Product details
Overview
SMA5J13CAHM3/I from Vishay General Semiconductor is a bidirectional transient voltage suppressor (TVS) diode in SMA (DO-214AC) package, designed for high-energy surge protection on signal and power lines. It features a 13 V stand-off voltage (VWM), 14.4–15.9 V breakdown voltage (VBR), 500 W peak pulse power (PPPM), and clamps transients to ≤21.5 V at 23.3 A (10/1000 μs waveform), commonly used in automotive sensor interfaces and industrial I/O protection.
For engineers reviewing the SMA5J13CAHM3/I datasheet, SMA5J13CAHM3/I pinout, SMA5J13CAHM3/I application, or SMA5J13CAHM3/I equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance data, junction capacitance behavior, and direct replacement guidance for robust ESD/surge design validation.
Technical Context
This bidirectional TVS operates symmetrically in both polarities with no polarity marking, delivering consistent clamping performance across positive and negative transients. Its glass-passivated junction ensures stable VBR tolerance and low leakage (<1.0 μA at VWM), while the low incremental surge resistance enables rapid energy dissipation during 10/1000 μs surges.
Rated for TJ = -55 °C to +150 °C and qualified to AEC-Q101, the SMA5J13CAHM3/I supports automotive-grade reliability under thermal cycling and humidity stress. Its RθJA of 80 °C/W (on 5.0 mm × 5.0 mm copper pads) and RθJL of 25 °C/W define thermal limits for PCB layout and power derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC/AC bias margin for protected line. |
| VBR min/max | 14.4 V / 15.9 V - Breakdown occurs within this range at 1 mA test current; ensures predictable turn-on threshold across production lot. |
| VC @ IPPM | 21.5 V - Clamped voltage at 23.3 A peak pulse current (10/1000 μs); determines maximum stress imposed on downstream ICs. |
| PPPM | 500 W - Peak pulse power handling capability; defines single-event surge energy absorption limit per IEC 61000-4-5 Level 4 compliance. |
| ID @ VWM | <1.0 μA - Reverse leakage at stand-off voltage; critical for low-power sensor lines where quiescent current must be minimized. |
| TJ max. | +150 °C - Maximum junction temperature; sets upper bound for thermal design and derating curves in high-ambient environments. |
| RθJA | 80 °C/W - Junction-to-ambient thermal resistance on standard 5.0 mm × 5.0 mm pad layout; used to calculate temperature rise under sustained power dissipation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMA5J13CAHE3/I | Same electrical specs and AEC-Q101 qualification, but RoHS-compliant without halogen-free constraint; uses standard matte tin plating (not JESD201 Class 2 whisker-tested). | Preferred for commercial/industrial designs where halogen-free mandate is absent but automotive reliability is still required. | Select SMA5J13CAHE3/I if halogen-free material specification is not enforced by end-customer or regulatory requirement. |
| SMA6J13CAHM3/I | 600 W PPPM rating (vs. 500 W), same VWM/VBR/VC, identical package and AEC-Q101 qualification; higher surge margin due to larger die area. | Suitable for higher-risk zones like battery input rails or alternator-connected systems where IEC 61000-4-5 Level 5 surges may occur. | Choose SMA6J13CAHM3/I when system-level surge testing exceeds 500 W pulse energy or requires extended lifetime under repetitive stress. |
Compared with SMA5J13CAHE3/I, the SMA5J13CAHM3/I adds halogen-free compliance and JESD201 Class 2 whisker resistance - critical for automotive Tier 1 supply chains. Against SMA6J13CAHM3/I, it trades 100 W lower PPPM for tighter cost and footprint control where 500 W meets validated system requirements.

FAQ
What is the clamping voltage of the SMA5J13CAHM3/I at its rated peak pulse current?
The SMA5J13CAHM3/I clamps to a maximum of 21.5 V when subjected to its rated peak pulse current of 23.3 A under the standard 10/1000 μs waveform. This value is measured per ANSI/IEEE C62.35 and confirmed in the Vishay datasheet revision 09-Jan-2024, Document Number 88875. The clamping voltage directly determines the maximum stress imposed on downstream circuitry, making it essential for validating IC survivability in surge events. Designers must ensure that the protected IC's absolute maximum ratings exceed 21.5 V.
Is the SMA5J13CAHM3/I suitable for automotive applications?
Yes, the SMA5J13CAHM3/I is AEC-Q101 qualified and explicitly designated for automotive use via the "HM3" suffix, indicating halogen-free, RoHS-compliant construction with JESD201 Class 2 whisker resistance. It meets the thermal, mechanical, and reliability requirements for engine control units, body control modules, and ADAS sensor interfaces. The SMA5J13CAHM3/I operates across -55 °C to +150 °C and maintains specified VBR and leakage performance throughout its qualified temperature range.
How does the bidirectional nature of the SMA5J13CAHM3/I affect PCB layout?
The SMA5J13CAHM3/I has no polarity marking and functions identically in both directions, eliminating orientation constraints during placement. This simplifies PCB layout, reduces assembly errors, and avoids the need for silkscreen polarity indicators or asymmetric pad design. Engineers can route traces symmetrically and place the SMA5J13CAHM3/I inline with differential or AC-coupled signal paths without concern for anode/cathode alignment - a key advantage over unidirectional TVS diodes.
What is the thermal resistance of the SMA5J13CAHM3/I, and how should it be applied in thermal design?
The SMA5J13CAHM3/I has a typical junction-to-ambient thermal resistance (RθJA) of 80 °C/W when mounted on 0.2" × 0.2" (5.0 mm × 5.0 mm) copper pads per terminal, and a junction-to-lead resistance (RθJL) of 25 °C/W. These values guide PCB copper area allocation and derating calculations: for example, at 250 mW average dissipation, junction temperature rise is ~20 °C above ambient. Derating curves in Figure 2 of the datasheet must be applied for operation above 25 °C ambient.
Does the SMA5J13CAHM3/I have any special handling or soldering requirements?
The SMA5J13CAHM3/I is rated MSL level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30 °C/85 % RH and reflowed at a maximum peak temperature of 260 °C without baking. Its matte tin-plated leads comply with J-STD-002 and JESD22-B102 for solderability, and the package meets UL 94 V-0 flammability. No special pre-conditioning or post-solder cleaning is required, supporting standard SMT assembly processes used in automotive and industrial manufacturing.
