat level is ≤IEC 61000-4-5 Level 2 (2 kV). |
| 1.5KE62CA | Same VBR/VC, through-hole DO-201 package, higher RθJA (100 °C/W), no AEC-Q101 or UL 497B listing. | Requires wave soldering; unsuitable for automated SMT lines or automotive under-hood thermal environments. | Choose only for legacy through-hole designs where rework to SMT is impractical and AEC-Q101 is not mandated. |
Compared with SMBJ64CA and 1.5KE62CA, the 1.5SMC62CAHM3/H provides superior surge robustness (1500 W vs. 600 W/1500 W), automotive qualification, and surface-mount scalability - making it the preferred choice for new automotive and industrial designs requiring high-reliability, high-volume assembly.

FAQ
What is the clamping voltage of the 1.5SMC62CAHM3/H and how does it protect downstream components?
The 1.5SMC62CAHM3/H clamps at 85.0 V when subjected to its rated 17.6 A peak pulse current (10/1000 µs). This limits the maximum voltage seen by protected ICs or MOSFETs to 85.0 V, well below typical absolute maximum ratings (e.g., 100 V for many automotive transceivers), thereby preventing overvoltage failure during surge events.
Is the 1.5SMC62CAHM3/H suitable for automotive applications?
Yes, the 1.5SMC62CAHM3/H is AEC-Q101 qualified and carries the HM3 suffix indicating halogen-free, RoHS-compliant, and automotive-grade construction. It is explicitly rated for under-hood use with guaranteed operation from -65 °C to +150 °C and validated for thermal cycling, HTRB, and ESD robustness per automotive requirements.
How does the bidirectional design of the 1.5SMC62CAHM3/H differ from unidirectional TVS diodes in circuit implementation?
The 1.5SMC62CAHM3/H has no polarity marking and conducts symmetrically in both directions, making it ideal for protecting AC-coupled or floating differential lines (e.g., CAN, RS-485) without requiring orientation checks during placement. Unidirectional variants require correct cathode alignment and cannot suppress positive-going transients on grounded lines.
What PCB layout guidance applies to the 1.5SMC62CAHM3/H to achieve its rated 1500 W performance?
To achieve full 1500 W rating, the 1.5SMC62CAHM3/H must be mounted on 8.0 mm × 8.0 mm copper pads per terminal (per Vishay Doc. 88303, Fig. 2). Minimizing trace inductance with short, wide connections to ground and protected line is critical - longer traces increase clamping voltage and reduce effective surge handling.
Does the 1.5SMC62CAHM3/H meet any safety certifications for end-equipment compliance?
Yes, the 1.5SMC62CAHM3/H is UL recognized under file E136766 per UL 497B for protectors, covering both unidirectional and bidirectional configurations. This certification simplifies end-equipment approval for telecom, industrial, and automotive systems requiring safety-agency validation of surge protection components.
