Product details
Overview
SMBJ13CAHE3_B/H from Vishay General Semiconductor is a bidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, designed for clamping voltage transients on signal or power lines. It features a 13 V standoff voltage (VWM), 14.4–15.9 V breakdown voltage (VBR) at 1 mA, 600 W peak pulse power (10/1000 µs), and clamps to ≤21.5 V at 27.9 A peak surge current - deployed in industrial sensor interfaces and telecom line protection.
For engineers reviewing the SMBJ13CAHE3_B/H datasheet, SMBJ13CAHE3_B/H pinout, SMBJ13CAHE3_B/H application, or SMBJ13CAHE3_B/H equivalent, key selection criteria include bidirectional clamping capability, AEC-Q101 qualification status, thermal resistance (RθJA = 100 °C/W), and compatibility with automated SMT placement on 0.2" × 0.2" copper pads.
Technical Context
This TVS diode operates symmetrically in both directions due to its bidirectional construction, enabling protection of AC-coupled or differential signal paths without polarity concerns. Its glass-passivated junction ensures stable leakage (<1.0 µA at VWM) and fast response time (<1.0 ns), critical for suppressing ESD and inductive switching spikes.
The device is rated for repetitive 10/1000 µs surges at 0.01% duty cycle and derates linearly above 25 °C ambient per Fig. 2. With a maximum junction temperature of +150 °C and MSL Level 1 moisture sensitivity, it supports lead-free reflow up to 260 °C peak.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 13 V - Maximum continuous reverse operating voltage before significant conduction begins |
| VBR (min/max) | 14.4 V / 15.9 V at 1 mA - Confirmed breakdown threshold range defining clamping onset precision |
| VC @ IPPM | ≤21.5 V at 27.9 A - Clamped voltage during 600 W transient, ensuring downstream ICs stay below absolute max ratings |
| PPPM | 600 W - Peak pulse power handling with 10/1000 µs waveform, supporting robust surge immunity per IEC 61000-4-5 |
| ID @ VWM | ≤1.0 µA - Ultra-low leakage preserves signal integrity in high-impedance sensor or data lines |
| TJ max. | +150 °C - Enables reliable operation in under-hood automotive or industrial enclosures |
| RθJA | 100 °C/W - Thermal resistance informs heatsinking requirements when operating near PD = 5.0 W limit |

| Glass passivated junction | Ensures stable VBR tolerance and low leakage across -55 °C to +150 °C operating range |
| MSL Level 1, 260 °C peak reflow | Compatible with standard lead-free SMT processes without pre-baking or special handling |
| Low incremental surge resistance | Minimizes clamping voltage overshoot during fast-rising transients (e.g., EFT bursts) |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ13CA-E3/52 | Same electrical specs and SMB package; RoHS-compliant commercial grade (non-AEC-Q101) | Lacks automotive qualification; suitable for industrial/commercial designs without AEC compliance mandates | Select when cost sensitivity outweighs automotive qualification requirements |
| SMAJ13CAHE3_A/H | Lower 400 W PPPM, SMA (DO-214AC) package - smaller footprint but higher RθJA (140 °C/W) | Reduced surge margin; limited to lower-energy transients or space-constrained PCBs | Choose only if board area is critical and surge threat level is ≤400 W |
Compared with SMBJ13CAHE3_B/H, the E3/52 variant offers identical clamping performance without AEC-Q101 validation, while the SMAJ13CAHE3_A/H trades 33% lower pulse power and higher thermal resistance for 30% smaller footprint - making SMBJ13CAHE3_B/H optimal for automotive and high-reliability industrial use cases demanding full 600 W headroom and validated qualification.

FAQ
What does the "CA" suffix indicate in SMBJ13CAHE3_B/H?
The "CA" suffix denotes a bidirectional configuration - meaning SMBJ13CAHE3_B/H conducts and clamps symmetrically in both forward and reverse directions. This enables protection of AC signals, differential buses, or ungrounded lines without polarity constraints, unlike unidirectional "A" variants that require correct cathode orientation.
Is SMBJ13CAHE3_B/H suitable for protecting USB or HDMI signal lines?
No - SMBJ13CAHE3_B/H is not optimized for high-speed data lines. Its junction capacitance (not specified in the SMBJ family datasheet but typically >100 pF for 13 V devices) would degrade signal integrity above ~10 Mbps. For USB/HDMI, low-capacitance TVS arrays like Vishay's USBxx series or discrete 5 V-rated devices with <10 pF CJ are recommended instead of SMBJ13CAHE3_B/H.
Does SMBJ13CAHE3_B/H require a heatsink for continuous operation?
No heatsink is required for transient suppression, as SMBJ13CAHE3_B/H is rated for 5.0 W steady-state dissipation only under infinite heatsink conditions. In typical PCB mounting (0.2" × 0.2" copper pads), its RθJA = 100 °C/W limits safe continuous power to ~1.25 W at 70 °C ambient - but since TVS operation is pulsed, thermal design focuses on single-pulse energy absorption, not steady-state cooling.
How does the HE3 suffix affect the specifications of SMBJ13CAHE3_B/H?
"HE3" indicates RoHS-compliant and AEC-Q101 qualified construction - including halogen-free molding compound, matte tin-plated leads compliant with J-STD-002, and full automotive qualification testing (HTGB, HTRB, TCT, ESD). Electrical and thermal specs remain identical to non-HE3 variants; the suffix reflects process and reliability enhancements, not parameter changes.
Can SMBJ13CAHE3_B/H replace SMBJ12CAHE3_B/H in an existing design?
Yes, with verification - SMBJ13CAHE3_B/H has a 13 V VWM versus 12 V for SMBJ12CAHE3_B/H, resulting in slightly higher clamping voltage (21.5 V vs. 19.9 V). If downstream circuitry has ≥2.0 V margin above 13 V, the replacement is acceptable; however, confirm that the increased VBR min (14.4 V vs. 13.3 V) does not delay clamping onset during marginal transients.
